A casing for a grinder under a vacuum cleaner: selection and use

The angle grinder is considered a multifunctional tool. In addition to many advantages, it has one significant disadvantage - it generates a large amount of dust during cutting and grinding of the material. To free themselves from prolonged cleaning of the room after working with a grinder, craftsmen use devices equipped with a vacuum cleaner. The main element of any of these devices is the protective cover. It can be easily matched to any angle grinder model. The main thing is to be able to correctly attach the part to the exhaust system.

The casing for the angle grinder for a vacuum cleaner is a special attachment that allows the craftsman to be protected from the effects of dust, which, when working with a grinding tool, flies out from under the disk. Many hardware stores offer respirators for protective purposes, but these devices are ineffective. After a few hours of work, they begin to clog up, which means that they cannot cope with their functions. In addition, respirators are not designed to remove dust from the work area. Therefore, if repairs are carried out in a residential area, which has decorative trim and furniture, it is necessary to use a grinder with a dust extraction.

In most designs of grinders, a dust collector is provided. Thanks to him, dust is immediately collected from under the working surface of the device, without polluting the room. Such models are characterized by high suction power. They protect not only from dust, but also from debris. Additionally, a protective casing made of durable material is installed on the dust removal mechanism. It is able to withstand intense mechanical stress and, during surface treatment, collect various fractions, including fine dust particles, and pieces of metal or concrete.

The protective cover for the vacuum cleaner has two main functions.

• Dust protection. It prevents the spontaneous spread of debris in the work area. The dust protection element also traps small and large pieces of debris that are formed during surface treatment. In addition, this device also protects the tool itself from getting into the outer part of the body of various particles, which adversely affect the functioning of the rotating parts and can further damage them.
• Adjustment. The casing is not only responsible for dust removal, but also allows you to adjust the operation of the wheel.

Since cleaning is carried out with a vacuum cleaner connected to the nozzle, when installing the cover, make sure that the diameter of the dust extraction tube and the hole of the nozzle correspond to each other. The nozzle in the form of a flexible hose should fit exactly into the hole and slide over the casing without any backlash.

It is recommended to use a cover for a vacuum cleaner in the following cases:

• For grinding concrete and chipping walls, floors. This type of surface treatment produces a lot of dust. In addition, most of the work is done at a height, and debris falling from above can settle throughout the room. To increase dust protection, it is necessary to choose an aerodynamic or sanding casing that is suitable for powerful models of grinders and withstands well loads.
• When cutting tiles. Such work is always accompanied by a large amount of dust, which not only pollutes the room, but is also harmful to human health. For this process, experts recommend choosing a cut-off or universal casing.
• For scraping wooden floors. This process is quite time consuming. It provides for the treatment of surfaces of large areas, after which a lot of debris and dust are generated. Thanks to the protective cover, scraping is quick and efficient, since the master does not need to be distracted by cleaning the working area. It is installed on the angle grinder using special mounts.

The cover for the vacuum cleaner can be sold as a complete set with the tool, or separately. At the same time, many craftsmen make a protective device with their own hands in order to secure the working process. A homemade casing does not differ in functionality from the factory one, but it may be slightly inferior in performance. Self-made casings are able to protect the craftsman from injury, preventing particles of the processed material from flying away. But if the financial possibilities allow, then it is better to purchase finished products, since they are of high quality and allow you to expand the capabilities of the device.

Protective attachments play a huge role when working with angle grinders, and special attention should be paid to the choice of a casing for a vacuum cleaner. Since not every fixture can be suitable for a grinder and well protect the room from dust, it is important to consider some basic points before purchasing.

• For work with concrete surfaces, stone and brick, you need to choose casings with increased protection. Their body must be made of durable material. If desired, the protective equipment can be made and connected to the vacuum cleaner yourself, but this will require additional time and experience.
• The nozzle must correspond to the dimensions of the branch pipe and the modification of the angle grinder. This allows the tool to process the material without generating dust.
• The choice of the casing manufacturer is also considered important. Today the market is represented by products of domestic and foreign brands, but not all of them are characterized by positive reviews.

Protective covers for a vacuum cleaner for angle grinders are available in a huge range. Moreover, each of their types can differ not only in design, but also in functionality. Several models of attachments are very popular with masters.

• Bosch 2605510224. This casing is suitable for grinders of various brands with discs 115 and 125 mm. It is equipped with a special ring brush that allows you to work with a fiber attachment and a grinding wheel. The size of the nozzle is 200 × 190 × 80 mm, its weight is 0.3 kg. The cost is low.

• STOMER 98299441. This device is made in the shape of a semicircle. It is installed on angle grinders with 230 mm discs. The main advantage of the nozzle is the presence of a guide, which is responsible for adjusting the shaking depth. The size of the casing is 320 × 160 × 240 mm, the weight is 2.71 kg. It can also be purchased at an affordable price.
• Mechnik Air Duster. This variant is suitable for tools with 125 and 230 mm diamond discs. It is distinguished by its low price and the ability to connect to medium-power vacuum cleaners (up to 1.6 kW). The casing is lightweight and easy to install.

• Blastrak. This is a professional vacuum cleaner cover that can be attached to grinding tools with 125 and 180 mm discs.The nozzle is characterized by variable elasticity, it is more rigid at the points of attachment with angle grinders and soft at the edges in contact with the floor.
• Metabo GED125. This casing deserves special attention. It is recommended to purchase it for processing concrete and stone. The nozzle is completed with a special branch pipe that allows you to attach it to the vacuum cleaner.

To improve the efficiency of the protective cover, it must be correctly positioned and secured. The installation process is simple, even a novice wizard can handle it. Connecting the nozzle is as follows:

• first, you should close the standard grinder casing with an aerodynamic one, for this it is resting on the thrust bearing;
• then the casing is clamped onto the studs, it is fixed with screws, ensuring symmetry to the disk;
• the vacuum cleaner hose is connected to the exhaust pipe, it should freely pass into the hole in the casing;
• the installation process is completed with a control check of the fasteners, since work can only be started when the casing is securely fixed.
