Nozzle on the drill for cutting metal
Universal metal shears. cricket drill attachment
In the manufacture of structures made of metal tiles is very necessary to correct the shape of the material, namely, cutting.
to use such a tool as a drill. But that’s just the gear. The drill bit for cutting metal sheets plays the main role.
Only its specifications will determine the quality of cutting the material.
In case of poor performance of correction, the product of metal will have an unaesthetic appearance.
It is a detachable mechanism that is mounted on a standard chuck of an electric hand drill. Designed for cutting flat and corrugated sheet metal:
- Composite aluminum sheet up to 2 millimeters thick
- Galvanized profiled sheet metal up to 0.8 mm thick
- Copper, brass up to 1.5 mm thick
In appearance, the cricket drill head resembles a cylindrical steel billet, with “fingers” sticking out on both sides. The cylindrical bolt is the body through which the torque is transmitted from the drill to the two cutting surfaces. “Fingers” are paired dies that contact directly with the metal workpiece. Included with tool is a plastic threaded handle-holder, which screws on one of twin cutting surfaces.
In addition, a spare die and punch as well as a hexagonal wrench are supplied with the nozzle.
Drill bit for cutting sheet metal: the scope of application
The main purpose of such an accessory is the machining of metal workpieces, mainly sheet iron. The variety of options and types available on the market makes it possible, with proper practice, to produce not only straight cuts, but also shaped cuts, which happens to be necessary at:
When choosing a particular type, it is necessary to determine the front of the future work. Tools for cutting round holes, which resemble a milling machine in the principle of operation, are available for sale. Also with the use of the nozzle you can get devices for grinding metal, which is important when it is necessary to treat edges or seams, especially after welding or cutting work.
All models of devices on the market are divided into certain types according to their application. They can be:
- to carry out angular drilling;
- Performing grinding work;
- for drilling;
- allowing you to polish the surface;
- used for sharpening;
- used directly for cutting.
The difference of accessories to the power tools for metal cutting consists not so much in the features of functionality, as in the allowable thickness of the processed sheet, which must also be considered when choosing the best option.
Drill bits for cutting profiled sheeting. design and features of work
All available models inherently their work is a splint (punch). An internal plunger that makes several reciprocating movements pierces the metal. Such a device provides an opportunity to create a strip in the workpiece, which has the desired size and shape.
The nozzle itself has a long enough shank, which must be fixed in the chuck of the hand-held power tool. It is fixed by means of nuts that hold in a normal state, a drill bit or a bit. Clamping part has a rounded shape, which simplifies the process of turning the device at the necessary angle for the work.
Through the use of this accessory, the user is able to process the following materials:
- Aluminum sheets up to 2 mm thick;
- stainless steel, which has this parameter up to 0.8 mm;
- iron, copper, brass or galvanized sheets with a thickness not exceeding 1.5 mm.
It is worth noting that to cut metal workpieces with a special nozzle is recommended only when providing a rotation speed of at least 2700 rpm.
What are the attachments for metal cutting drills?
Equipped with a special attachment for metal cutting an ordinary drill turns into a punch or splint. The device pierces the metal workpiece by performing numerous reciprocating movements on the inner cavity of the die. The result is an even line for the trimmer cutting width of 3.1 mm with preservation of the protective layer on the surface of the sheet metal.
Important! Maximum effectiveness of the nozzle is achieved only when working in conjunction with an electric drill, the chuck speed is not less than 2700 rpm.
In order to cut a metal sheet with a drill, you need to use a specially designed for this scissor attachment
The metal cutting attachment on the drill can cope with the cutting of such metal products:
- Aluminum, up to 2 mm thick;
- made of brass, copper, zinc, galvanized steel and sheet iron up to 1.5 mm thick;
- made of stainless steel, up to 0,8 mm thick.
There are a number of advantages to using the metal cutting attachment on your drill:
- the cut is of high quality;
- there is no need to constantly buy consumables, which saves money;
- It provides a high productivity when cutting metal;
- the universality of the device;
- The equipment is convenient and easy to use and maintain;
- the nozzle can be used in electric and pneumatic drills;
- It is possible to make cuts in any shape with the nozzle.
the upper cutting part of the nozzle moves up and down, thus cutting the metal and pushing its particles into the slot
Despite all of the above advantages, to get a high quality cut, you need some skills and dexterity.
Popular nozzle models
Today there are many different models of nozzles for the drill, through which you can perform not only cutting metal in a straight line, but also to make shaped cuts. This is necessary when performing the installation of ventilation ducts, roof structures, gutters. Any spatial position is possible with the attachment, without having to make any adjustments.
