What are the attachments for the angle grinder

Angle Grinder Discs (Angle Grinder)

Angle grinder (angle grinder, angle grinder) is a tool with which it is possible to perform several types of work. In each case, the use of additional devices is required. special discs and nozzles. Which circle to choose in a particular case?

The sizes of discs designed for an angle grinder may vary. Each of them has certain diameters. internal and external. The inner one is linked to the fit size of the angle grinder. For household grinders, it is the same. 22.2 mm. The depth of cut or the area of ​​the ground surface depends on the outer diameter of the wheel. A larger blade gives a deeper cut. Outer disc diameters for angle grinder: 115, 125, 150, 180, 230. Wheels have different thicknesses. When choosing, you need to give preference to those that are thicker. Thin disc will wear out faster.

Classification by type of work

By the type of work performed, circles to an angle grinder are:

• Cut-off. They are designed for making cuts, rough cuts, etc. The cutting disc has a cutting edge that is a solid circle or is divided into segments.
• Sawing. The cutting edge has teeth. An angle grinder is used to trim many types of wood products and wood substitutes. To get the job done, you need a saw blade. This type of circles is designed for smooth, clean cuts of solid boards, plywood, parquet, drywall. It is also suitable for laminate, fiberboard, chipboard (including laminated), as well as the selection of grooves in gas silicate.
• Rough (grinding wheels). Such nozzles remove the old layer of paint, varnish, primer from the surface to be treated, and polish.
• Stripping. This is a kind of peeling. These include disc metal brushes. They can remove rust and other stubborn dirt.
• Petal circles. They are also referred to as stripping. The flap disc is used for processing metal, wood, plastic products, cleaning welded seams and burrs, removing rust, etc. A flap disc for an angle grinder consists of plates overlapped around the circumference, according to the principle of flower petals. Varieties: end, batch, with a mandrel. The flap disc for an angle grinder is designed for processing at an angle or normal flat. There are two subspecies of it. straight and conical. A straight flap disc is needed when grinding over a large area. Flap cone disc is suitable for finishing seams, joints, etc. The flap (folded) batch disc is also suitable for work on a large area. Grinding wheels with a mandrel for an angle grinder are used when working with cavities. They help to achieve the highest machining accuracy.
• For cutting seams. They are used when making joints in concrete, asphalt, etc. With such attachments, the grinder is also suitable for this work.
• Polishing. Such wheels are used for the final polishing of surfaces. These include replaceable polishing felt and felt attachments for an angle grinder with Velcro, as well as an emery wheel.

Extra options

With angle grinders, the grain size plays an important role. The higher its value, the finer the size of the abrasive particles, which means the finer the grinding:

• 40–80. preliminary processing;
• 100–120. alignment;
• 180-240. final sanding.

Grit sizes for flexible diamond polishing wheels: 50, 100, 200, 400, 600, 800, 1000, 1500, 2000 and 3000 (finest grit). Grit is indicated by the marking on the back.

There are four types of diamond cutting discs:

• Solid (“Crown”). They are designed for wet cuts only. The cutting edge is continuous. This type of circles provides faster work performance, makes even cuts without chips.
• Segmental. Segmented discs have evenly spaced slots on the cutting edge directed towards the center. They divide the disk into equal parts. segments. Segment wheels are used when performing dry cuts.
• Combined (“Turbo”). The disc edge has a serrated shape, consisting of oblique grooves. This type of disc is versatile, suitable for dry and wet cuts.
• Turbo segment. Their edge is also jagged, but it is divided into segments, like a segmented disc. Suitable for dry cutting. Special shape improves productivity.

Many types of materials (concrete, ceramics, etc.) generate a lot of dust during cutting. It is advisable to avoid harmful consequences for the person performing the work, as well as the deposition of dust on the surrounding objects. Therefore, the technique of “wet” cutting is used. During work, make sure that the cutting edge is moistened with water, then there is less dust.

On sale you can find wheels for an angle grinder with a flange. The flange fixes the circle reliably and quickly, increases rigidity, reduces vibration, increases machining accuracy, expands the capabilities of the tool, allows you to process “dead zones”, flat corners.

Types of discs

What kind of discs are there for an angle grinder? Wheels for an angle grinder are classified according to the following parameters:

• type of work;
• the material from which the circle is made;
• the form;
• dimensions.

There are special circles. for wood, metal, concrete, artificial and natural stone, etc. The marking indicates which material the nozzle is suitable for. Each type can be suitable for several types of processed surfaces. For example, a stone disc for an angle grinder cuts concrete, brick, ceramics, paving slabs, etc. But it is impossible to cut or grind metal in a circle on wood or a stainless steel nozzle on rough steel. The angle grinder can process, among other things, asphalt, plastic, glass, fiberglass. If necessary, you can find special discs for an angle grinder (angle grinder) for porcelain stoneware, granite, reinforced concrete, marble, ceramics, tiles, bricks, plastic. If you want to save money, it is preferable to look for a universal circle that processes several types of materials at once.

