Angle grinder attachment for cutting sheet metal

Accessories for angle grinder, different functional purpose, greatly expand the capabilities of the grinder. Allow her to engage in the performance of a variety of works. Provide the value of this device when dealing with various household issues.

PATRIOT AG 122 angle grinder

I propose a list of devices that allow easy, quick and high quality to perform the necessary work without expensive power tools. Well, or just making it easier and safer to use the grinder itself.

Chain saw bracket

This detachable tool will be useful in a private home, cottage, small workshop. Its installation transforms a usual “angle grinder” into an electric saw capable of cutting dried wood or sawing a thick bar. (Cumber can be cut both crosswise and lengthwise).

The chain saw arm can easily be installed on the “angle grinder” and disconnected from it. The saw is designed to be connected to grinders designed to work with 115mm and 125mm diameter discs.

Power of chain saw depends on power of “angle grinder” to which it is connected.

Safety precautions when working with an angle grinder

This question is the most important. Because if you break the rules of operation of the angle grinder can get serious, sometimes life-incompatible injuries. Let’s take a look at the main ones that must be observed.

  • Disc size. Many people think that if you put a large disc on a small angle grinder by removing the protective cover, nothing bad will happen. They say a big angle grinder is more powerful. This is a life-threatening misconception. The fact that the small angle grinder has a much higher speed, and therefore they need different discs. When installing a large disc, the master is likely not even have time to start working. the disc will fly off when switched on, which in the absence of a protective cover will lead to disastrous results.
  • Direction of rotation. Some “craftsmen” do not like the fact that sparks fly under their feet when they work. They unfold the hood, move the handle and start working. This is what most often causes the disk to break when caught on a sharp edge. The angle grinder must rotate the disc “toward you” and not the other way round.
  • Personal protective equipment. Wearing protective goggles or face shield, gloves, mask or respirator is essential. It will save you from burns, eye injuries, which, unfortunately, are not uncommon in such work.

Normal cutting of thin sheet metal

The metal, 1 mm in thickness is not too difficult to cut, but you must be extremely attentive and careful. It is especially when cutting such material that the disc often “jams”. First of all, you must make sure that there are no defects on the cutting plane of the wheel. That is what causes the cutting wheel to fly away.

Thin sheet metal should be cut from the far edge backwards

Start at the farthest edge of the sheet, moving backwards. In this case, it turns out that the master pulls the angle grinder on himself. In this case the disk should not sink deep. a maximum of 5-6 mm. With this type of cutting, it turns out that the cutting wheel simply can not catch on anything. If the disk goes deep, the area of contact with the metal is sharply reduced. This results in jamming, which can cause the cutting wheel to break off.

angle grinder

The most popular tool in the household is the angle grinder. It can also be used to cut metal. To do this, you need to buy the appropriate cutting wheel. They come in different thicknesses. If there is thin sheet metal and precise cutting is necessary, the thinner wheel is better suited. If you need to cut fittings, it is more convenient to do it with a disc of greater thickness.

The main features of working with metal with a sabre saw is the absence of sparks and ease of work in hard-to-reach places. Using this tool produces a smooth and clean cut. But it should be remembered that the saber saw only works in a straight line. This is the main difference between it and a jigsaw. There is a high probability of damaging the cutting blade when bending. It is also important not to overheat the cutting material. You need to work at low speed for this.

Pipe cutter

For cutting steel pipes a special tool. pipe cutter. is the most effective. Its indispensability is that it provides a cutting plane strictly perpendicular to the pipe. The tool is equipped with sharp rollers, which provide the result when the tool rotates around the axis of the pipe. An important feature of using the device is the need for hard fixation of the pipe in the clamping.

Recently various kinds of multi-tools have been actively advertised, one of which is the Renovator. The tool creates oscillating movements of the nozzle with a small amplitude, but a high frequency (up to 22 thousand vibrations per minute). You can also cut metal with this tool. At the same time, the forums agree that the effectiveness of the renovator does not extend to anything other than nails.

Making a long cutting stand for the angle grinder

Get a full-fledged machine for cutting sheet material can be even without an ordinary angle grinder, which I will demonstrate. I made a linear guide, using which you can cut metal, wood, plastic and even ceramic tiles. It is relatively inexpensive to make, takes up little space and is versatile.

Materials spent

First make the roller carriage for the linear guide. As its base will be used profile pipe with a cross section of 20×20 mm. You will need 4 pieces of 300mm long.

Now you need to drill through holes for the future connection of parts. Their centers are located 25 mm from each edge of the profile pipes. A drill bit with a diameter of 11 mm is required.

