Device for drilling holes. What is a jig for drilling holes: precision in making furniture with your own hands. There are different types of conductors

25.10.2019

Very often, when repairing furniture or assembling it, it is necessary to accurately drill holes for the firmament, dowels and other fasteners. If you drill a chipboard sheet, then it is almost impossible to do this with a simple drill, since the hole breaks and it is not always possible to make a right angle. Therefore, for such work, it is imperative to have a tool called a jig.

Classification of conductors

The main function of conductors is to ensure straightness in drilling wooden surfaces throughout the entire depth of the hole. Such fixtures in metal processing are used quite often and, as a rule, are supplied directly with the machine. In connection with the need to create such holes in the production of furniture in large quantities, such devices are in great demand among craftsmen.

There are such types of conductors:

If the conductor has sufficient rigidity, then it can be used not only on flat planes, but also for curved pipes, etc. In this case, it is fixed with a clamp. But in no case should it be used for mounting on wooden surfaces, as furniture can be damaged. You can buy it in the store, as well as do it yourself.

The conductor is in fact a template for making holes, with which such work can be done with maximum accuracy. Due to the simplicity of the structure of the structure, they are often used not only in the areas of furniture production. In particular, they are actively used in the field of mechanical engineering for drilling holes in various workpieces, etc. Do not forget about the furniture industry, where such a device is used for a variety of needs when assembling furniture fittings.

Features of independent production

When designing a conductor for confirmation, it is necessary to correctly calculate what functions it will have to perform in the future. You need to do it under the most commonly used fasteners in the house. If such a device is required by furniture makers for permanent work, then it is better to buy a factory sample, which is distinguished by great accuracy of work. In addition, manufacturers often include additional fasteners, stops and templates in the kit.

The price of such a device for professional use ranges from 400 to 1100 rubles. It depends on the immediate capabilities of a particular unit, the number of holes being made, their length, and so on. Many are interested in how to make a furniture jig with your own hands. Dimensional drawings are a must for novice craftsmen, as they allow you to make a design with high quality on the first try. Similar schemes can be found on the Internet.

Basically, the conductor has the following elements:

Product base. It is directly applied to the plane of the furniture, on which holes will be drilled.
Guide bushings. A drill goes through them.
Parts for surface clamping. As a rule, they are located on the end of the conductor.

To start designing your own conductor, you need to choose the right corner. It is better to make a non-equivalent corner, since it will have much more opportunities, and choose the maximum thickness of the shelf.

Next, you need to take care of the correct direction of the sleeve. It can be made from stainless steel. The length of the sleeve must be at least twice as long as the hole in which it will be located on the corner. The bushing in the hole should sit with an interference fit. The simplest and most common option is a shaft fit. Under the already known diameter of the sleeve, a corresponding hole is drilled in the corner, and then a landing is made. It is recommended to use a low interference fit.

There are cases when the conductor needs to be made for drilling deep holes. Then the sleeve is made with a collar. The number of possible holes, their length and the distance between them is chosen according to the specific needs of each master.

Several options can be used to mount the device:

Design for confirmations and dowels

A furniture jig for drilling holes for a dowel and a confirm is a very necessary device for furniture makers. Especially if chipboard material is used.

For these purposes, two types of conductor are used:

Clamp-on dowel jig with multiple functions. The basis of this design is a corner made of thick aluminum. Since the fixture is quite long, there is an additional mount in the middle. When turning the corner ninety degrees, the increased thickness of the fixture helps a lot. The bushings on the structure are located at the distance most often used for confirmations and dowels in the manufacture of furniture.
A two-slider jig, which is used to make a hole in two parts fastened together. The design consists of two strips, which are connected by fasteners. It has several holes, so you can install devices at different widths.

Scope of use

Furniture conductors are devices that no furniture maker can do without in the process of work. Such devices avoid the main problem in the production of furniture, namely, the entry of the drill at the wrong angle. If you make such a mistake, then it is subsequently very difficult to correct or even impossible. Such a device not only makes it possible to correctly direct the drill during operation, but also allows the tool to constantly keep the desired trajectory (even, perpendicular or at an angle).

