The cover for an angle grinder with dust extraction with your own hands

Ways to make a hood for an angle grinder for a vacuum cleaner with your own hands

When cutting metal with an angle grinder, sparks occur, and when processing concrete, stone, granite, and other similar materials, dust is generated. If the angle grinder to cut the wood, then in the course of the work there is a large amount of shavings. In order to process concrete and wood with an angle grinder performed with minimal clogging, you need to make a cover for the angle grinder under the vacuum cleaner. Such an attachment for cutting power tools can be bought, but to avoid the costs will help to independently make the device.

Before you start working on concrete and wood, you need to imagine what the result will be. When cutting with an angle grinder dust is generated, which is not only deposited in the room, but also falls into the respiratory organs of the person. That is why you should perform work with the tool only in a respirator and safety goggles. To protect the room from excessive dust, you will need to work with a special nozzle, which is connected to the hose from the vacuum cleaner.

Apply the nozzle on the angle grinder should be in the following cases:

  • Cutting concrete, brick, cinder block, slate, and other similar materials. If the shaping is performed at the stage of construction, then the settling of dust in the room is not as dangerous as when carrying out repairs. When cutting tough materials, they are crushed, which causes dust to be deposited all over the room
  • Cutting tiles and ceramic tile. when processing these materials also generates dust, which is especially dangerous for human health. Tiles can be cut with special tile cutters, and no dust is generated, but if the work is performed with an angle grinder, it is better to install a special attachment
  • Wood processing. when sawing wood, not only dust is formed, but also sawdust, which can be easily and quickly eliminated by using the hood installed on the angle grinder

Manufacturers make special hoods for angle grinder with disc diameters of 125, 150 and 230 mm. These are the most common types of cutting tools, so it is under them that manufacturers produce special hoods for dust extraction.

This is interesting!If you do not have an industrial vacuum cleaner, it is not recommended to use a household vacuum cleaner for dust extraction when working with an angle grinder.

The fact that the hood on the angle grinder is necessary, masters and experts do not even doubt it, because it is enough to try once to make a cut of concrete, to be convinced of the need to purchase or make a dust collector. What is better, to buy or make your own hands a cover for dust collection on the angle grinder, here everyone should decide for themselves. After all, the protective cover is relatively inexpensive, but in order to avoid costs at all, then the nozzle should be made independently.

Causes of dust formation

angle grinder is a universal tool. With its help, using a variety of nozzles, you can cut metal, stone, porcelain tile and tile, handle wood and other materials. But one disadvantage is the formation of a huge amount of dust. Work that generates large amounts of fine debris:

  • Grooving in walls. The work is performed on plaster, and the cement and sand have a fine fraction. The height of the channels is at one and a half or two meters. From this height, the dust settles evenly over the entire area of the room.
  • Grinding of wooden constructions. Before painting or varnishing, woodwork is subject to the mandatory removal of pulp fibers that are generated during the sawing process. The pulp is thin, lightweight and hangs in the air for a long time.
  • Remove old paint coatings. Before applying fresh paint, the old paint must be removed. A petal sanding disc is used. The paint it removes turns out to be fine.
  • Cutting of floor and decorative ceramic tiles. Sintered ceramic has a fine grain structure and it penetrates everywhere.
  • Scraping parquet or wood floors. Floors are levelled by removing the top layer. Roughnesses vary in height, so there is a lot of wood dust and swarf.

At the end of the repair, dust has to be removed from all possible cracks and cavities. To protect neighboring rooms from construction dust, protective screens made of polyethylene film or light fabric are installed in doorways. Also special appliances are used, which you can make yourself.

Cutting ceramic tiles without dust

Carry out cutting ceramic tiles angle grinder with a factory dust extractor is very difficult, because the cover overlaps the place of cutting, and the builder needs absolute control over the work. For this purpose it is worth to make a homemade dust canister from transparent materials, for example, from a large plastic bottle.

This fixture is secured with a factory-applied protective cover. The neck of the bottle fits very well under the nozzle of a household vacuum cleaner. Such a homemade transparent nozzle will help to perform the most difficult work. Also the master will be able to control the penetration of the cutting disc into the ceramic tile. At the end of the work it is only necessary to throw out the trash from the bag.

During repair or construction it is sometimes necessary to carry out work on concrete: to cut an opening for a window, an alcove, ream the walls for wiring. Masters know how many small particles are formed in this process. Cleaning up after such events is a very time-consuming activity. We propose to understand, whether it is possible to cut concrete without dust and how to organize this process.

