Ways to make a hood for angle grinder for a vacuum cleaner with their 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 wood, then in the course of the work there is a large amount of shavings. To process concrete and wood angled grinder performed with minimal clogging, you need to make a cover for the angle grinder under the vacuum cleaner. You can buy such an attachment for a power cutting tool, but you can avoid the expense by making the attachment yourself.

Before you start working with concrete and wood, you need a good idea of what you are going to end up with. When cutting with an angle grinder is the formation of dust, 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 glasses. 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.

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

  • For paving in concrete, brick, cinder block, slate, and other similar materials. If shaping is performed at the construction stage, then the dust settling in the room is not as dangerous as in the case of renovation. When you cut tough materials, you crush them, which creates dust that settles all over the room
  • Cutting tiles and ceramic tile. the processing of these materials also generates dust, which is especially dangerous to 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
  • Woodworking. when sawing wood, not only dust is generated, but also sawdust, which can be easily and quickly eliminated with the hood mounted on the angle grinder

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

This is interesting!If there is no 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 needed, masters and experts do not even doubt it, as enough once to try to make cutting concrete, to be convinced of the need to purchase or manufacture a dust collector. What is better, to buy or make your own hands a hood for collecting dust 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

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

  • Grooving in the walls. The work is done on plaster and the cement and sand are of 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.
  • Sanding of wooden constructions. Before painting or varnishing, wooden products are subject to mandatory removal of pulp fibers, which are formed in the process of sawing. The pulp is thin, light and hangs in the air for a long time.
  • Removal of old paint coatings. Old paint must be removed before fresh paint is applied. A flap wheel is used. The paint it removes is very fine.
  • Cutting of floor and decorative ceramic tiles. Sintered ceramic is fine-grained and penetrates everywhere.
  • Sanding parquet or hardwood floors. Floors are leveled by removing the top layer. Roughness varies in height, and therefore, besides chips, a lot of wood dust is generated.

When the repair is finished, the dust has to be removed from every possible crevice and cavity. To protect neighboring rooms from construction dust, protective screens of polyethylene film or light fabric are installed in doorways. Special appliances are also used, which you can make yourself.

Purpose of the angled grinder dust bag

Using an angle grinder (angle grinder) for repair work on concrete in the home creates a lot of dust.

If you need to level a wall, sand it for painting or other types of finishing coatings, all the irregularities or bumps become tiny particles of concrete suspended in the air.

Despite the personal protection used, they penetrate the mouth, eyes, respiratory organs.

In addition, dust settles on all furniture, walls, ceilings and other surfaces, requiring laborious and time-consuming cleaning. Dust from brick walls gets into surfaces, irreversibly damaging their appearance.

There are several designs of hoods with an outlet for the vacuum cleaner hose, which significantly improve the process. They are purchased in the store and installed on an angle grinder, connected with a vacuum cleaner. Working with such devices practically completely eliminates the dust dispersion and greatly reduces the contamination of the room and internal air. Externally, they look like the usual protection, but with a closed housing and an outlet for connecting a hose to the vacuum cleaner.

Fabrication of the appliance

With a dust pan

When you can find an old aluminum pan, you can make a dust collector without using a welding machine. The main part of the casing is cut out and fit well to the angle grinder. When carrying out this work, the maximum penetration depth of the cutting wheel must be calculated accurately in advance, because the cross-cutting height from below depends directly on this.

From the other part of the aluminum pan, the seat is cut out for attachment to the angle grinder. The diameter of the hole should be measured directly on the power tool. The size of the vacuum cleaner must be as accurate as possible, so that the cover cannot come off from the strong vibration of the work.

Similarly, it is necessary to make a spigot for the vacuum cleaner. The protruding edges of the hood as carefully as possible along a single line to bend inward to secure the side wall, which can be made from any kind of material. For example, the wall can easily be made from thin metal sheeting. If there is a desire, it is worth to give the device more aesthetic appearance, treat the joints and paint enamel.

From a plastic canister

Next we will consider another economical option of dust extraction. Any person in the closet can find an empty plastic container from the various technical liquids. This container holds its shape very well and is quite easy to handle. And also such a container has a convenient branch pipe of the required size.

First, a fitting is made, the main purpose of which is to ensure that the necessary depth of the cutting disc is plunged. Use a construction knife to cut the necessary through holes. Their diameters should be chosen so that the homemade structure retains its rigidity. On both sides it is worth making special seating. This makes it possible to change the direction of rotation of the cutting disc.