Such devices are used both in the design and manufacture of furniture, and in assembly, when there is a need to make holes for attaching elements to each other. Often, for such actions, conductors are used for confirmations or dowels, without which even holes cannot be made. Also, this device is indispensable if it is necessary to make holes at an angle or at the end of a thin plate (it is especially important to use the device when working with chipboard plates).

When drilling holes using this design, the process itself is quick and simple. Fasteners allow you to work at any distance from the edge of the plate, and also regardless of its width.

In the furniture industry, dowels are very often used as fasteners. But at the same time, this option has already existed for a long time, and their use requires the mandatory presence of a drilling jig during operation. The only condition and at the same time a problem is the fact that the parts to be connected to each other must have a right angle when working. Therefore, such elements must be located exactly perpendicular to each other. When making holes for dowels and adding parts, it will be very difficult to do without a jig.

Furniture production is not the only scope of such devices. Often they can be used to make holes in pipes and other rounded parts. Special devices allow you to make high-quality holes even in the smallest tubes.

The principle of their work and dimensions may be different. Some narrow-profile models are better to buy than to produce on your own. But, on the other hand, the price of such devices is not small, so this is a disadvantage when compared with home-made models.

How to DIY

Most simple designs are cheap, and professional furniture makers are not puzzled homemade production, and prefer to buy factory models. But there are also such masters who want to make such a device with their own hands.

To create a conductor yourself, you need to use the drawings, of which there are a lot on the Internet. With your own hands, you can make simple designs for confirmations and more complex ones for dowels.

For production, you need to prepare a tool:

drill;
classic set of tools for a locksmith;
welding;
Bulgarian.

The simplest conductor can be made from improvised means, which are basically found in any household, in a workshop in a country house or garage. To create it, the simplest materials are suitable, such as fittings, metal sheets and wooden blocks etc. They allow significant savings in the production of such a device.

The manufacture of such a device should be carried out in several stages:

In order to have little dust during operation, it is required to mount half plastic bottle. It will also collect dust.

A furniture jig is a simple mechanical device that speeds up and simplifies the process of drilling holes. The use of this device allows you to create technological holes without pre-applied markings and do it with perfect accuracy, as well as a verified inclination. The device is indispensable during the assembly of furniture structures, during carpentry work. For use in everyday life and in the production of small volumes, it is very easy to make a furniture jig with your own hands.

In fact, a furniture conductor is a regular template with holes of the desired diameter. The working part of the device is a rectangular block of solid material with holes located according to the required markings. For convenience, it can be equipped with regulating and fixing mechanisms. Based on the simplicity of the design, you can quickly make stencils for furniture with your own hands from improvised means.

The jig provides the desired direction of the drill at an angle of 90 degrees to the surface, eliminating the possibility of deviation. This is especially important when working on narrow pieces of furniture, such as the ends of walls or doors. Without this device, it is quite difficult to maintain the desired angle, which can lead to marriage, because even a slight deviation in the direction of the mounting hole can make it impossible to assemble individual elements into a single structure.

For perfect matching of furniture elements to each other also great importance has the accuracy of the location of the holes for fasteners. Those who make furniture with their own hands are often faced with the need to create a series of identical holes at a certain distance from each other. To facilitate the work, to make it faster, it is easier not to markup each time, but to apply a template.

With the help of the conductor, you can work with different furniture materials: wood, chipboard, MDF.

The choice of model for manufacturing

Conductors of industrial production are highly specialized and universal. Templates of the first type are used to perform certain operations on typical parts. Universal devices are suitable for working with different materials and objects of various configurations.

By design features and functionality conductors are divided into the following types:

overhead - when used, they are applied to the surface in the desired area, fixed with clamps or held by hand. Used for drilling holes in flat parts;
rotary - the working part moves both in vertical, and in horizontal planes. It is used when working with elements of complex geometric shape and for creating holes, the axis of which should be at an angle;
tiltable - used to create holes in perpendicular planes.

To mark the places for drilling holes, a marking jig is used. It is much thinner and lighter.

The conductor device can be specially created for a certain type of fastener: dowels, confirmations, screws, corners. There are devices to simplify the process of installing fittings.