Types of housings

In stores selling power tools you can find a protective cover for angle grinder with dust extraction. Most manufacturers make them for semi-professional and professional equipment of well-known companies.

The purpose of this additional equipment is an effective dust extraction from the processing zone by the angle grinder itself. Fixing is carried out on the regular places with a clamp.

The exhaust outlet is the same size as the vacuum cleaner’s suction hose. Outer diameter is 65 mm. Diameter of the hole is 59 mm. The dimensions of the dust extraction system correspond to the grinding wheel to be installed. For example, the Messer shroud 10-40-441 is designed for a 180 mm diameter wheel. And its dimensions are 245x230x100 mm.

The big disadvantage of purchased equipment is its high price. Thus, the minimum, which is comparable with the cost of budget angular grinder.

But the last resort is a clever trick, and home masters have solved the problem by independently making additional equipment.

Construction of the device

With dust extraction from the pan

When it is possible to find an old aluminum pan, you can make a dust collector without using a welding machine. The main part of the cover is cut out and fit well to the angle grinder. Doing this work, it is necessary to accurately calculate in advance the maximum depth of penetration of the cutting disc, because the height of the cross-cut from below depends directly on this.

From another part of the aluminum pan, cut out a seat for attachment to the angle grinder. Try on the diameter of the hole directly on the power tool. The size of the vacuum cleaner must be as accurate as possible, so that the cover cannot come off due to strong vibrations during the work.

cover, angle, grinder, dust

In the same way it is necessary to make a spigot for the vacuum cleaner. The protruding edges of the cover must be bent inwards as carefully as possible in a single line to fasten the side wall, which can be made of any kind of material. For example, the wall can easily be made out of thin sheet metal. If there is a desire, it is worth to give the device a more aesthetic appearance, treat the joints and paint enamel.

From a plastic canister

The following is another economical solution for dust extraction. Any person can find an empty plastic container from various technical liquids in the pantry. This container holds its shape very well and is quite easy to handle. Also, such a container has a convenient outlet pipe of the required size.

First, a fitting is made, the main purpose of which is to ensure the necessary depth of the cutting disc plunge. Use a construction knife to cut the necessary through holes. Their diameters are chosen so that the homemade structure retains its rigidity. You should make special seating on both sides. This will make it possible to change the direction of rotation of the cutting disc.

Next, the hose of the vacuum cleaner should be connected to the neck of the canister and fastened well with a metal clamp. Secure attachment of the hood to the angle grinder is carried out with the help of the adapter ring and metal clamp. The assembly of this unit should be handled very responsibly. The second hole must be sealed with a cover. When changing the direction of rotation of the cutting disc, the cover is transferred to the other side of the canister.

Such devices, made by their own hands, have a low cost, but the benefits of them are very large. Vacuum cleaner complete with an angle grinder will help to perform almost any type of work in the rooms with the least amount of dust emissions. To scrape wood, you need a slightly different shape of the nozzle on the angle grinder. However, it does not differ much from the products described above. It can be made in the same way, using almost any material.

Purpose of the hood

The most dusty works are considered to be those that are performed in closed rooms:

  • Drilling in concrete and brick. Large amounts of dust are generated regardless of the type of material. This work is complicated by the fact that it is often carried out at a height of up to two meters. Dust falling from the top of a thick layer settles all over the closed room.
  • Tile cutting. This is the most common job done by do-it-yourselfers. Ceramic dust is the most penetrating, fine and dangerous to health.
  • Sanding wood floors. This work is very extensive and is performed on a huge area. For this reason, sawdust and fine dust from sanding produce quite a lot of.

To combat the formation of dust, manufacturers of bolsters offer factory protection solutions. For example, you can install a small dust bag on the angle grinder. However, this solution is suitable for large construction teams. This article will tell you what to do the average home handyman, who will only use an angle grinder.

If financial situation allows, you can buy a special cover in a construction store with a dust outlet, or purchase an angle grinder, which comes with such a device. The high price of such a tool makes the purchase unreasonable for one-time use, because it is much more profitable to invite a team of builders. But there is another way out of this situation.

You can make an angle grinder with a dust collector under the dust collector with your own hands. You can find a lot of variants of this versatile dust collector on the web. Some craftsmen make the hood from durable metal with a welding machine. But there are simpler solutions to this problem.