Having turned the shined profile on the other side, and having already stepped back 50 mm, similar through holes are made on each side. Using a drill bit of 11 mm.To hide the later used in the assembly of the carriage bolts through holes in blanks need to be finished. To do this, one wall of each profile must be drilled, using a drill with a diameter of 17 mm. That’s how all 16 holes are finished, the other 16 are left untouched.

Now you need to make a shoulder to fix the most angle grinder. You will use 40×20 profile pipe 300 mm long.

To be able to further adjust the depth of the passage when sawing requires additional adjustment element. It is made of 20×20 profile pipe. Prepare a 160 mm long piece. Its ends are cut at an angle of 45 degrees. You can cut by eye, since accuracy is not so critical.From a profile tube with a cross section of 15×15 mm you need to cut small spacers length of 40 mm. You will need 8 pcs.

Having finished with these blanks, it’s time to assemble them together. We will use M12 solid threaded bolt 200 mm long as the connecting hinge. On it you need to screw on 3 long nuts M12.Having fixed bolts with nuts by clamps to the table it is necessary to attach preparations of a pair of profiles 20х20 and one 40х20. The pipes need to be welded to the nuts.

From a steel strip width of 40 mm should be cut 2 blanks length 50 mm. Drill a hole with a 11 mm drill bit on the center close to the edge.

The plates should be screwed to the gearbox of angle grinder in the regular holes used to mount the handle. In some tools, these holes can be made for bolts M8, which will need to take into account. For reliability, the clamping bolts M10 40 mm need to be equipped with nuts. The bolts are screwed through the plates into the gearbox and tightened with nuts.

Need to put an angle grinder with plates to the workpiece from a profile of 40×20 mm and weld. After the tool can be removed so as not to harm the already securely welded mount.

By eye backing off a bit from the attachment plates is welded previously made blanks from a profile 20×20 length 160 mm. On its free end plate is welded from the same strip as the mount for the angle grinder. On the protruding ear of the plate we drill a hole and weld a nut M10 on it. To strengthen the construction of an additional steel bar on the side of the profile should be welded to a length of 160 mm, also sawn under 45 degrees.

Now the welding work is complete and you can proceed to the assembly. It’s time to paint parts.

How to cut a thin sheet metal evenly

For quick and accurate execution of work related to cutting sheet metal must properly pick up this power tool as an angle grinder. For cutting thick or thin sheet you need to select the angle grinder appropriate capacity, as well as the diameter of the cutting wheel. In addition, when buying it is recommended to pay attention to the functionality of the power tool (availability of soft start system, disk speed control).

For daily household use, if the need arise to cut thin metal, will fit an ordinary low-power angle grinder (up to 1 kW). However, in order to cut thicker sheets, it is preferable to buy a powerful angle grinder (2 kW and above), which are equipped with a soft start system. There are several types of angle grinders, differing from each other both in scope and functionality. Such power tools can be:

  • professional type;
  • semi-professional type;
  • domestic;
  • with the presence of one or more handles;
  • with soft start system and self-tuning speed control mechanism.

In addition, there are angle grinder of medium, small, and high power. Such an electric tool can be used for cutting metal, as well as other hard surfaces (concrete, stone). The angle grinder is often used to perform a variety of works related to scraping, sanding, and polishing work surfaces.

For cutting sheets of small thicknesses, you can use a low-power angle grinder, the power of which is about 0.6-1 kW, with a disc diameter of 125 mm.

However, such an angle grinder is not recommended for cutting thick metal, as in this case, during the work of the angle grinder will often jam the cutting disk, which is fraught with the possibility of serious injury.

To accurately and evenly cut a thin sheet metal with a thickness of about 1 mm, you need to be extremely careful and attentive. After all, when processing such materials with an angle grinder, the cutting disc can “bite”. Therefore, before carrying out the work, you should inspect the cutting disc and make sure that its surface is free of any defects and chips.

If the integrity of the disk is damaged, then it is not recommended for use in works on cutting products made of metal. Otherwise, a deformed or damaged circle can fly apart during cutting.

To evenly cut a thin sheet metal with an angle grinder, you need to make on its surface to draw a line for the trimmer, along which the cut will be made. Start cutting a sheet from its far edge, gradually moving backwards, in the opposite direction. When using this method, the user will pull the angle grinder in its direction, gradually moving along the sheet to its second edge.

Keep a close eye on the disc when cutting thin sheets. Do not allow it to plunge too deeply into its surface during cutting. The maximum plunge depth should not exceed 5 to 6 mm. This method of cutting eliminates the possibility of a hooked wheel. Otherwise, when the depth of penetration of the cutting disc into the sheet is more than 6 mm, because of the reduced contact area, there is a high probability of snagging.