By type of fixation furniture conductors can be sliding or fixed. The former move freely over the surface if necessary, the latter are rigidly fixed in the right place. The presence of an adjustment mechanism will help to combine the device with different types of workpieces.

For large furniture manufacturers, the availability of a variety of accessories plays a decisive role, as they significantly reduce time costs. In this case, the cost of the tools does not really matter. A completely different approach to acquiring the necessary equipment from those who have a small furniture production or from independent craftsmen who make certain types of furniture. In this case, making furniture templates with your own hands is much cheaper and more practical. The choice of the right options, the complexity of the fixture is determined not only by production needs, but also by the skill and experience of furniture manufacturers.

Materials and tools

For the manufacture of the device, it is necessary first of all to determine the tasks that it will perform. Accordingly, the necessary material is selected from which the furniture template will be made by hand. The most durable, reliable and "long-playing" is considered to be a metal conductor. To create a furniture conductor for drilling with your own hands, it is permissible to use wood, plywood, textolite, plexiglass. This is due to lower labor costs and low cost of material. All this is important, especially if you are going to make several different templates yourself.

For the manufacture of a conductor, a piece of reinforcement, a bar or a plate is suitable - something that is sure to be found in any garage or home workshop. To make a simple marking device, you can take a regular school ruler - wooden, plastic or metal.

Of decisive importance in the manufacture of the jig is the exact calculation of the location of the holes on the workpiece. You can take a ready-made scheme or make it yourself. The latter option is preferable, since the dimensions in the drawings must correspond to the tasks being solved.

Of the tools you will need:

drill;
grinder or jigsaw;
a set of locksmith tools;
clamps;
vise.

In the manufacture of the jig, perfectly precise drilling of pilot holes and hardening of the finished fixture will be required.

Drawing homemade conductor for drilling holes for confirmations

Manufacturing steps

Consider the process of creating a metal conductor device for confirmations. This fastener is most often used in furniture assembly:

a piece of the desired length is cut off from a metal bar of square section (10x10 mm) using a grinder. The ends of the resulting segment are leveled with a file and cleaned of burrs. Corners and edges can be rounded for convenience and safety of use;
holes are marked on the workpiece. Their centers should be located at a distance of 8 mm from the side face (chipboard sheet thickness - 16 mm). From the end and between the holes should be 32 mm, according to the generally accepted system of furniture fastenings. For marking, you can use a carpenter's corner or caliper. It is better to make marks on the part with a sharp metal object - an awl or a large needle. You can use a core and a hammer to make holes for the initial installation of the drill. It is important when drilling holes to prevent displacement of the drill and make them strictly perpendicular to the surface of the workpiece;
using a drill with a diameter of 5 mm, make holes;
to create an emphasis, you need to cut a piece of the desired length from a metal plate (1x25 mm);
finish the edges with sandpaper;
bend the workpiece at a right angle, holding it in a vise. Fold the parts, aligning them coaxially;
fasten the parts in this position with a clamp;
on the side of the plate along the length of the device and at the end, drill holes corresponding to the size of the screw. Cut threads and fasten parts;
cut off the excess of the stop plate, process the edges.

In the manufacture of cabinet furniture, it becomes necessary to be able to accurately and quickly drill into the end of parts. As a rule, this need is due to the use of euro screws (confirmants), in which holes with diameters of 4.5-5.0 mm are drilled into the end of the parts (depending on the density of the plate) to a depth of 35-55 mm (depending on the length of the euro screws).

Of course, there are special drilling and welding machines for such purposes, but they are not easily accessible to private furniture makers or small organizations due to their high price, plus, the machines are not convenient due to their exclusively stationary use. To simplify the work of a furniture maker, conductors were invented - small devices for precise drilling with a conventional hand-held electric drill. Today there are several manufacturers on the market, paying no small price, you can buy a ready-made jig. This article will discuss how a good home-made jig can be made from improvised and easily accessible material in a couple of hours.We use ball bearings as guide bushings. The bearings are made of durable steel and will last a long time. In order for the drill to be well oriented in the jig, two bearings are used for each working distance (bearings are arranged coaxially one under the other).