Make a dust extraction with your own hands can be made of such materials:

Purpose of the hood

The most dusty jobs are those that are performed in enclosed spaces:

  • Shaving concrete and brick. A large amount of dust is formed regardless of the type of material. This work is complicated by the fact that it is often performed with a stroboretzor at a height of up to two meters. The dust that falls from the top settles thickly all over the closed room.
  • Tile cutting. This is the most common job of home builders. It is worth noting that ceramic dust is the most penetrating, fine and dangerous to health.
  • Sanding wood floors. This work is very extensive and is performed on a huge area. For this reason, sawdust and fine dust as a result of sanding produces quite a large amount of.

To combat the formation of dust, manufacturers of bolt-on grinders offer factory protection solutions. For example, you can install a small dust bag on the angle grinder. However, such a solution is suitable for large construction crews. This article will tell you what to do the average home handyman, who will only use an angle grinder.

If the financial situation allows, you can buy a special hood with a dust outlet in a construction store, or buy an angle grinder, which is equipped with such a device. The high price of such a tool makes the purchase impractical for one-time use, because it is much more profitable to invite a team of builders. But there is another way out of this situation.

You can make an angle grinder with a dust cover under the vacuum cleaner with your own hands. In the network you can find a lot of options for this universal dust collector. Some craftsmen make a hood of durable metal with a welding machine. But there are simpler solutions to this problem.

Make a dust collector with your own hands can be made from such materials:

How to make with your own hands a cover under the vacuum cleaner

The angle grinder with integrated vacuum cleaner allows you to get rid of small particles of material formed during cutting with the angle grinder. But what to do if there is a need to saw concrete with an ordinary tool without additional options? The easiest solution would be to buy a cover for the vacuum cleaner separately or make a device with their own hands. It is possible to involve an assistant, who will collect the particles formed during sawing with a vacuum cleaner.

It is easy to make a convenient attachment from a simple plastic canister, which is often sold as auto “antifreeze”. The work requires a construction cutter and a container of the appropriate size, the nozzle of which corresponds to the diameter of the hose of the vacuum cleaner.

The sequence of manufacturing is as follows:

  • Seating holes are cut on both sides so that you can easily reverse the direction of rotation of the disc.
  • A cut of suitable size is made under the wheel.
  • Another hole is cut out for the angle grinder attachment.
  • Connect the hose to the neck of the canister and secure with an adapter ring with a clamp.
  • “angle grinder” is laid in the casing and connect all the elements.
  • Cover the opening that is not in use.

A simple five-liter polyethylene bottle also makes a good dust collector. It is fastened with the standard safety cover and the suction tube to the vacuum cleaner’s neck. Such a design is suitable for any type of work, with the exception of grinding.

Last tip: in order to make the cut evenly, first apply a marking. Then wooden blocks are fastened along the line. Then a shallow cut of up to 1 cm is made, the stops are removed and the work continues. Coolant is applied to the disc blade during the entire process. All operations must be performed in protective goggles, respirator and gloves.

Self-made

Make a cover for the angle grinder under the vacuum cleaner with your own hands is not difficult. You only need to approach the problem with imagination. There are many materials for manufacturing:

The optimal solution is the one that does not require the use of a welding machine.

Standard dust cover

A less costly way to make it is to use the standard. Only attach the side cover and the socket to it. To make the side cover you can take a piece of galvanized steel and then

  • Cut 15 mm wide and 30 mm long galvanised strips to make the corner pieces. Then bend it at a right angle in the middle.
  • In the side open part of the cover drill holes with a diameter smaller than the thickness of screws. Fix the angles made earlier through the holes.
  • Cut the side covers from galvanized sheet metal to the contour.
  • Drill a hole near the edge for the branch pipe.
  • The branch pipe can be made by twisting a sheet metal into a pipe. The edges can be secured to each other with self-tapping screws or clamps.
  • One edge of the socket must be notched in several places. And bend these sectors.
  • Insert the pipe into the cut-out cover and fasten with self-tapping screws.
  • Also screw the obtained construction to the brackets with self-tapping screws.
  • Fasten the construction to the angle grinder.
  • Connects to the vacuum cleaner through the use of a corrugated hose. Use a clamp to secure the connection.

That’s it, angle grinder with hood for vacuum cleaner is ready to use.

Plastic canister model

There are always plastic jerry cans left in the garage after an oil change or antifreeze fill. Thick walls and mouldings in the corners give a good shape without deforming. The canister mouth is almost the same size as the vacuum cleaner hose.

