I assembled this chip blower a year ago. During this time, I completely ran it in and I can say that the design is quite working. used for chip blower asynchronous motor at 1.5kW/3000 rpm. The impeller is assembled from plywood. The size of the impeller was chosen so that the motor would not be overloaded. The blades are curved and the impeller rotates with the curved side forward.

I assembled this chip blower a year ago. During this time, I completely ran it in and I can say that the design is quite working. Unfortunately, the format of the competition does not allow describing in detail the manufacturing process and the reason for choosing the shape of the parts, so I offer only short description and focus on the most important points. For the chip blower, a 1.5 kW/3000 rpm asynchronous motor was used. The impeller is assembled from plywood. The size of the impeller was chosen so that the motor would not be overloaded. The blades are curved and the impeller rotates with the curved side forward. To bend the blades I used two 3mm plates and glued them together. The impeller is attached to the engine through a plywood pulley. To remove any beating of the pulley, it was machined directly on the native engine. The impeller blades are glued to the sidewalls using grooves. Manually calculating the radii was quite difficult, but I have a homemade milling machine with CNC (based on the milling cutter Enkor FME-850). With the help of it, all the details came out as they should, although it was necessary to slightly adjust each blade individually in its place. But after gluing and installing on the motor shaft, there was a slight runout in both axes. The beauty of a wooden impeller is that it can be easily turned, but it was dangerous to run it with beats at 3000 rpm (and its diameter is 360mm and thickness 120mm). Therefore, I attached the Enkor LME-900 belt sander (it has convenient grooves for fastening with clamps) and removed the beats by rotating the impeller manually. Next, balancing was carried out by drilling plywood from the back of the impeller. After that, I already ventured to start the engine and made sure that everything worked well. The impeller body was also assembled from bent plywood in the form of a “sandwich” of 2 plates 3 mm thick. The housing cover is rigidly attached to the engine, and the housing to it with the help of valves for quick disassembly. All connections at the final stage are glued with window rubber seal for tightness. The next step was to assemble the cyclone itself. It consists of two parts and is made of plywood and galvanized sheet. Top part creates a swirl of air, and the cone directly separates the debris. The ends of the cylinder are cut and glued to the liquid nails. I cut it with a grinder Enkor UShM-900/125M. The ramp was cut out of galvanized steel using an Enkor ACCUMaster AKM1802 screwdriver and the Cricket tool. All connections are treated with sealant on the non-working side. The engine is hung on two simple brackets. The engine itself, together with the top cover of the snail, is suspended from brackets on rubber shock absorbers, which also dampen the beats during start and stop. At the cyclone, the upper plywood part of the body is the carrier and is rigidly attached to the wall. A "bucket" on wheels is attached from below, which is convenient. At this point, the chip blower was ready for testing. Gradually, the wiring was collected. I used the usual sewer pipe at 110 and 50mm. It does not fit well with a 100mm corrugated hose and I used a 100mm round ventilation pipe in these places. For convenience, valves and "scoops" for sweeping were made. In addition, I added remotes remote control. That's all. Thank you for your attention.

Gotta cut sheet metal up to 1.6 mm thick? The nozzle on the drill "Cricket" will solve the problem at no additional cost! What else can your drill do? You'll find out in just a few minutes!

The most common nozzles and their descriptions

There are several hundred different nozzles and they all differ from one another in some way. It is simply impossible to cover the entire range of goods, so let's start from the most "running" models that can replace your expensive tools. With their help, you can perform basic construction and finishing work, process a variety of surfaces and materials. We do not take the drill and the "blade" into account, only additional accessories. Let's consider in more detail.