Next, the hose of the vacuum cleaner needs to be connected to the neck of the jerrycan and fastened well with a metal clamp. The cover is mounted securely to the angle grinder with an adapter ring and metal clamping. The assembly of the assembly is very carefully done. The second hole must be sealed with a cap. When changing the direction of rotation of the cutting disc, the cover is transferred to the other side of the can.

Such devices, made by their own hands, have a low cost, but the benefit from them is 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 form of nozzle on the angle grinder. However, it is not much different from the products described above. It can be made in the same ways, using almost any material.

Variants of covers for angle grinder

The hoods on the angle grinder for the vacuum cleaner can be made by yourself, so there is no need to spend money on the factory nozzle. In addition, there are more than enough options for making a homemade hood. Consider a couple of options for making nozzles for angle grinder, which will help to work indoors “without noise and dust. As for noise, the use of such nozzles also reduces the noise level, although insignificantly.

The first version of the hood involves the use of a pan. You can make a pan cover without much difficulty and even without using a welding machine. The only condition is the presence of an old aluminum pan. For making such a nozzle it is necessary to cut out the cover from the pot, adapting it to the size of the power tool.

Important to know! The use of material such as steel would not be relevant, since it would be necessary to use welding to make the casing.

Having determined the depth of penetration of the wheel, you should remove the excess part of the pan, which can also be done with an angle grinder. In the received part of a pan it is necessary to cut out a hole under a landing axis. You can measure the diameter of the axis directly on the angle grinder itself. Diameter must be as accurate as possible, otherwise the nozzle will slip during work.

In the back part of the resulting nozzle you should make a hole for the vacuum cleaner hose. In this hole, which is called the dust outlet, should enter the tube of a vacuum cleaner to suck out the dust. The presence of a dust collector or dust collector allows you to perform the main task, to eliminate dust in the room when working with the tool. The edges of the hood should be bent inward as a final step to hold the side panel in place.

The side wall for the protective hood of the angle grinder can be made of any material. It is best to use a thin sheet of galvanized steel, or straighten the rest of the pan. A suitable piece of metal should be cut out and screwed to the main product with self-tapping screws. The photo below shows a view of the hood obtained for the angle grinder with your own hands.

You can also make the cover from a plastic canister. This option is also economical and even easier to implement. To begin with, you need to find an empty plastic canister, which is necessarily available in the garage. Proceed with the measurements, as an important condition is to ensure the required depth of immersion of the circle.

Important to know! The size of the required canister depends on the angle grinder. A liter canister from oil or brake fluid will do for 115 mm disc grinders.

Work on cutting out the casing with a construction knife. Canister neck should be left, because it will play the role of a dust collector or to attach a hose from a vacuum cleaner to it. We recommend to cut a hole at the level of the axis of the angle grinder, the size of the nut fixing the working disk. This makes it easier to replace the worn disc.

After the product is ready, you can put it on the tool and try it out in action. You should get something like this in the photo above and below. Such a hood is not only easy to make, but also does not require any additional costs.

Depending on the material and manufacturer, factory nozzles will cost from 600, but is it worth buying such a device when you can make it yourself without much difficulty. Especially relevant are the above options in those cases where you want to perform single work in the room, but you want to reduce the occurrence of dust.

To homemade or purchased cover for angle grinder must be connected only a construction vacuum cleaner, it is designed to work in this mode. Household (domestic) variant of the vacuum cleaner is not recommended, as it can not cope with large amounts of dust. It very quickly will fill up(will be blocked) a dust that can lead to failure.

General recommendations on the use of the angle grinder

When working with a tool such as an angle grinder, safety precautions must be followed. Vacuum cleaner cover for angle grinder. it is not only an option, how not to make a mess in the house when working. The advantage of such a cover is to protect the person doing the work from various factors. Working without a hood is like playing Russian roulette: with or without luck.

During the work of the angle grinder are possible options for such negative consequences as the breakage of the wheel, which is not uncommon with abrasive discs, as well as the appearance of small fragments and pebbles that can get into the eyes. The harm of dust arising from the processing of concrete and ceramic products is that it can reach the lower compartments of the respiratory organs. Carry out works on cutting concrete or ceramics without a protective cover and a respirator is strictly forbidden. It is especially important to wear a respirator and safety glasses if work is performed without a protective hood.

An angle grinder is an indispensable aid in carrying out various jobs. With the advent of these tools, manual labor has become much easier, but the possibility of injury has increased. In order for the tool to continue to be the best helper in the household, design a homemade cover for it, protecting yourself from possible serious injury.