To make a conductor (for three working fixed distances), we need:

A piece of MDF board 16mm thick.
A piece of MDF board 10mm thick.
Six pieces (a pair for each working distance) of any ball bearings with an inner diameter of 5.0 mm, an outer diameter of not more than 16 mm. The height of the bearing should be as small as possible and no more than 8mm.
A dozen self-tapping screws 4x25 mm.
Glue PVA, "Superglue".
Futorka furniture with internal thread M6 (see photo).
Screw M6x50. Nut M6. Washer Grover 6mm.

Manufacture of the body of the conductor.

First, you need to make the case itself. There is no need to explain anything in particular about the case, everything is elementary. Transverse section cases - the letter "P" with one end (closed) wall. This wall will be used as a stop, will set the zero point, the starting point for drilling. When drilling, the stop is pressed against the end of the part. Main dimensions:

The external size of the conductor is arbitrary.
The upper part, in which the bearings will be planted, is made of 16mm MDF, the rest of the parts are 10mm MDF.
The distance between the two sidewalls (where the workpiece will be placed) is16.5mm whatcorresponds to the actual thickness of the plate plus a small gap for ease of installation and removal of the conductor.
The distances between the centers of the bearings and the stop: 50, 70, 100 mm, are the most common in furniture practice.

To assemble the housing, it is necessary to accurately cut out all four parts (top, two side and one end), measurements are recommended to be performed with a caliper. Further, holes for self-tapping screws are marked and drilled, which will fasten all the parts together. The body is assembled with PVA glue.

The distance between the side walls of the conductor is 16.5 mm (for laminated chipboard with a nominal thickness of 16 mm).

Fitting bearings.

After the glue dries, we proceed to marking and punching the holes for the bearings. We try to be very accurate in this operation! To drill holes for the bearings, we need either a drill fixed in the rack. It is very difficult to perform accurate drilling by hand, but with a certain skill it is possible. We mark the centers of the bearings with a pencil, kernim. By punching, we drill three through holes with a diameter of 2 mm. We clamp a feather drill (punch) into the drill chuck, the diameter of the punch should be equal to the outer diameter of the bearings. We drill two blind (non-through) holes for each bearing on each side of the previously drilled through hole. The drilling depth of the punch (the penetration depth of the central pin is not taken into account) should be approximately 1 mm greater than the height of the bearing. As a result, we should get six mounting holes (three on each side) for the bearings. You can try to insert the bearings into the seats, the bearings should enter freely, but without noticeable play. After fitting, you need to lubricate the outside of each bearing with glue and put it all the way in its place. If "Super Glue" is used (it absorbs and dries quickly), then this operation is performed using a rubber mallet.

Making an adjustable stop.

To be able to drill at any arbitrary distance from the stop (not only 50, 70, 100 mm), it is necessary to supplement the jig with a simple adjustable stop - a long screw. We drill a through hole in the center of the end stop with a diameter of 0.5 mm less than the outer diameter of the furniture fitting (see photo). We twist the futorka. We screw a long screw into the futorka, not forgetting to first screw the nut onto the screw and put on the Grover washer. Now, by changing the depth of the screw, you can set any drilling distance from 0 to 100 mm.

Drill out. This maximum depth can be drilled.The length of the drill used and the depth of its fastening in the drill chuck should be selected taking into account the thickness of the conductor (that is, almost the total height of the two bearings).

If desired, the surface of the conductor can be sanded with fine sandpaper, primed and painted (for example, spray enamel). Practice has shown that the accuracy of drilling with a jig is no worse than +/-0.5 mm and largely depends on how the actual thickness was made (plateschipboard) differs from the calculated thickness. In any case, an error of a maximum of half a millimeter is not critical for end-to-end drilling in the manufacture of cabinet furniture.

The jig for drilling holes is a bar small size, which has hole patterns located at certain angles and having different diameters for drilling. In fact, this tool is designed to solve the problem: to position the drill at the right angle to the web of the material being processed. After all, sometimes it is simply impossible to correct such a mistake.