  1. Crowns. Unique nozzles for making holes in wood. An indispensable thing in the manufacture of furniture. They have different diameters and heights. As a result of the work, you get perfectly even holes in any wood. The cost of such crowns is from 40 to 700 rubles per piece (depending on the manufacturer, steel grade, height and other parameters).
  2. Nozzle "screwdriver". There is nothing easier than making a conventional screwdriver. It is enough to buy inexpensive cross-shaped and straight tips and you immediately have 2 types of screwdrivers. More precisely - 3 types, since there is also a percussion (perforating function on a drill).
  3. Metal brush-circle. Used for metal work (mainly), it is a metal bristle that is located around the shaft, and it, in turn, is mounted in the cartridge. This shape is made for maximum balance of the nozzle. When you turn on the device, the brush has a very high speed and removes all rust and bumps in seconds!
  4. Corolla. For mixing building mixtures, a specific nozzle is used in the form of a long screw and a large holder, which is inserted into the tool chuck. With something like this you can mix an excellent tile adhesive in a few minutes, mortar for laying bricks and whatever you want. Yes, even mix the paint with a solvent! The quality of the mixture is much better than in the case of manual preparation of the mixture.

These nozzles are known to almost every builder and have gained immense popularity not only in the construction industry, but also in many household tasks.

Rarely used nozzles

  1. Jigsaw. Incredibly, a high-quality jigsaw can be obtained from an ordinary tool with a rotating chuck. This is an adapter nozzle that converts the revolutions of the cartridge into useful energy that launches a complex saw swing mechanism. As a result, you can process thick boards, and make the most complex patterns.
  2. Flexible shaft for drill or flexible drill. In fact, this is a standard nozzle, only it does not break when bent, but deforms without loss of strength. There is an opportunity to get to the most inaccessible places, for example, in the head of a car, when installing industrial transformers, and the like.
  3. Angle nozzle for a drill. There are several versions of this thing, but the most popular is the grinder. You get a high quality tool for metal cutting, polishing and grinding.
  4. "Cricket". Another rare attachment that allows you to make scissors for metal. Works with material up to 1.6 mm thick, which is simply amazing. You can cut any pattern you need - it is very easy and convenient to control the direction of the cut.

These nozzles are not always relevant, sometimes it's easier to buy the appropriate device and not mess with them. If it is necessary to perform one-time work- it makes sense to purchase an inexpensive adapter or device to solve a particular problem.

Grinding and polishing

In a separate group it is necessary to take out a huge number of nozzles intended for polishing, cleaning, grinding the surface. With their help, you can not only remove paint or unevenness from metal or wood, but even remove a few millimeters of material, increase its strength and much more! Let's consider some of them.

  1. Grinding nozzle for a drill. Designed to remove rust on metal, eliminate visible product defects, sharpen steel cuts and many other functions. Nozzles for a drill for grinding are rods on which abrasive nozzles are located. When the chuck is rotated, it accelerates to the same speed and is used as a grinding wheel. The abrasive can have different grain sizes.
  2. Nozzle for a drill for grinding wood. A similar item as for metal processing, but instead of an abrasive, a polyurethane, rubber, mineral (etc.) circle is installed, with which you can make the surface extremely smooth and without chips or needles.
  3. Nozzle on a drill for polishing. This is a specific tool, the base of which is made of rubber and foam rubber., an emery wheel can be attached to them. This design ensures maximum processing quality. Nothing like a polishing machine. The only drawback is that the drill is much heavier, so it will be a little uncomfortable to hold it.
  4. Grinding sun. Another unusual fitting. It is a circle from which strips of sandpaper come out like rays. When the chuck rotates, the paper petals accelerate to high speed and grind any metal in a few seconds! The nozzle is short-lived, enough for a couple of hours of work, but very effective!

We have reviewed the most useful nozzles. Now the choice is yours: use these devices or buy expensive devices.

The compact nozzle "Cricket" is installed on various powerful electrical appliances - in particular, screwdrivers, drills and rotary hammers. Thanks to the ability to cut sheet metal, it significantly expands their functionality, allowing you to perform more operations with one unit. The use of tool steel for its production makes it possible to ensure maximum strength, and also allows you to work with a wide range materials. In addition, the carefully crafted design results in low noise and mechanical losses.

Performance characteristics

The power of the main device on which this device is installed should not be less than 0.4 kW - with this value, effective cutting is achieved without a strong bend in the metal edge. This indicator corresponds to the parameters of most household power tools - both drills and rotary hammers, and screwdrivers. The length of the device is 180 mm - due to this, it is possible to work not only in ideal workshop conditions, but also in confined spaces. The power take-off is based on a hexagonal shaft, which has good traction and is stronger than traditional round shafts.