How to make a hood for angle grinder for a vacuum cleaner the best ways

The advantages of making the nozzle yourself are as follows:

  • No need to spend money to buy the device
  • Ability to make the device according to your requirements
  • No need to travel in search of a suitable device

There are many options for making a hood on an angle grinder for a vacuum cleaner, and when you make your own, it is not necessary to make such a tooling, which is already invented. It all depends on personal abilities, capabilities, as well as the available material from which you plan to make the nozzle. To facilitate the work of making covers, consider a few options on how to convert the angle grinder to a vacuum cleaner.

Safety precautions

If you decide to make a cutting machine from an angle grinder with your own hands, you must remember about safety. If the option will be stationary, it is important to consider the direction of the tool and the position of the hood, which should cover the area where the operator is located. If you have a machine, you may be faced with the need to fix to the angle grinder a saw blade for wood. No matter how strong the desire, to do it categorically not.

Wood is not a homogeneous material, which can be knots or nails. Angle grinder works at high speed of rotation, which exceeds the speed of a standard saw. It rather quickly puts a saw blade out of operation.

Comparing sanding and abrasive discs with saw blades, you can understand that the latter have sharp teeth. For the sake of a quick sawing it is not worth risking your health. After installing the equipment and a new disk work angle grinder should be checked for a minute, running the device at idle speed. The wheel should not hit any obstacles or the guard.

Stroborezmer from the angle grinder with their own hands

Stroba is a groove that must be cut into the wall for laying electrical wire or cable. The difficulty of this work is that the groove must be a constant width and depth. Then the wire will be laid evenly and mortar for laying will need less.

Stroborez in practice is rarely used, so buy it for the house will be expensive. But it can be made with an angle grinder. our favorite angle grinder.

The main task is to install two diamond discs on the shaft of the angle grinder with a distance of at least 1 cm:

  • Install the first disk and fix it with a nut;
  • Install the second disc and secure it with a nut;
  • measure the resulting distance between the discs;
  • install the guard on the angle grinder;
  • check the function.

But if for some reason it is not possible to install two discs on the shaft, you can cut a slot and the usual method of one installed disc. You just have to cut a second parallel line for the trimmer.

Work with the hole saw must be done indoors. This creates a huge amount of dust. Not even a respirator can protect against dust. To eliminate this negative phenomenon it is necessary to make a protective cover, which would cover both discs and have a top spigot to connect to a vacuum cleaner. There is a similar device on electric jigsaws for collecting small sawdust. Sometimes, lovers of rational use of the tool attach 2 or 4 rotating rollers to this cover. When moving on the surface of the wall, the stubber will move on rollers, not creating additional loads on the hands.

To make a tool for a wide groove you need to make special sleeves to attach the discs to the desired width. With this reamer you can make grooves for laying pipes.

But it is necessary to make a wider protective cover. On the cover chisel both for wires and pipes it is necessary to install a screw to adjust the immersion of the cutting tool in the wall. In this case the cover will consist of two parts connected by a hinge and a node to regulate immersion.

Dust extraction from a plastic canister do it yourself

The easiest and most economical option to make a cover for angle grinder for a vacuum cleaner. is to use a plastic canister as a base. To implement such a variant of the cover you need to take a canister of appropriate volume. Usually a one- or five-liter canister is enough, but it all depends on the size of the tool itself.

The principle of making a cover is quite simple, and to implement it, you must first prepare a drawing, according to which the dust extraction nozzle is made. When making it, such factors must be taken into account:

  • Consider nozzle size, which depends on the plunging depth of the cutting disc. The bigger the nozzle size, the shallower the depth of cut you get
  • Drill a hole of an appropriate diameter depending on the size of the sleeve to install the unit on the shaft of the power tool and secure it
  • Make hole on one side to fasten the unit to the shaft of the power tool. On the other hand, it is not necessary to make a hole at all, as dust can seep through it, which will reduce the effectiveness of the nozzle
  • The neck of the canister is used as a bracket for connecting the hose from the vacuum cleaner. To connect the neck of the canister with a hose from an industrial vacuum cleaner, you should use a coupler or clamp

To construct such a device you need a minimum of time, effort and expense. The result should be a device for dust extraction when cutting concrete, tile and wood.

Installation instructions

To increase the efficiency of the protective cover, it must be properly aligned and secured. The installation process is simple, even a novice craftsman can cope with it. The connection of the nozzle is as follows:

protective, cover, angle, grinder
  • At first it is necessary to close the standard cover of the angle grinder aerodynamic, for this purpose it is resting against the footrest;
  • then the hood is clamped to the studs, it is fixed with screws, ensuring symmetry to the disk;
  • Vacuum cleaner hose is connected to the exhaust pipe, it must pass freely into the opening of the hood;
  • The installation process is completed by checking the fasteners as you will not be able to start working until the cover is securely in place.