Structural features and types of conductors

The drilling jig is actually a hole pattern that allows you to make them with maximum accuracy. They can be divided into two types:

when the drilling axis is at right angles to the surface of the material;
when the axis passes at an acute or obtuse angle with respect to the plane.

The tool has such versatility that it finds application in various industries. For several decades, it has been very actively used in the engineering and construction industries. After all, it allows not only to drill holes in the desired workpieces at different angles and with excellent accuracy, having different configuration features. It makes it easy to drill holes in various building structures, as well as pipes of any material, etc. The conductor is often used in the furniture industry, as it greatly simplifies the process of fastening fittings and the assembly of its various parts. In fact, this is only a small front of the tasks that the conductor is able to solve.

Instrument classification

According to the functionality and design functionality, the drilling jig is divided into types:

overhead. The name comes from their functional way of working, that is, they are superimposed on the blank part or the surface to be processed, attached to it with special clamps or held by hand. Such a device is applicable for drilling flat surfaces, for example, boards, MDF boards and chipboard. It is called a furniture jig for drilling holes. Thanks to the use of the jig, the holes themselves are very neat and verified;
rotary. Such templates are great for drilling a round or cylindrical surface. Thanks to this design, the axis occupies a horizontal, vertical and inclined position to the surface. This is possible thanks to bushings that can guide the drilling line;
universal. Tools of this design are very popular in small industrial production, where quick adjustment to the existing surface plays an important role. Due to their uniqueness, they are also in demand in the household when you have to work with different materials, planes and surfaces;
overturned. In terms of functionality, they resemble something universal. They are necessary when you want to make a hole in different planes and at different slopes. It is very convenient for carrying out some repair work when you want to drill a hole in the wall without a lot of time and at a specific angle;
sliding. According to its name, such a conductor does not have to be attached to the surface where it is supposed to be applied. It should be noted the inconvenience of such a conductor in handling, as it requires constant hand holding;
fixed. Unlike sliding conductors, they are attached to the place where they are intended to be used. It is much easier to fix them, but due to their design they limit the scope of human work. This can be clearly seen when working on walls or vertical planes with only one spindle.

Such templates allow you to maintain perpendicularity between the pipe or sphere and the drill itself. It is very important.

Furniture jigs for drilling holes deserve a separate description.

It is practically impossible to do without conductors or similar templates in the production of furniture, especially when assembling all the structural elements of future furniture. First of all, they correct such an error as an incorrect angle of entry of the drill into the workpiece. As you know, correcting such a mistake is very difficult, sometimes even impossible, and if possible, it takes a lot of time. The jig not only allows you to position the drill relative to the part, but also allows it to move away from the intended direction of drilling during operation.

They are used when it is required to drill holes for fasteners. In this case, a conductor is used for confirmants or dowels. Without them, drilling such holes is simply impossible. And how often does it happen that when assembling furniture, there is a shortage of a certain number of holes necessary for the final assembly.

Angle hole jig

The jig for drilling holes at an angle is used for assembling furniture. Often it is used for drilling not too thick MDF boards or chipboard, plywood. Also used in production. They can be manufactured both in a specialized version, for specific operations, or in more universal form. They reduce the time for making inclined holes. Moreover, by eye to make them the same way exactly will not work.

At home, drilling at an angle is not often necessary, but such a need arises. This kind of conductor can be made independently, or you can buy it. The reason is that if you do not engage in mass production, then preparing templates for non-standard holes will most likely not justify the cost. It will be easier and cheaper to try to drill the hole as needed, but with small deviations, than to make templates. It may never be useful again. It's up to the owner to decide.

The jig for drilling holes for dowels is one of the simplest templates in its version. However, you should be aware that such templates should simplify the work of the master, and not complicate it when he is forced to use complex devices.

Used to assemble furniture. It should provide simultaneous drilling of holes without changing the device. Used for manufacturing different materials with different strength properties. The most durable can be considered a unit made of steel.

Conductor for confirmation of variety and the possibility of manufacturing

Also the easiest jig for drilling a hole for confirmation. Such a conductor is assembled at home without much difficulty. It makes sense to assemble it yourself if you are professionally manufacturing furniture. For drilling one or two holes it is impractical.