Before you start cutting, determine the plunging depth of the cutting wheel. An installed dust trap will prevent the plunge. You can use the original cover as a base.

  • First use a marker to draw the lines.
  • Use a sharp construction knife to cut out the holes and cut off unnecessary parts. It is recommended to make the holes intended for landing on the angle grinder on both sides. This is just in case it becomes necessary to change the direction of rotation.
  • You can connect the hose to the neck with a clamp.
  • Attachment of the vacuum cleaner to the angle grinder is performed using a clamping ring with an adapter ring.
  • To cover the planting hole that is not used, you need to cut a circle of larger diameter and fasten with self-tapping screws.

Tile cutter attachment

To cut ceramic tiles, constant monitoring is necessary. And the extraction hood for angle grinders closes the view completely. To make the casing, you need a transparent material.

Use a 5 liter transparent water bottle as a template. A vacuum cleaner nozzle can be inserted into the neck. Use a stationery knife to cut out a hole for the seat.

Cut off the bottom of the bottle so that the disk is at the required height. The design is fixed to the angle grinder with a clamp or screws. The large volume of the bottle prevents dust from escaping, and the cover simultaneously serves as a dust collector.

The worker doing the work inside the room is not protected. And to protect himself from harmful factors, he can use a respirator and goggles, or install a dust collector or dust cover on the tool.

Angle grinder is considered a multifunctional tool. In addition to its many advantages, it has one significant disadvantage. during the cutting and grinding of material, it produces a large amount of dust. To free themselves from a long cleaning of the room after working with an angle grinder, masters use devices equipped with a vacuum cleaner. The main element of any such device is a protective cover. It can be easily picked up for any model of angle grinder. The main thing is to know how to properly connect the part to the extraction system.

Canister attachment

Homemade craftsmen have developed a more economical version of the modernization of the angle grinder with a hood for a vacuum cleaner. There is always a plastic canister from technical liquids in any workshop. Such a container perfectly holds its shape, quickly processed and has a factory outlet of the required size.

To make such a product, you will need the following tools and materials:

cover, angle, grinder, dust

Firstly, a fitting is carried out, the main criterion being to ensure that the cutting disc plunges down to the required depth. Use a clerks knife to cut the necessary through holes. Their dimensions are chosen so as to maintain the maximum rigidity of the product in the future. Both seating holes are cut out on both sides of the canister so that the direction of rotation of the cutting wheel can be reversed. Hose from a household vacuum cleaner is attached to the neck of the plastic container and secured with a clamp.

Then you need to attach the hood to the angle grinder with a strong clamp and a special adapter ring. The assembly of this part should be treated with the utmost care. The hole in the canister is closed with a cover that can be moved to the opposite side when changing the direction of rotation of the cutting wheel.

Such homemade dust collectors cost almost nothing, but are very useful. Construction angle grinder with dust protection allows you to do any kind of work in the rooms with the least amount of fine dust emission. To make a floor grinder, the shape of the nozzle should be changed a little, but it does not require a lot of time and effort.

Milling machine

In a milling machine, the main movement is performed by the cutter, which is used to process shaped and flat surfaces on workpieces made of different materials. The machine using an angle grinder can be made in these variants:

  • with movable angle grinder. In this case, the tool is securely mounted in the vertical plane to a special frame that allows you to move the angle grinder relative to the milled workpiece, which is fixed stationary;
  • With rigidly mounted angle grinder. In this design, the workpiece is moved in the desired direction, and the angle grinder is stationary.

In both cases, you need to think through the design, procure everything necessary for its assembly, as well as buy a collet-type cutter holder or make it yourself from a hexagonal. The figure shows a simple, quick-to-make construction of a router out of an angle grinder.

What else can be made?

The design of the angle grinder allows you to modify it with your own hands into many other tools.

Grain Grinder

The grain grinder is made from a round drum (from a broken or old crusher) with a peorized removable bottom, a plastic nozzle (from a regular canister with a cut off bottom) and the angle grinder. the leading element of the design. The shaft of the angle grinder is placed in the drum through a hole in the center of its upper part. In this position, its body is attached to the drum (the method of attachment is individual). From inside the drum, a screw-shaped knife is attached to the gearbox shaft. It can be made of a circular saw’s cutting wheel for wood. The knife is secured with a fastening nut.