On how to make a cover for dust extraction for angle grinder with their own hands, see the following video.

Hey, guys! I’ve been coming in a lot.). But it happens to beginners. There are a lot of topics. I want to ask a lot, share a lot. In general, the theme is this. When I encountered sanding fiberglass, I realized that it is a crap, to put it mildly. I have an orbital machine with a vacuum cleaner, but not an angle grinder. And since I roughly first grind it, the picture looks something like this:

The cover on the angle grinder. Almost a budget solution to the problem of dust extraction when sanding walls

Today I’m going to continue the renovation theme. Since I started it, my arsenal has greatly increased tools and one of them I want to tell today and. If you ever started repair in the secondary, you know very well that one of the most difficult tasks will be to prepare the room for the actual repair. Anything that doesn’t hold up well, crumbles or doesn’t like it. it all needs to go away. And often, it takes a lot more effort than building a new. Here I was faced with the problem of scraping the walls for plaster and putty. My walls are reinforced concrete with a rich cultural layer from the 80s. there’s old plaster, traces of putty, wallpaper, whitewash, tile adhesive, etc. I found two solutions to this issue. either clean peoratorom, spatula and grind with a hand grinder, or clean angle grinder (in the world angle grinder). The first option quiet and long, and the second noisy and very dusty. Because I am lazy, I was not satisfied with the first option, and anyway the dirt remains from it, tried the second, but I was not long enough. the dust when cleaning the walls of paint over concrete plaster was so much that neither breathe, nor even see something I could not.

In general, then I decided to buy a more powerful vacuum cleaner, after watching videos on YouTube, where builders show master classes. Almost everywhere the vacuum cleaner was a permanent resident of the construction site. But buying a vacuum cleaner is half the battle. Vacuum cleaner to the tool still need to connect.

I was supposed to clean and sand with a small 125mm angle grinder. I have a 900-watt Skil with a small gearbox and theoretically its power is not enough, but I decided to try it. A cursory research of the issue showed that there are in nature special dust shrouds, in particular for Bosch (in idea my version, Skil is a daughter of Bosch and it seems the shrouds should be compatible), DeWALT, Milwaukee, and even for Interskol. The first options were very expensive. from 2700 for Bosch, and are out of stock for that kind of money. Interskol is listed at 1300, but is not available anywhere and it is unclear when it will be available. Of course, there are a lot of videos on the Internet about how to make a cover from a sewage flange and a matching cup, but I wanted a ready-made version.

On Ali it was found on the request Dust Shroud. But the price tag of 30-40 bucks made me scared away. And then, surprisingly, the same request on Banggoode found a cheaper cover. It’s what I ordered, plus I found a coupon somewhere for a discount, even points did not have to spend. Arrived guard for 20 days by mail in China, was packed in a box enclosed in a package. Basically it was ok, there was a small piece chipped from the detachable part, but nothing critical, it doesn’t affect the performance.

Let’s look at the hood itself.

The cover is universal for size 4-5″. That is, it is technically suitable for grinders under the wheel 115-125 mm. Versatility is achieved by attaching. In the case there are three radial grooves in which the hooks move. We tighten the worm clamp, the hooks are pulled to the place of attachment of the regular cover on the angle grinder. I forgot to measure the diameter of the dust outlet. it is about 20-25 mm, a little shallow, although the performance of 125 drive is not so great.

You can see the slots from below. Around the edges of the body is framed with a brush, it is needed to trap dust and ensure a tighter fit of the nozzle to the surface to be treated. I want to tell you right away, the brush is a little crooked and with a gap in one place. A little later in the photo will be seen better. You can also see the screw heads. They are needed to adjust the depth of the housing in relation to the tooling.

The more screws are tightened, the deeper the cup body sits and the working edge of the jig can be aligned with the brush, and the adjustment range is pretty good, it can be used for different types of jigs with different depth.

To be able to get the tooling into the corners, the part of the housing with the brush can be removed by sliding it down.

