TOP-15 rating for angular grinder of 2022: an overview of the best grinding, cutting and diamond models

Without such an instrument as a corner grinder, no more or less serious repair can not be completed. But she needs an assistant. Nozzle. And choose such nozzles correctly. How. Now we will tell.

Corner grinder (technical name angular grinding machine, corner grinder) is used during home repairs, and at construction sites.

The list of technological manipulations that it helps to carry out is large, but let’s talk a little about something else, namely: how to choose the right nozzles and disks for corner grinder.

Top 10 awesome and useful angle grinder discs

They are selected for its intended purpose (depending on the material and the purpose of the work) and in size.

which, disks, suitable, corner

The assortment in stores of power tools is great, but not everyone can approach this issue professionally. Just on such doubt and not understanding our article and is designed.

Types of disks for corner grinders

Circles for corner grinders are interchangeable elements. Performing work with different materials, it is necessary to understand their types. This will help to perform a qualitatively necessary operation. Circles are classified according to these parameters:

  • By purpose;
  • Type of work performed;
  • Constructive execution;
  • Type of cutting;
  • Manufacturing material;
  • Sizes.

which, disks, suitable, corner

By purpose, there are nozzles to perform work on metal, wood, stone, concrete, marble, etc. D. Manufacturers indicate the purpose in the marking, which is applied directly to the product itself. Many varieties are a universal tool, suitable for processing several types of materials.

By the type of work performed, which is indicated in the name, manufacturers produce the following nozzles to the angular grinder:

  • Feed vehicles (metal brushes, circuits of petal end, with a mandrel, bags);
  • Pendric (grinding circles, spit.Shaped balls, sprouting diamond);
  • Saw. The presence of teeth on the cutting edge is a feature of the design of the product. This allows you to get special purity of cut on wooden, drywall, gas silicate, plywood and other similar materials;
  • Cut.Off. Cuts and diamond discs are produced with a continuous cutting edge and divided into segments;
  • Grinding (disks with varying degrees of grain and hardness);
  • Polishing (nozzles of felt, felt, with special Velcro and grinding);
  • For cutting seams in asphalt, concrete, etc. D.;
  • Milling (for cutting grooves, bowls, processing of edges, etc. D.);
  • Sharp. A characteristic feature is the ability to perform surgery with a side surface.

The disk is a product of a certain diameter and thickness, which has a landing hole for attaching to an angular grinder with a cutting edge of a continuous, segment or curly configuration. The choice of a particular type depends on the operation and the material on which it will be carried out. Cutting using such nozzles can be performed with a dry, wet and combined way. This feature is indicated in the marking.

Disks on the material of manufacture are abrasive, carbide, diamond and brush. The basis of the first type of circles is special latex paper or fiber, on which an abrasive layer with a binder is applied. The nozzle made of fiber is supplied with a rubber or plastic support plate. Cool disc. A product made of alloy steel. Such consumables can be used for cutting aluminum, stainless, high.Carbon steel and other materials, which is indicated in the marking.

Diamond discs. Universal consumable. Is a steel product on the surface of which diamond spraying is applied. This allows you to get the thinnest cut in any material. Popular products, popularly called turtles. A type of nozzle made on a flexible basis, has a corrugated structure and is attached with Velcro. In addition, diamond discs are produced with a solid edge for cutting a wet method, segment and turbose.Healing for cutting a dry way and combined.

Types of circles

Circles (discs) of the Bulgarians are distinguished in the following indicators:

Technological features

The necessary processing technology is provided by the following consumables.

  • – Refined circles. Mostly used for metal processing, less often for other types of materials.
  • – Grinding circles. Different design executions allow you to perform both peeling or cleaning, and bringing the surface roughness to the desired condition.
  • – polishing discs and nozzles. Bring the surface to shine using felt or other fabric properties.

According to the material

The mode of operation is influenced by the material component from which the tool is produced.

  • – Abrasive disk. The basis that served as a tool is an abrasive material itself, a binder, for example, bakelitis and all kinds of fillers. Used mainly for metal processing.
  • – diamond circle (with diamond spraying). With its help, you can process materials of any strength (various rocks of stone, ceramics, quartz glass and many other similar ones consisting of solid fractions).


The main criterion for the classification here is the diameter of the disk. The depth of the cut depends on its size (it is approximately a quarter of the diameter). The functionality of the corner grinder is determined by the size of the instrument: a small diameter makes it possible to process the light angular grinder in hard.To.Reach places, and the angular grinder with a large size with greater productivity will be difficult and unsafe to keep “by weight”.

Varieties of disks for corner grind

Not only dimensions distinguish elements from each other, but also their functional purpose.

Cut off nozzles

Most often, an angular grinder is used to cut something. Naturally, the type of circle is determined by the material with which the work is:

    Metal nozzles. For their manufacture, Corundum crystalline clay and synthetic corundure is also called, which is also called an electric rousse. They are painted blue.