Material classification

• Diamond. They are made of diamond-coated steel. This type of attachments cuts and grinds any metal, concrete, artificial and natural stone (including granite and marble), ceramics, glass. The diamond saw blade for the angle grinder provides the finest cut. You need to cut with small cuts. A new type of diamond attachments. polishing wheels on a flexible base (“turtles”). Their surface has a corrugated structure in the form of a turtle shell (hence the name). Flexible diamond discs are attached to the base. a hard rubber attachment with Velcro.
• Carbide. Circles of this type are also made of metal. They have high-carbon molybdenum steels with additions of chromium and nickel at the edges. They are used mainly for cutting metals, less often for wood. The angle grinder is suitable for many metals. There are carbide discs specially designed for thin, high carbon, stainless steel, aluminum.
• Abrasive. The base is thick waterproof latex paper with reinforcing mesh or fiber. A layer of abrasive material is applied to it. particles of aluminum oxide, silicon carbide, tungsten carbide or corundum. The bond for the abrasive is resin or polymer. The grinding fiber disc for the angle grinder is used in conjunction with a backing pad made of plastic or rubber. It serves as a stop and cools the abrasive. Abrasive wheels are used as cutting, cleaning or roughing wheels. Fiber discs are suitable for working on wood and concrete, processing non-ferrous and ferrous metals. The abrasive is zirconate or aluminum oxide, ceramic grain. Fiber disc is ideal for rough removal of old paint from walls, facades and other surfaces.
• Metal wire stripping. Disc brushes made of this material are used to remove rust and other types of stubborn plaque.

Discs for an angle grinder can conditionally include backing pads. They are also called backing discs or poppet discs. Plates are made of plastic or rubber. They are used in combination with some grinding, polishing, grinding abrasive attachments, emery wheels. The need to use a platter should be clarified when buying a particular wheel for an angle grinder.

Metal brushes for angle grinder for cleaning rust and processing wood

Many people believe that only steel products can be cleaned with the brush attachments that are used with an angle grinder. However, such tools are also used when it is necessary to process wooden parts. For wood, use brass wire nozzles.

Brushes have several advantages over abrasive discs. They are distinguished by a long service life and a lower cost. They are used when it is necessary to remove rust or old paint from the workpiece. Separately, it should be said that brushes are indispensable tools when processing hard-to-reach places.

Brass attachments for wood angle grinders allow you to remove paintwork as efficiently as possible. Brushes are used not only for cleaning surfaces. This tool is also used when it is necessary to artificially age wood. This process is called brushing.

Brushing is used to create unique designer interior items. Using an angle grinder, you can process small items. On an industrial scale, such a tool is not used. Brushing attachment for angle grinder allows you to highlight wood features such as rings and unevenness.

Metal brushes are able to quickly and efficiently remove old paint from steel pipes, remove rust and deposits. When choosing such nozzles, it is imperative to pay attention to their rigidity, since the operational efficiency of the brushes depends on this indicator.

Angle Grinder Attachments for Rough Cutting of Various Materials

For rough grinding of various surfaces, special discs are used, which have their own characteristics. Rough processing of wood is aimed at removing knots, as well as a layer of bark. Using these attachments for metal workpieces removes paint and rust.

Today, there are several types of grinding attachments for angle grinders. For example, roughing discs are very popular. Among them there are products that are used for processing stone and concrete (diamond) and abrasive wheels used for metal parts.

Roughs are often used to remove old paint layers. In some cases, they are used to remove varnish. Another common version of the attachment for an angle grinder is a brush. The design features of these elements are reflected in their effectiveness. A disc that has a metal wire is able to quickly remove paint from a metal surface.

Note! In the building materials market, you can find end wheels for an angle grinder. Similar products are used when it is necessary to align the cutting line of the board. Aligning the ends with an oblique cut is done quite often, so this tool can be called indispensable.

Separately, it should be said about the nozzles for car polishing. For rough processing of paintwork (LCP) machines use special woolen discs. The material in such a circle can be located freely or twist into dense threads.

Also, for rough processing of cars, abrasive discs are used, which are distinguished by high functionality and a longer service life.

Today you can find other attachments for an angle grinder for polishing a car. For example, felt and felt discs are very popular. For the finishing of the car paintwork, vulcanite nozzles are used, the main material of which is rubber.

Angle grinder attachments: coarse and gentle sanding

Grinding is one of the most popular processes for which an angle grinder is used. With the help of such a tool and a set of nozzles, you can carry out rough and gentle processing of metal, stone and wood surfaces. As a rule, sanding precedes the polishing of the workpieces. The attachments used in this case may consist of sandpaper or felt material.

The flap disc for the angle grinder is widely used. This tool consists of a circle (base), along the edges of which sandpaper petals are fixed. They can have different grain sizes. This indicator is selected depending on the nature of the work.

The use of a flap wheel allows for rough machining of workpieces from different materials. It can also be used for finishing grinding. Fine-grained petals are used for finishing.

Today you can find another type of grinding discs for an angle grinder. Some abrasive products are fixed to the backing with a special velcro. To use such a circle, you need to screw it onto the tool spindle.