Due to the high quality of the tool steel used, the Cricket nozzle can cut rather thick metal sheets. For stainless steel, this figure is 1 mm, and for softer alloys - 1.6 mm. When using aluminum, the thickness can reach 2 mm. Using the nozzle, you can also create round holes with a diameter of 11 mm or more. A feature of the device is also the small width of the cut track - it is only 1.6 mm. This provides a good level of metal savings that cannot be achieved with hand tools.

Peculiarities

The nozzle does not increase the mass of the appliance, since its own weight is only 400 grams. Additional advantages include the presence of a punch and a replaceable handle in the delivery package, with which you can increase the accuracy of the work.

Nozzle-scissors "Cricket" is designed for cutting sheet steel in a straight or curved line, for cutting holes of arbitrary shape from a pre-cut drilled hole 11 mm in diameter. The nozzle is powered by an electric or pneumatic drill.

Cutting is carried out according to the principle of nibbling scissors. The nozzle does not require adjustment, is easy to use and maintain.

It all started with the fact that I was going to change slate roof on a metal tile and sheathe the house with metal siding.

I went and bought everything I thought I needed. I am engaged in construction, but I have never worked with roofs, with painted galvanization either. Zero experience. But hands from where it is necessary to grow.


In general, the slate was removed, everything was prepared, sheets of metal tiles can be fixed. The roof is multi-pitched, a lot of trimming and fitting. As it seemed to me at that time, I would cut with an angle grinder, in the common people with a "grinder", ordinary cutting disc. And after the first attempt, doubt crept in, sparks flew in all directions, stuck to the coating and even burned it in places. It is no longer difficult to guess that at the place where the coating is broken, corrosion will appear very quickly and the meaning of replacing the roof will be irretrievably lost. I tried ordinary metal scissors, it's funny to remember how much time it would take me to go through all the corners, oblique cuts and fittings. Moreover, ordinary scissors are not at all designed for cutting metal tiles.


I started calling my friends. Friends explained to me that there are punching and cutting electric scissors that perfectly cope with such tasks. In the store where I arrived, they showed me a lot various models, everything would be fine, but the price turned out to be very biting. The cheapest 12.000 rubles. What's the point of buying them, what am I going to do with them? In the installation of plumbing and heating, (what I do) they have no use. In short, I was upset and, out of hopelessness, was about to fork out, when suddenly a man who was standing nearby and heard our dialogue with a friend wrote the address of the store and the name "nozzle for a drill" on a piece of paper nibblers for metal "Cricket"


We arrived, twisted, turned, listened to a brief oral instruction manual and bought it. The purchase cost 1250 rubles, that is, ten times cheaper!

In 3 days we covered 200 square meters of roofing and sheathed the house with metal siding. The nozzle exceeded all my expectations. First, put the nozzle on the screwdriver, (1800 rpm) the cutting speed is slow and the quality is not super, burrs, uneven edges, already upset. Then they put it on an electric drill, (3000 revolutions) heaven and earth, the edges are smooth and the speed is completely satisfied. It is convenient to work with an uneven and sharply convex surface, as well as adjust the degree of inclination. The cricket handle is independent of the drill and rotates 360 degrees. Cuts sheet metal up to 1.6 mm like paper. Any hole in the sheet, please enter a 12 mm hole and you're done! I tried to cut two sheets of galvanized 1.0 mm, that is, 2.0 mm at the same time, and it cuts very decently. I also liked that there are two heads on the nozzle, on any of which you can screw the handle, and after it becomes dull, do not immediately change the matrix, but only turn it 90 degrees and change the cutting edge. This is done in three movements, loosen the screw with a special key, turn the matrix, tighten the screw. And in this small, in my opinion, indispensable tool in everyday life, everything is as simple as one, two, three!

Doing construction or repair work, almost everyone is faced with the need to cut any metal blank. To perform this procedure, you can use a grinder, cutter, hand shears for metal.