- Steel bobber” punching nozzle is used to cut steel tiles, corrugated sheeting and any flat profiled sheets;
- universal nozzle “Cricket” is used for cutting profile metal, polycarbonate and plastic;
- Special nozzles for making curved and curvilinear cuts are represented by models EDMA Nibbek, ACRO YT-160 A, Sparky NP 1,8 L, which differ in the thickness of the processed sheet.
The cutting mechanism of the EDMA drill bit is based on the guillotine principle, cutting without shavings
Steel Beaver Drill Bit
Classic nozzle on the drill for cutting steel tiles and any flat sheets of metal in a free rotating shaft in a bearing with an eccentric fixed works on the principle of the crank mechanism with the difference that the energy is supplied for rotation.
Cutting tool with a complete cutting tool has a supporting part on the base and a movable part connected to the eccentric. It is the moving part that reciprocates as the shaft rotates. The indispensable element of the construction is the handle, which is fixed perpendicular to the axis of rotation of the spindle. When the load is increased, there is a reaction torque that causes the drill to move relative to the nozzle.
Keep in mind that the tool must be held vertically in relation to the workpiece when making cuts. Failure to do so can result in damage to the product and injury to the operator.
The device resembles a metal scissor. Drill attachment is used for cutting flat workpieces or profiled sheets with large radius curves. cutting line for trimmer is easy to control. During tool operation the protective layer of coating is not burned, what excludes sparks and possibility of burr formation. All lengths of workpieces can be cut in a continuous fashion.

Using the nozzle “Steel Beaver” for a drill, you can make a shaped cutout for installation of ventilation elements of the roof or gutters
Cutting of the sheet is performed at a speed of the drill 1500-3000 rpm. Cutting angle is 360 degrees, the minimum radius. 12 mm. The “Steel Beaver” attachment can be used for cutting:
Useful tip! For cutting profiled sheet metal with small bends in diameter should use prosechnyh scissors type “Cricket.
Drill bit “Cricket”
The “Cricket” cutter scissors got their name due to the characteristic noise during operation of the device. This nozzle is similar to the previous model, but has a different design of the working element, which consists of two cutting heads. The principle of operation of the nozzle “Cricket” is similar to the office perforator. Accurate holes in metal are squeezed out with high frequency during the oscillatory motion of the cylindrical beater. Thanks to the translational motion along the marked line it is possible to obtain a straight cut.
The scissor bit “Cricket” is designed for straight and curved cutting of sheet metal
Scissor-cutter head “Cricket” is used for cutting thin metal and profile sheets, and thin sheet plastic products up to 2 mm thick. Work can be performed both horizontally and vertically. Thanks to the tool’s ability to rotate 360 degrees, it is possible to drill large, circular holes. It is possible to drill large round holes and make artistic cuts. Buy the nozzle on the drill for cutting metal “Cricket” can be on average for 1500-4000
The tool can cut metal with ribs and various profile embossings in two ways. The first option involves repeating the surface of the profile, skirting the edges. Used for products with an average bending radius. For cutting metal tiles another version is used, according to which the tool moves along the ribs without enveloping the profile of the sheet.
Drill bit sharpening attachment
This unit consists of a plastic body inside which a specially shaped emery wheel rotates. It is he who allows you to form the desired angle of sharpening on the working part of the tool. The wheel is mounted on the shaft, which is connected to the drill by a special coupling. It is activated when the tool is switched on.
Many modern models have an end cap on the housing, which has holes of different diameters for sharpening drills of different sizes. These holes are designed in such a way that the sharpening block contacts the emery wheel in a defined position.
The principle of operation of the nozzle for sharpening drills is simple. when you turn on the drill chuck rotates the sharpening stone located inside
The process of sharpening a drill bit is as follows. The product is inserted with the cutting part in the hole of the nozzle of appropriate diameter. After starting the drill, the emery wheel begins to rotate, sharpening half of the drill bit. Next, the product is inverted in the hole by 180 degrees, and the procedure is repeated. This sequence of actions is carried out several times until the required parameters of the cutting part of the drill bit are achieved.
Drill bit sharpening attachment, which you can buy for an average of 350-500. has 15 holes with diameters from 3.5 to 10 mm. Products can be turned at 180 degrees because of the special shape of the stone. The machine’s simple design allows you to work quickly and without special skills.

Remember, however, that the device is designed for sharpening undercut cutting edges. For a complete sharpening of severely worn products, the grinding wheel will not last long.
Useful tip! Buying a particular model of nozzle, you should consider the diameter of the drill chuck.