Attention! If there is an insurmountable need to use exactly the angular grinder for sawing wood, then this must be done in compliance with all safety measures. The tool should have both a protective casing and an additional handle. The user works only in personal protective equipment: with glasses and gloves. Such circles should only be used for wood. But it is better to take the discs that are equipped with a chain, like that used in chainsaws. If the circle is jammed, the chain remains motionless, the nozzle itself makes idle rotation.

Disks for peeling and stripping

Before covering one or another surface with fresh paint, an old layer must be removed. Preliminary stripping requires rust. For these cases, pendants are used. On sale there are brushes of two varieties. They can be disco or bowl.Shaped. But in both cases there is a metal wire.

The wire of the retinue itself in separate cords or simply fluffed. Its diameter is different. The quality of processing depends on the thickness. If only a rough, but fast peep is required, then brushes with thick wire are used.

Polishing and polishing circles

The initial purpose of the corner grinder is to help a person with grinding and polishing. They can very quickly (albeit roughly) process any surface, but are also used for finish manipulations. For this, a lot of all kinds of grinding and polishing discs have been developed, among which:

  • Cord brushes for black processing or for stripping.
  • Toris abrasive nozzles. For bockeys of workpieces.
  • Petals. This is a special type of circles that are made of an abrasive canvas of varying degrees of granularity. The quality of the result directly depends on the size of the grain.
  • Circles from felt. Use when it is necessary to polish the surface to a mirror state, while using fluids for polishing or special pastes are used.
  • Fiber nozzles. For metal surfaces.
  • Chain and circles-chubs. For working with wood. To do this, it is necessary to put an additional handle on the corner grinder.

Elevator paper can be fixed with Velcro on the nozzle. In this case, it is attached to the spindle of the corner grinder.

which, disks, suitable, corner

There are many different circles from felt in stores, which are used for polishing work.


Among a wide variety of disks for power tools, you can find options for milling. There are only two varieties. Classic and mills. The side part is intended for work and outwardly it looks like a rashpil. They are roughly treated with wood. Cutters not only differ in their form. They have the teeth differently located. This type of discs work:

  • Making grooves;
  • Choosing a wood of wood from recesses and bowls;
  • Cleaning the bromic and end parts of objects;
  • Smiling details of small size.


For sharpening, ordinary discs are used: they are the same for both the Bulgarians and for machines. The main thing that distinguishes them from the detachment is the thickness, as well as the ability to use the side part for work.

The section of such circles is at least five millimeters. They are used not only when it is required to sharpen the cutting edge of the tool, but also to clean the surfaces from signs of welding, and if you need to roughly process the part.

Corner grinder disks what are

What disks are for corner grinding

Corner grinder is a very necessary and useful tool. Due to the fact that there are a large number of different nozzles for it, it can be used for cutting, polishing and polishing a wide variety of materials: metal, stone, wood, etc. In this article, I want to tell what disks for corner grinders are so that you can have an idea, what kind of work can be done by this tool. In addition to discs, consider various nozzles.

It is worth noting that for Bulgarians of different sizes you will require different sizes of discs. In addition, keep in mind that each circle or nozzle is designed for work only at a certain speed of rotation, so always consider this moment when choosing.

Abrasive discs for cutting metal

These circles are perhaps the most popular in use. After all, most users use an angular grinder just mainly to cut metals. Here, when choosing, the value must be given to the thickness of the disk, as well as to the one who produced it.

The thickness that varies from 1 to 3 mm affects the cut rate. The smaller it is, the faster the cutter occurs. In addition, sometimes it is necessary that the cut is as thin as possible, so the thick circle is not used. But it is worth noting that thin circles are spent faster than their thicker brothers. In this regard, if the cut speed is not particularly important to you, you can buy products by 2.5-3 mm.

As for the manufacturers, this moment is important due to the unequal quality of products from various companies. If you take the product from such eminent brands as Bosch or Makita, then they will be spent much slower. The price of such discs, however, is quite high. Therefore, one can do for one.Time work in an inexpensive option, the most popular of which is the products of the Luga plant.

Abrasive discs for cutting stone

This type differs from the previous composition of the abrasive, so it allows you to cut no metal, but a stone. Otherwise, all points relevant to metal disks will be fair for stone circles.

Choose cutting circles for angular grinding grounds for metal, the dimensions of which vary, you can like this:

  • Little diameter discs 115 and 125 mm. Suitable for small grilles;
  • Disks of medium diameter 150 and 180 mm are suitable for the Bulgarians of standard sizes;
  • Large diameter discs 230 mm. Suitable for very powerful, professional Bulgarians (power of 1,500 kW and above).