How to cut thick sheet metal evenly

To cut thick sheet metal, it is advisable to use an angle grinder with a power of more than 1 kW. In this case, cut the workpiece with the angle grinder in the forward direction from its edge. First it is necessary to draw a line on the sheet for the trimmer, along which the cut will be made. Then along the drawn line you need to put a steel angle or flat wooden bar. With the help of clamps, the angle (bar), tightly nestled to the surface of the sheet.

Then along the angle, strictly along the drawn line it is necessary to pass the angle grinder and make a small groove, the depth of which is about 1-2 mm. After completing this procedure, the angle can be removed and begin to cut the metal.

Done on its surface, along the marked line, the groove will not allow the saw blade to depart from the predetermined trajectory, so you get a perfectly smooth edges at the cutting points.

Important! When working with the angle grinder must comply with safety regulations and use personal protective equipment.

Also, during the work, it is necessary to consider the direction of rotation of the wheel of the angle grinder, as well as its size. Do not put on a small angle grinder (125 mm), large discs (150 mm or more), after removing the protective cover.

In the workpieces bore holes for bolts to fasten the angle grinder.

Cut a hole in the sole for the disk of the angle grinder.

Also, we weld another nut on top of the device and screw the handle into it.

We got here such a construction, fix it with bolts to the angle grinder and use.

Now in order to evenly saw off a piece of sheet metal, it is enough to fix the sheet itself and the guide (a flat bar or an angle) with clamps on the table. Press the base of the device to the guide rail and cut the metal.

Simple and handy homemade device for angle grinder.

We suggest watching the video, the author of this homemade machine:

Cutting machine

Cutting machine is used for cutting and cutting metal and profiles, getting equal-sized workpieces, cutting to a certain depth, cutting ceramic tiles, etc. д. In the trade network you can buy a ready-made design, which costs a lot of money. Make a device that will perform the same functions in homes and small shops, you can out of the angle grinder power of 0.9 kW.

In the figure you can see that in order to make such a device, you only need to think through the design and reliable fixation of the angle grinder. To do this, you must first determine the dimensions and fix them at 2-3 points, so that during the cutting process the tool does not move. And this is very important.

the angle grinder can also be located from below the table top. In this case, it will not only cut different materials into pieces, but also work as a circular saw.

Ceramic grinder

Cutting porcelain tile with an angle grinder requires skill and knowledge of the structure of the material, t. к. it is difficult to hold a straight line for the trimmer, holding the tool in your hands. The work requires a special approach: it is necessary to ensure the movement without deviations and to control the depth of cut during the operation. Any violation leads to damage to the material, the appearance of chips and irregularities. This leads to additional costs, and it costs porcelain tile is not cheap. In order for the angle grinder to move without deviation, you can make a special fixture, where there would be guides. The figure shows a variant of making such a device, where the main material is plywood and fasteners.

Before making, for example, any machine using an angle grinder (the device is quite simple), it is recommended to get acquainted with the drawings-schemes, which can be found on the Internet or in special literature. They will help to better understand the principle of the device themselves, as well as how to make various attachments that may be required. Nodes will have to pick up empirically, focusing on the actual dimensions that are available in this particular model of the turbine. Such a machine can be ideal for cutting and facing different workpieces.

There are dozens of different nozzles, which can be of very different sizes, so you should pick up the parameters of the working elements, when you have in front of you this particular model.

Creation of a machine for sawing wood

From the angle cut two pieces (45×45 mm). exact dimensions are to be seen from the dimensions of the gear unit of the angle grinder. In the corners are drilled holes of 12 mm (to which the angle grinder is screwed). If the factory bolts are too long, they can then be cut. Sometimes studs are used instead of bolt fasteners, it does not affect the quality of the connection. Often angles are welded, such fastening is most reliable.

A special support for the lever is made, the unit is mounted on it, it is necessary for this purpose to find two pieces of pipe, so that they fit with a small gap one into the other. And to make the marking more accurate, it is recommended to wrap the fragments with adhesive mounting tape, with a marker to draw the lines. A cut is made along the line, the element of the pipe with a smaller diameter should be smaller (1.8 cm). For the inner diameter, you will need to find two bearings, which are inserted into the more massive pipe, then a smaller diameter pipe is inserted into the larger diameter pipe. The bearings are pressed in on both sides.

In the bearing is placed a mount, it is necessary to put a counterwasher in the bolt mount. After you have prepared the swivel assembly, you should fix a small piece of angle.