More complex drawings can be taken from any source on the Internet. With the complication of the constructiveness of the device, its range of use expands. In order not to bother with structurally complex devices, they can be made from readily available materials, such as metal plates, wooden bars, fittings or corners. Welding consumables may be required for working with metal, although locking elements can be attached to threaded bolts.

Advantages and disadvantages

According to its functional purpose, the conductor acts as a template, according to which it is necessary to drill a hole in the required material with maximum accuracy to the original. Such a template greatly facilitates the work of the master when it is necessary to drill a strictly vertical, horizontal or inclined hole.

The master no longer needs to make sketches, measurements, having such a tool with him. The drill is located strictly at the required angle, which is necessary in the process of work and cannot deviate. This improves the accuracy of work, which can be seen in the example of deep holes.

To work with furniture, the conductor must meet the following requirements:

it should help and speed up the process of assembling furniture, not require the use of sophisticated equipment;
allow you to make several holes at once without the need for manual markings;
increase work with a drill;

The materials from which conductors are made have different strength characteristics. Basically it is plastic and glass from organic raw materials. But the most durable are obtained from metals, namely steel. Therefore, when choosing, you should pay attention to the following characteristics:

minimal deformation under heavy loads;
a clear axis of the direction of the drill;
no heating during operation.

AT furniture production use lighter conductors that are easy to handle. Factory or homemade options can be used.

It should be noted that a real master has a trained eye, so often all these devices are not needed to make the hole correct.

A clear advantage of such tools is ease of use. With their help, even an inexperienced person will be able to do all the work at the level of a skilled worker. Here you do not even need to do any complicated calculations and have tremendous experience. Its main purpose is to speed up the work process many times over.

Homemade conductor apparatus

A do-it-yourself jig for drilling holes is a great alternative to store options. Since the store does not always have exactly the option that is required at the moment. It can be assembled at home.

Let's consider a more popular and standardized option, suitable for more frequently performed jobs like furniture assembly.

Scheme for assembling the conductor Reinforcement with a diameter of 10 mm or more is required. With help cutting tool, for example, grinders, cut into segments of the required length. Clean the blanks with sandpaper. According to the standard, all drilled holes have a distance of 32 cm between them. Make marks and drill holes. The next step is to create reference points for our blanks. For these purposes, a plate made of any metal is perfect. Thickness from 1 mm. It is unwise to use a thicker plate, as it only adds weight to the entire device. They are connected together and then places for threaded fastening are outlined. They are connected and attached to each other. That's it, the device is ready to use.

The main purpose of the conductor, it is the most important thing, is to simplify the work with the drill and reduce the assembly time of furniture. The difference between purchased and homemade device is its adjustment to the specific needs of the master.

Today in construction, devices are used that facilitate the processing of materials. For example, a jig for drilling holes is one of those devices that allow you to work without the use of any marking tools.

What is a product?

The presented device allows you to do the job as accurately as possible. It is a special box that provides the necessary hole parameters. That is, you can easily adjust the angle of entry of the drill into the material being processed. Moreover, if there are several details, then drilled holes will match.

I must say that such devices can be purchased at any hardware store. Their cost ranges from 1000-2500 rubles. However, the jig for drilling holes can be made independently. This is especially necessary if special parameters are required for operation.

Advantages of the device

The jig for drilling holes has the following advantages:

Affordable cost and the possibility of self-manufacturing.

There is no need to use a ruler, pencil or other means to mark the surface to be treated.

Reducing the complexity of the procedure.

Very simple use of the product, intuitive even for an amateur.

As you can see, the hole jig is very useful device for household or for a small business.

Applications of the product

In principle, such a device can be used almost everywhere. For example, most often it can be found in the process of making furniture. In this work, precise parameters are required. The use of measuring instruments takes a large number of time. This entails additional expenses that can be detrimental to a small business.

The conductor is also a very important device in mechanical engineering. This is where equipment plays a huge role. It must be as accurate as possible. As you can see, the presented device is quite common and useful. It makes the job much easier.