The internal diameter of the disk for all the above categories is the same and is 22.2 mm. The thickness of the circles also varies and is 1-3.0 mm. Large diameters of the disks for corner grinder suggest a large thickness and, accordingly, vice versa. This dependence is due to both the speed of rotation of the circle and the load on it. Do not cut a thick sheet of metal with a thin disk. As a result, in the process of work it can simply break it.

Various discs are used for various types of metal. For cutting body steel or aluminum, a thickness of 1–1.6 mm will be quite sufficient. And for thick metal channels, you should choose this parameter from 2.5 mm. The average consumption of circles of cuts per ton of metal (diameter 115 mm) is 73–171 pcs.

Diamond disks for corner grinders are used for cutting on stone, as well as slate, concrete, brick. Not a problem for them and ceramic tiles, paving stones, porcelain tiles. They are steel circles with a landing hole and a special spraying on the edge. The basis of spraying is diamond grains with a size of 0.2–0.8 mm.

Ordinary stone circles without diamond spraying are much cheaper. However, they cannot cope with sharp concrete or tiles due to the lack of cutting edge. Diamond circles are divided into the following types:

which, disks, suitable, corner

  • For dry cutting. The circle around the entire perimeter is divided into small fragments. Transverse recesses with teeth. This allows you to cool it faster and more significantly. Diamond teeth are made separately, after which they are soldered to the disk canvas. To do this, use laser welding and silver solder. It is important to remember that it is possible to work with such a disk continuously for more than 2 minutes. It is designed specifically for cutting brick, paving stones, concrete.
  • For wet cutting. Its purpose is the cutting of ceramic tiles and porcelain tiles. It has a continuous structure, and before cutting, the material must be moistened with water. The characteristic features of the circle are a flattened side edge and the additives of cobalt and bronze. Products with an admixture of bronze are well suited for cutting drywall, tiles, ceramic tiles. But the cobalt additive will help to cope with quartzite, granite, labradorite.

The landing size (inner diameter) for all diamond disks is 22 mm. Circles for wet cutting are often installed on tile cutters. Electric shoes with water supply. In this case, the diameter can reach 25.4 mm.

Buying the desired diamond disk for an angle grinding machine is very simple. Products are marked depending on which material is better to cut.

Marking of the diamond circle Material
Blue Marble, concrete
Grey Ceramics
Green Granite
Yellow Gypsum, tile
Orange Brick, plaster

Disks for corner grinders on wood are considered the most dangerous. When working with them, it is better to use circles with small teeth. It is also not recommended under any circumstances to remove a protective casing from them. Strong presentation during work can lead to serious injuries. Therefore, it is better to refuse the installation of such disks on an angular grinder of large size. The most suitable option is to combine them with a device for stationary fastening of an angle grinding machine.

Do not know how to remove a disk from a corner grinder, read our post.

The sizes of wood circles coincide with such metal. When choosing them, you should take into account the following features:

Briefly about the main thing

Corner grinder is a universal tool designed to work with various material, including for processing wood foundations. Grinding and cutting wheels on wood perform various functions:

  • Removal of the bark, pruning and sawing branches and trees;
  • Rough, black, final grinding of wood;
  • Surface polishing;
  • Rough and thin sawing boards, wood-fiber slab, wood-bruise.

But we must understand that this is all true only for those who have a work associated with wood processing is not earnings. Corner grinder is suitable just for small home worries. Repair, installation of the fence, replacement of the flooring. The necessary discs will help cut, clean, polish wooden materials and products. But if you have to work with a tree often, then a specialized tool will be much more practical.

Plus, we must always remember that the universal grinding machine belongs to increased danger. When performing work, it is imperative to comply with safety precautions.

A Grinding Disc That EATS Metal! Victograin VS Traditional Grinding Discs

Survatory circles for corner grinders, in turn, have their subspecies, such as:

The purpose of each of the types of disks usually corresponds to its name.

Among the grinding disks, four main subtypes are distinguished. Petal, wire, diamond and grinding wheels on a bake.Based basis (straight, T41 and plate profile, T27 profile).

  • The petal disk is made of sandpaper. Its main purpose is the elimination of an existing coating, such as the old paint, a primer or a layer of paintwork. Also, disks of this species are grinding wooden products.
  • Wire discs are used by masters to remove rust. They can also remove other types of persistent pollution by them.
  • Diamond discs are used for polishing work on stone.
  • Melt discs are made of plastic or rubber and used to polish metal surfaces.

Dimensions of disks for angular grinder

The first thing to take into account when choosing a circle is its size. Like the corner grinder itself, the discs differ in the outer diameter; Equipment types from 115 to 230 mm are produced. We will look at what disks for corner grinders for metal, wood and stone in dimensions, what features every variety has.