Let’s try on the angle grinder:

It did not fit perfectly. But there’s payback for versatility. I have the hooks in the gearbox and it is only in one position that the housing sits more or less flat. I tried to screw the cup under the sanding discs with velcro. You can see that the bristles are obviously defective in one place:

Then I connected the vacuum cleaner. Included with it was a step crossing, but it did not fit. the first step is small, and the second does not fit. I wrapped some cloth tape and the adapter of the first stage stood firmly. After installing a larger diamond cup it became clear that the shell is not centered and alas, it could not be aligned. the hooks rest against the gear housing. This is how the unit looks when ready to work:

The cover performed better than I expected. I was worried, that the dust would fly from under the cover, especially from the hooks grooves. But no, there is almost no dust, unless, of course, you chew on the wall at an angle. The vacuum cleaner properly removes dust from the work area, a little dust around arises because of the groove in the brush. Theoretically, the problem can be solved by winding around the perimeter masking tape, somewhere on YouTube saw this tip.

To summarize. The tool is definitely useful. Pros: 1. Works as advertised; 2. Versatile. allows you to work with several grinders and different depths of tooling; 3. There is a removable sector to work in the corners.

But there are also disadvantages: 1. The plastic is quite fragile. You can not drop it, you have to be careful; 2. The quality of craftsmanship brush seams. It makes part of the dust fly out; 3. The fastener is not the most convenient, the hooks rest on the gearbox. If the gearbox housing is big, it is possible that you won’t be able to mount the shroud properly.

In general, for home use on small volumes. will do. But not more. If you need it for more serious job, try to find the hood from Interskol, the price is not much more expensive, it should be of higher quality.

Casing on the angle grinder under the diamond cup 125mm for dust-free grinding of concrete.

Hello. Today I will tell you about a useful device that will get rid of dust when grinding building structures with an angle grinder (popularly angular grinder) with a diamond cup. During the construction of the house needed a tool that could smooth out small irregularities in the screed before laying the laminate flooring. Specialized grinders are expensive, and buying such a tool for one-time use did not seem to me advisable. Since I already had a DeWALT angle grinder 125mm and a construction vacuum cleaner, it was decided to buy a nozzle with a pipe for dust extraction. After surfing the Internet, I realized that buying the original nozzle on the angle grinder DeWALT in Moscow stores will not work, because at that time they were out of stock. And the price was scary. It was decided to search the expanses of the Internet for a universal attachment.

After a long search, found what I need in a Chinese store, where I often shop, and immediately ordered. I had some doubts about the quality of the material used to make the hood, but in practice it turned out that the plastic is very strong, and it is difficult to break it. Feels like polycarbonate, elastic enough not to burst from stone flying out from under the cup. Fasteners are adjustable, but in fact, to fix the diamond cup, which are sold at construction markets, you need to fully tighten the screws, pressing the cover on the tool. And it still wasn’t enough, because the sealing brush was sticking out beyond the working plane of the cup. Which would lead to rapid wear and tear. The solution was found by adding a washer under the cup. After this operation, everything was back in its place. To put the hose from the vacuum cleaner, I had to wrap some duct tape on the outlet pipe of the casing, to seal the connection. In order to get close to the corner with the tool, you need to remove the removable part of the cover. It is not easy to remove, I had to tap it lightly with a hammer. But there is no risk of spontaneous popping out when working with the tool. If the vacuum cleaner bag is not clogged and the draft is good, there is no dust at all. On the plus side: 1.No dust at all. 2. Inexpensive, relative to the original hood. 3. Sturdy housing. Cons: 1. Because of the construction of the housing, it is necessary to add a washer under the cup.

I am completely satisfied with the purchase. I think that its cost is worth it. If you have any questions, ask in the Комментарии и мнения владельцев. Thank you all for your kind attention!

Assembling varieties

The nozzles differ in diameter and shape of the pulley, respectively installation schemes will differ in some nuances.

  • The popular version with a fixed pulley and closed cup fits STIHL brushcutters. The clutch is removed before installing.
  • There is another option. mounting the pulley without the cup, in which case the clutch is not removed, so installation is quite simple. Several versions are available on the market, depending on the sprocket pitch. This attachment is more suitable for Chinese chain saws, Husqvarna, Partner.
  • Special pulleys for professional petrol saws, in which it is possible to replace the drive sprocket.

Safety instructions

As with any electric tool, the necessary electrical safety instructions must be observed. Not allowed to work in rooms with high humidity. When installing the machine outdoors, it is desirable to build over the workplace at least a temporary shelter to protect against precipitation.

Like any cutting tool, the angle grinder, even if it is fixed in the machine, requires strict compliance with safety precautions. Working without protective guards around the circular saw blade is absolutely inadmissible. Safety glasses or face shield must always be worn.

Many people neglect gloves. and for good reason. Sparks may only seem small and harmless when they are flying out from under the saw stone. Crumbs of abrasive and abrasive material fly like bullets and can penetrate deep into the skin.