But what if it is necessary to cut a metal sheet, but there are no such tools at hand? You can solve the problem with an ordinary drill and a special nozzle that you can buy at any hardware store.

What are metal cutting tools?

Such a device, in fact, is a cotter pin or punch, which is a set of repeated movements using a matrix to pierce metal. As a result, a strip of the desired shape and width of 3.1 mm is formed in the cut metal part.

Due to the point effect on the metal, the integrity of the protective layers of the product is preserved to the maximum.

Using the nozzle, you can process material that has a thickness of:

  • aluminum - up to 2 mm;
  • copper, brass, sheet iron, pure zinc and steel coated with zinc - up to 1.5 mm;
  • stainless steel - up to 0.8 mm.

In action cutting tool leads drill chuck, to which it is attached. It is worth noting that the nozzle can cut metal only if the number of revolutions of the drill is at least 2700 rpm.

Nozzle benefits

Compared to a grinder, the drill attachment has a large number of benefits.

However, despite all the advantages of the tool, in order to ensure high cutting quality, it is necessary to work with it. certain dexterity and skills.

Special nozzle "Cricket" on a drill for cutting metal

Hardware stores offer several types of accessories for drills for cutting metal.

Nozzle "Cricket". The "Cricket" device is a cutting (cutting) scissors that are able to perform an even cut. The tool is used for cutting not only smooth, but also profiled metal sheets.

In addition to metal, they can cut plastic and polycarbonate. Cricket is used for cutting sheet products:

  • The maximum thickness of sheet steel should be 1.5 mm.
  • The maximum thickness of stainless steel is 1.2 mm.
  • The maximum thickness of copper and aluminum is 2 mm.
  • The thickness of the plastic is 2 mm.

With the help of the Cricket attachment, you can cut on horizontal and vertical surfaces, as well as make internal cuts. In order for the internal cut to turn out to be of high quality, the workpiece must first be drilled.

The tool is indispensable when performing roofing works, during which it is required processing of metal tiles or corrugated board. After applying Cricket, the materials used will not be deformed, and the cut will turn out to be even and beautiful.

If there is a need to make artistic cutting or drill a large round hole, then the Cricket nozzle is easy to cope with this task.

Nozzle "Steel beaver"

The device is designed for cutting flat and profile sheets (corrugated board, metal tiles). It has a cutting mechanism, the operation of which is similar to the processing of materials with punching shears.

During metalworking with the Steel Beaver tool sparks are not generated and the protective layer of the metal coating is not burned.

Main characteristics:

  • cutting is performed at a drill rotation speed of 1500–3 thousand rpm;
  • the maximum thickness of aluminum and copper sheet should be 2mm;
  • stainless steel sheets must have a thickness of not more than 1.2 mm;
  • the maximum thickness of the steel sheet can be up to 1.8mm;
  • changing the direction and angle of the cut - 360 degrees;
  • the minimum cutting radius is 12 mm.

Models of nozzles for a drill and their application

With special nozzles for drills, you can perform both straight and curved cuts. Do curly cuts for installing gutters drainage system or ventilation parts of the roof, cut in the vertical and horizontal direction.

After using the tool cut is clean. The nozzle does not require adjustment and is easy to maintain.

In the construction market, nozzles for a drill are represented by several models:

  • ACCO YT-160A.
  • EDMA NIBBLEX.
  • Sparky NP 1,8 L.
  • "Cricket" from Enkor manufacturers.

By by and large all models of nozzles for a drill work according to the same parameters. An exception may be the thickness of the metal sheet, which can be cut by a particular tool.

After applying the devices, the edge is obtained sharp, smooth and not wrinkled. It is only necessary to ensure that the speed of the drill used matches the characteristics of the nozzle.

Those who are engaged in construction or repair sometimes need to cut metal. And, if it is not possible to purchase an expensive tool, then the cutting process can be entrusted to a drill with a nozzle.

For home crafters, this tool will become optimal solution and a great helper. It should be borne in mind that the cutting process can be entrusted to specialists who have experience and certain skills.