Vertical mounting for the swivel knot is made from 50×50 mm angle, the sections should be of equal size. Angles are fixed with a clamp and cut.

It is recommended to drill the angles at once, and then they with drilled holes can be attached to the swivel unit using nuts.

Now you should figure out how long you will need a lever. it will be used to mount the angle grinder. Performed similar action on the technology of selection, and should take into account the parameters of the turbine. Often the parts are first laid out on a flat plane and analyzed, then the configuration and size of the product becomes clear. The pipe is most often used square with a size of 18×18 mm.

After all the components have been precisely fitted, they can be welded together.

The pendulum assembly is easy to place on any plane. It can be a wooden table, which is clad with a metal sheet. A more rigid attachment is provided by welding two small pieces in which holes are drilled.

Chain saw attachment

It will help modify power tools and will be indispensable for professional repairmen and builders.

Benzopil of angle grinder

Made of quality and durable materials, the “chain saw” attachment is durable and resistant to wear. It is suitable for quickly cutting wood, and allows you to work with a variety of materials. With its help you can:

Machine for cutting sheet steel

Angle grinder for cutting sheet metal

For cutting sheet steel, long sheets of textolite, chipboard with an angle grinder requires a different design. In this case the angle grinder must be able to move along the workpiece. This is made possible by fastening the angle grinder to the sliding carriage.

The carriage can be made on the basis of roller door blocks. Angles or small channels are used as guides. They are welded strictly parallel to the base plate. Instead of welding, a screw connection to the platform is possible, but the screws must be countersunk and the nuts secured with Grover washers or locknuts.

The angle grinder can be mounted directly on the carriage rigidly or on a pendulum lever. The guides must be set so that there is a gap between them and the work table to position the material to be cut on the table.

How to properly cut metal with an angle grinder

Below we will tell you how to properly cut with an angle grinder sheet metal and other forms of workpieces. There are a few basic recommendations.

  • Keep an eye on wear of the cutting part. The diameter of the blade determines how deep it will go into the workpiece. When grinding wheel is worn out, replace it in time.
  • The rotary axis becomes excessively hot at high speeds, so keep it well moistened. Cutting tool achieves higher productivity after cooling.
  • How fast you can cut metal with the angle grinder depends on the tool’s rated capacity. Do not overclock the blade, because this causes a rapid wear. Optimal parameter. about one-third of the limit values.
  • Hold the angle grinder when cutting metal necessary so that the drive went perpendicular to the workpiece. Do not apply pressure to the body. the movements should be gentle.

Expert recommendations for some applications

Below we will tell you how to work with an angle grinder on various metal products.

Chainsaw chain sharpening

Picture 2: chain saw chain sharpening with an angle grinder

The chain is being sharpened on the chain saw arm. Use a 2,5 mm thick sharpening blade for the work. You need to mark the first tooth that you will work. If you do it right, you can renew the chain four to seven times before it finally fails.

Cutting pipe

Start cutting thick metal with the angle grinder from the edges. If you start in the middle part, the disc can jam and bend. During processing, apply force to the lower part of the cutting tool, which ensures the efficiency of the cut.

Cutting moldings

Photo 4: Cutting corners with angle grinder

For cutting metal angles you can use worn discs or small-diameter tools. It is important to remember that the work is staged: first cut one part of the molding, then. the second.

Circular saw wheel sharpening

Picture 5: Grinding circular saw blade with angle grinder

Start by clamping the angle grinder with clamps, leaving the rotating part of the tool accessible. Then bring the saw blade close to the sharpening wheel, making sure not to force it. The wheel must run tangentially along the workpiece. Keep an eye on the sharpening plane when working.

Polishing is a complex operation of finishing workpiece. Eliminate minor defects such as scuffs, chips, and scratches with it. The surface acquires a noble shine and the product acquires a saleable appearance.

Cutters with indexable inserts are compound metal cutting tools that contain removable work pieces that are clamped onto the body of the tool. The products are used to form grooves, inclined surfaces and ledges. It is used to prepare holes and create complex technological cutouts.

Cutting grooves and ledges involves complex operations on several surfaces at the same time. Actions are performed with the use of profile milling cutters, provide preparation of technological ledges and openings for subsequent connection of parts.

Cutter wear is a complex phenomenon that occurs as a result of tool operation. As a result of wear and tear, the sharpness of the cutting edges is impaired and the weight, geometry and mechanical stability of the product are impaired.

Calculation of cutting regimes is carried out for mechanized and manual metal processing. Based on the results of the calculations, tooling is selected, the optimal method of work and the amount of production costs are determined.