Device design

The jig for drilling holes, the drawing of which you can see in the article, may have a different design. It all depends on the purpose for which the device will be used. For example, if you purchased an apparatus in the form of a small strip or a corner with holes drilled in one line, then with its help you can make holes in one row at a right angle.

If you do not need such a design, but need a more complex version with holes that are not on the same axis, then you will have to manufacture the device yourself. How to do this, you can find out further. However, first you need to understand the varieties of products presented. As you can see, the conductor for perpendicular drilling of holes has a not too complicated structure, which even an inexperienced master can figure out.

Apparatus classification

So, we can distinguish the following types of devices:

Stationary. They differ in that they do not have rotary elements capable of moving the workpiece. That is, those products that are drilled are of the same type.

Overhead. Their feature is the simplicity of design and low cost. To work, such a device just needs to be put on the part that will be processed. At the same time, it should be fastened with a washer and a nut.

Overturned. They are able to drill multiple holes in one part. However, they can have a different angle in relation to each other.

Swivel. In this case, the location of the drill bushing is determined by the dividing disc.

Rocky. Such products are most often installed on professional drilling machines. They are in particular demand in the engineering industry.

How to choose the right device?

In order for the jig for drilling holes, the photo of which is presented in this article, to be able to successfully cope with the tasks assigned to it, you need to purchase correct device. When choosing and buying, try to be guided by the following recommendations:

1. Type and purpose of the device. This setting is the most important. If you pick up the wrong device or its equipment, then it will be useless for you, and money will be thrown away.

2. The cost of the device. This parameter is also important. Do not give preference to the cheapest products that can disperse on the first use. Buy durable metal devices.

3. Manufacturer's warranty. Don't buy things in the basement. There you are not insured against fakes or defective goods. It is better to contact an official certified point of sale, where you can exchange the product under warranty if it does not suit you or is not functional.

4. Additional features. To date, a jig for drilling holes in pockets can be equipped with special devices that help eliminate dust during operation, or other devices.

5. Manufacturer. Here it all depends on your taste and the reputation of the manufacturer. Now the most popular jig for drilling holes is Wolfcraft.

Features of self-production

This is not at all difficult to do. To start, you need to choose necessary material. For this purpose, a channel or corner is best suited. Naturally, before processing the workpiece, it is necessary to make a template, according to which holes will be drilled. The scheme can be drawn on a regular sheet of paper.

Next, you need to make markings on the workpiece itself. After that, it must be clamped in a vice or with clamps, and only then start drilling. Keep in mind that doing this strictly perpendicular is quite difficult. The fact is that manually you can make a hole with a certain deviation. Moreover, the thicker the workpiece you choose, the more difficult it will be to work with it.

Next, you just need to drill holes in the marked places. When doing this, consider the diameter of the drill. It must exactly match the size of future holes on the material being processed. It is best to use a drilling machine for this purpose. It is he who will achieve the desired angle of 90 degrees. If there is no drilling machine, then the drill must be fixed so that it does not deviate. To do this, you can use all kinds of stands.

Features of the device

The KWB drilling jig, like any other device of the presented type, must be used correctly. Only in this case you will be able to achieve a positive result. So, try to comply with the following conditions:

During operation, all parts, as well as the device itself, must be cleaned as much as possible from dust or other contaminants.

Try to choose exactly the drill that will suit you in diameter.

Please note that during the installation of the jig, it must lie flat against the plane of the table. Naturally, at this stage, you should also set the drilling depth.

When choosing the speed of the drill, it is necessary to check the correct setting of the drill for runout.

The workpiece must be very firmly fixed on the jig.

Through the guide sleeve, the drill must be brought to the product and drilling started.

Please note that during operation, do not press too hard on the tool. Otherwise, the drill may simply break or lose its sharpness.

After completing the work, it is necessary to carefully remove the tool from the part and unscrew the jig.

During the implementation of all manipulations, try to follow the safety rules as much as possible. For example, wear protective clothing, gloves and goggles. If you feel that the tool has started to act up, immediately stop working. Otherwise, you risk injury.

That's all the features of the conductor. Good luck!