There is also another type of attachment. This is the nozzle on the drill for sharpening knives and scissors, which is represented in the form of two abrasive wheels, planted on the shaft and located at a certain distance from each other. The price of such a device is about 250
The nozzle for sharpening knives and scissors for a drill is easy to use, does not require special skills in its use
Designs and how they work
The principle of operation of the nozzles used for metal cutting is to convert the rotational motion of the electric motor shaft into translational motion of the cutting mechanism.
Drill bits for metal cutting are fastened in the chuck and actuated by means of the start button (key) of the tool used.
When using metal cutting accessories the rotational speed of your drill (or screwdriver) should be at least 1,500 rpm, otherwise the quality of cut is reduced and it is possible that the material that is cut gets jammed.
In devices of “Cricket” and “Steel Beaver” type, the operation of the cutting mechanism is similar to the principle of the office perforator: when a thin bead pierces holes of small diameter along the entire length of the cut surface. The manmade force of the scissor blade provides progressive movement along the cutting line.
In the jigsaw-type attachment, the cutting blade moves back and forth while the force on the cutting point is exerted by a person.
The principle of the scissor-type attachments is similar to that of simple scissors, the only difference being that in the attachments one of the cutting blades can be rigidly fixed and only the other blade is movable.
- body. which is the base of the construction, where the cutting parts and the mechanism for converting the rotary motion into translational motion (reducer) are located;
- The cutting elements. the blade, flail, or knives;
- the shank. which is the connecting element between the gearbox and the chuck of the drill (screwdriver);
- nodes and components that ensure ease of operation (handles) and reliability of attachment (fasteners). This may or may not be the case with the various machines.
Main advantages of the nozzles
As a rule, experts identify several main advantageous differences between the attachments for the drill and the angle grinder:
- versatility of the tool;
- easy maintenance and use;
- high cutting quality;
- good performance;
- the possibility of making holes of any shape;
- cost savings due to the lack of the need for additional consumables in the work;
- Ease of use of the equipment, achieved by equipping with a special handle;
- possibility of using a pneumatic or electric drill.
We should also not forget that in order to ensure a high quality of the cut, certain skills are needed. Of course, unlike household or professional tools of complex configuration, you will not have to adapt for a long time to work with the nozzle. Any beginner can cut through up to 10 meters of metal in an hour. The attachment can be attached to any type of modern drill.
In general, do not think that the nozzle on the drill for metal cutting will be a full-fledged replacement for several tools at the same time. Unfortunately, the power of this equipment is not always enough in comparison with electric scissors professional level. In addition, the supported thickness of 1.5 mm does not allow for any really serious work.
If you do not consider the output level of the tool, it is possible to buy the attachment for not too demanding work. In these situations, the nozzle will save a lot of time and money.
Review: The nozzle on the drill cutters for metal Enkor “Cricket. They say you need a third hand when working. You need to include your brain, it will work, both.
Good day to you all. Fishing on the Internet recently “came across” a review on the cutting nozzle “Enkor”. I was a little confused by the phrase: You need to have a third hand for normal work. I fundamentally disagree with this statement.About three years ago had to do roofing. Although I have considerable knowledge and experience in this field of construction, but I try to avoid it if possible (for several reasons).
But circumstances were such that I still had to take it.The roof was. metal shingles. Few people know that it is absolutely impossible to cut it with an angle grinder.A hot spark burns the protective layer and violates the integrity of the material, which leads to a lot of trouble afterwards.As I said, the roof is not mine and therefore buy electric shears for metal, throwing 15. 20 thousand really did not want to.I did a search on the internet and happened to see an answer to the nozzles. Looked through the information, punched in the possibility of buying in Bataisk. The store “Enkor” gave it out.I went to the store and bought it. It’s only 1300.
The principle of operation was quite simple. The hexagonal part is inserted into the head of the drill and tightly clamped.
With other punching parts (punches) you can cut the metal.Since there are two cutting attachments on the head, which have a direction in opposite directions, it is possible to work in different directions, which greatly simplifies the work.
Can cut metal, both straight and radial plane.It is also possible to cut holes. It is enough to drill with a drill bit 12 mm, this is enough and forward, the punch is enough.Profiled sheeting is generally no problem to cut, with metal, however, you need a little skill.