The plastic hopper for loading grain is also installed in the upper part of the drum body. Through it, the grain is fed to the rotating blade. The latter is chopped up and discharged through the bottom opening. The size of the bottom opening influences the particle size. The photo below shows a model of a homemade grain grinder and the drawings for making it.

Twigs shredder

Shredder of branches and grass. a garden device that allows you to turn small branches and thick-stemmed weeds into a fine fractional form, used in various agricultural purposes. Making such a tool, it is worth using only a large angle grinder, working at high RPM. To prevent overloading and breakage angle grinder is used additional gear system, which multiplies the effect of chopping. The device is mounted on a strong metal base that can withstand heavy vibration and sliding loads. Such a device is shown in the photo below.

Electric chainsaw

Electric angle grinder saw is made with a chain saw guide bar of appropriate size. Since it is not possible to use an automatic rotation stop mechanism in a self-made construction, special attention is paid to the design of the protective cover. According to a similar principle, a saber saw can be designed with their own hands on the basis of an angle grinder. Chain saw is shown in the photo below.

Wood lathe

Wood lathe from an angle grinder is one of the most complex ways of modifying the latter. A large number of materials and various components are used to make it. An example of a construction is shown in the photo below.

Lopper

This is a tool that uses a benzoin grass trimmer in its construction, and more specifically, a gimbal. The principle of its operation is the same. only the driving unit and the cutting part itself are changed.

A chain saw bar mount is installed instead of a blade for grass cutting.

Accessories for angle grinder for mitre cuts

The angle grinder’s cutting attachment must include:

  • A second circular saw blade can be installed.
  • A nozzle for connecting a vacuum cleaner.
  • Protective cover to protect the operator from debris during operation.
  • Seat for mounting the vacuum cleaner cyclone.

The basic prerequisites for the performance of this attachment are. angle grinder must have a sufficiently powerful drive (not less than 1500 watts), and the length of the shaft, on which the main saw blade is mounted, must be long enough for mounting an additional blade, which will form the second wall of the intrenchment.

The diameter of the saw blade is also important, since it influences the working safety and the depth of the kerf to be cut.

Also important is the type of bearings on which the shaft rotates: the presence of a second disc increases the unevenness of the load, so the usual ball bearings, the allowable axial force on which is small, very quickly will fail, with the corresponding seizure of the shaft and failure of equipment. Needle roller or needle roller bearings are necessary.

Finally, during the rotation of the shaft movement of the saw blade should be performed to the working, and not from him (in the latter case, the total torque will push the angle grinder from the received with its help grommet).

The purchased angle grinder attachment is prepared for work as follows. Remove the protective cover from the gearbox. An additional bushing is mounted on the main shaft, which securely tightens the shaft with a clamping ring.

On the shaft the first diamond blade of the desired diameter is installed. from 150 to 230 mm, larger sizes will lead to an increase in the cantilever load on the bushing. It is not recommended to replace the diamond disc with another disc, especially if grooves are to be obtained in concrete. On the sleeve is dressed support washer (usually included in the kit for professional attachments include several such parts of different thickness, which determines the width of the reamer).

A vacuum cleaner nozzle is attached to the dust extraction cone with a simple adhesive tape. The gearbox of the angle grinder is attached to the extended control handle. It should be noted that any grommet cutter head on an angle grinder industrial production has a landing place for a removable handle, which is unified with the regular handle from the same manufacturer of the main tool. This is a limitation of the design in question.

After that, check the alignment of the two disks, fasten the housing to the lever support, align its course, and check the reliability of fixing all elements of the nozzle at idle, and then. and on the operating stroke.

Where to buy

Canister

If there are no welding skills or the wife flatly refuses to give permission to damage the pot, then there is a third option, how to make a protective cover with a dust outlet, which also connects wonderfully with the tube of a vacuum cleaner. What you will need for this?

Find in your garage, storeroom, or a neighbor canister. Of it a construction or ordinary knife hands need to cut design holes, in accordance with the shaft of the angle grinder and the location of the disk on it. It would be good to remember about the safety measures. Why? Banal. to preserve the integrity of your hands. over, it is important to choose the right knife. It must have a quality handle and should sit well in the hand without slipping out.

After it is necessary to fix the tube of the vacuum cleaner with the neck of the canister, so that it becomes like a nozzle. How? Cut the neck lengthwise and put on a clamp in order to tighten the tube of the vacuum cleaner with it. It is important to remember that in order to achieve a good suction of the vacuum cleaner, it is necessary to make sure that all parts of the hood fit tightly against each other.