There is one more drawback, but it is, in principle, unavoidable when working with these types of tools.This is a crescent-shaped die cut, which gathers quite a bit when working.It can be swept away with a moklovitsev, or removed, with a magnet.And now for the “third” hand. When cutting metal tile length of 4 meters or more, you can not “sweat” at all. The mass does not allow the sheet to wiggle.If less, it’s not a problem either. All the same. I personally used to put a board underneath, for convenience when cutting and not really “bothering” to put pressure on the metal with my knee.The third hand was just not needed.In any case, yes, if you are professionally involved in metal cutting, of course, it’s better to buy a specialized tool, and it’s silly to deny it.But in a case like mine, (and they are not uncommon) can get along with the above option and it will be optimal.
Why not an angle grinder?
If you carefully read the instructions to the metal and its installation, then, of course, you will find a paragraph that says that the cutting of angle grinder is prohibited. The warranty on the product in this case is simply void. Why is that?
Metal from above protected by a special polymer that does not tolerate high temperatures. And when using an angle grinder metal will be heated to just those critical temperatures, so that in certain places to melt and the zinc coating, and the polymer layer. The result. deformation of protective layers, such tiles will be damaged by rust and can even leak.
In addition, sparks from the contact of the abrasive disc and shingles will fly in different directions, forming damage. These points will become small, and later more dangerous islands of corrosion.
Tip: If you decide to cut with an angle grinder, then try to protect the tile sheets from sparks. And the cut areas should be covered with paint for facades. It’s not the best, but it’s bearable.
The nozzle on the drill for cutting metal. cutters
Every man who likes to do everything with his own hands has a paint stripper in his kit. It is this simple device can cope with cutting metal if you buy it as an accessory: a nozzle on the drill for cutting metal.
It is essentially a splint or punch that pierces the metal with multiple repetitive motions thanks to the die. By means of this in the treated metal is formed by the band of the shape you need. The impact on the metal point, the maximum preservation of the integrity of the protective layers of metal. The width of the kerf is 3.1 mm.
Such a nozzle is also called a punching or die-cutting shears for metal. Of course, it does not work as scissors, unlike electric scissors with two blades, but it works on the piercing principle.
Nozzle scissors for a drill is represented in the market several models from different manufacturers:
With the help of the nozzle it is possible to process metals with the following parameters:
That is, the softer the base, the thicker it can be, so it can be cut with a drill with such a nozzle. In principle, all models of this attachment operate according to approximately the same parameters with respect to metal thicknesses, perhaps with some exceptions. Edge, which forms a nozzle is not crumpled, but accurate and sharp. You just need to choose the right speed on the drive of the drill itself.
Very easy to cut round and any shape cuts using such mechanism, thanks to the punching punch. With the same method you will also cut venting accessories for roofing.
To work with a nozzle on the drill for cutting metal tiles need a little bit of skill, but you will quickly learn it. The nozzle is attached to the chuck of the drill, which starts it in the work. Electro-mechanical punching shears work in the same way.
How the “steel beaver” nozzle works
Such a nozzle on a regular drill is also called “cricket”. Suitable for virtually any drill with a rotational speed greater than 2,500 rpm./min. The top part of the nozzle is movable, and it provides a smooth cut without bending the metal. As for the thickness of the metal, it all depends on the material.
What is good about this kind of attachment in work
The main thing that attracts home masters in this nozzle is a significant saving of time and money. For example, when using an angle grinder in addition to damage the protective coating of the profiled sheet also have to spend money on cutting discs. If the amount of such work is large, the costs will be large. Not to mention the fact that the angle grinder is a very dangerous tool in the work. If you do not comply with safety precautions when working with it, you can lose not only your health but also life. “Cricket” is safer and does not require the purchase of consumables.
When working with the nozzle there is no risk of deformation of the sheet, regardless of its shape and cutting line. The edges are obtained neat and smooth.
Thanks to the additional handle on the nozzle, the tool is easy to hold, which, together with the increased working speed, can be called a guarantee that the craftsman will not get tired.
When choosing what to cut metal tiles, you can resort to the nozzle on the drill, which is an addition to the usual drill.
Working principle is similar to electric shears. punch cuts a certain piece of material with every move of the tool.
To use the tool it is necessary to have the skills to work with construction tools, otherwise during the cutting can be difficult.
Saws or an electric jigsaw
The cheapest and time-tested tool is a hand saw for metal. It does not need any special skills and is available practically in every home. But at the same time, the saw does not allow to perform curved cuts, for this you need to resort to advanced tools.
The electric jigsaw makes no less quality moves than the punching scissors, but it will require more time. Jigsaws with special attachments allow you to cut any profiled metal sheets.
Interesting to know that the first mechanical metal shears were designed to install ventilation ducts and systems. The tool has been fundamentally improved over the years and is now also used for roofing work.