Disk diameter, mm Appointment
115 The smallest circles that are used for work in hard.To.Reach areas, processing of small.Sized blanks.
125 The most popular equipment for angular grinder, which is used for household and professional purposes. Most circles and Bulgarians are designed precisely for this diameter.
150 Discs of such sizes are an intermediate option between household and professional. Not too common, but irreplaceable in a number of tasks.
230 The type is used in repair and construction work to cut concrete walls, stone and brick. The high power of 230 mm grinder allows you to “pull out” large equipment, but as a result the tool is quite severe.

Despite the variety of sizes, the most common are only 125 and 230. The former are conditionally considered “household”, the latter. “professional”. But you should not perceive the separation too seriously: often on the construction site you can not do without 125 mm circles, the same is true and vice versa.

The corner grinding machine is actively operated in professional construction and everyday life. It provides users with a large number of advantages, however, the functionality of the corner grinder is determined in many ways to which the equipment elements will be involved. Removable nozzles are presented in a large assortment, they are distinguished by purpose, shape, size and material of manufacture. In the article, the master plumber will tell you what disks for corner grinders exist.

Circles for corner grinders are interchangeable elements. Performing work with different materials, it is necessary to understand their types. This will help to perform a qualitatively necessary operation. Circles are classified according to these parameters:

  • By purpose;
  • Type of work performed;
  • Constructive execution;
  • Type of cutting;
  • Manufacturing material;
  • Sizes.

By purpose, there are nozzles to perform work on metal, wood, stone, concrete, marble, etc. D. Manufacturers indicate the purpose in the marking, which is applied directly to the product itself. Many varieties are a universal tool, suitable for processing several types of materials.

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

  • Cut.Off. They are designed to perform cuts, black cuts, etc. P. A cutting disk has a cutting edge, which is a continuous circle or divided into segments.
  • Saw. The cutting edge has teeth. To trim many types of wood products and its substitutes, an angular grinder is used. To do the job, you need a saw disk. This variety of circles is designed to perform even, pure cut of a massive board, plywood, parquet, drywall. It is also suitable for laminate, wood-fiber slab, wood-bruise (including laminated), as well as selection of grooves in gas sulcate.
  • Rittle (grinding circles). Such nozzles remove the old layer of paint, varnish, primers from the surface to be treated, and grind.
  • Certificate. This is a variety of penderings. These include disk metal brushes. They can remove rust and other persistent pollution.
  • Petal circles. They are also referred to. The petal circle is used in the processing of products made of metal, wood, plastic, cleaning welds and burrs, removing rust, etc. P. The petal disk for corner grinders consists of plates, fixed over a circle, according to the principle of flower petals. Varieties: end, package, with a mandrel. The petal end of the corner grinder is designed for processing at an angle or ordinary flat. There are two of his subspecies. Straight and conical. Live LED LEC is needed when grinding on a large area. The conical circle circle is suitable when decorating seams, joints, etc. P. The package disk of the petal (folded) is also suitable for work on a large area. Feeding circles with a mandrel for corner grinder are used when working with cavities. They help to achieve the greatest accuracy of processing.
  • For cutting seams. They are used in the performance of seams in concrete, asphalt, etc. P. With such nozzles, grinder is suitable for this work.
  • Polishing. Such circles are used to final polishing surfaces. These include polishing interchangeable felt and felt nozzles for corner grinders with Velcro, as well as an emery circle.

Disks for corner grinder are made from several different materials. Each of them has its own characteristics. Types of circles for angular grinding machines:

    . They are made of steel, on which diamond spraying is applied. This type of nozzle cuts and polishes any metal, concrete, artificial and natural stone (including granite and marble), ceramics, glass. A saw diamond disk for an angular grinder provides the thinnest incision. You need to saw small cuts. A new type of diamond nozzles. Polishing circles on a flexible basis (“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 nozzle made of hard rubber with Velcro.

  • Cool. Circles of this species are also made of metal. They have a solder of high.Carbon molybdenum steels with chromium and nickel additives along the edges. They are used mainly when cutting metals, less often for wood. Corner grinder is suitable for working with many metals. There are carbular discs specially designed for thin, high.Carbon, stainless steel, aluminum.
  • Abrasive. The basis is dense waterproof latex paper with a reinforcing mesh or fiber. A layer of abrasive material is applied to it. Particles of aluminum oxide, silicon carbide, tungsten carbide or corundum. A ligament for an abrasive is a resin or polymer. A grinding fiber for a corner grinder is used complete with a support plastic plastic plate or rubber. It serves as an emphasis and cools the abrasive. Abrasive circles are used as cutting, reference or peeling. Fiber circle is suitable for wood and concrete work, non.Ferrous and ferrous metal processing. An abrasive is a zirconate or aluminum oxide, ceramic grain. The fiber circle is ideal for rough removal of old paint from the walls, facades and other surfaces.
  • Metal wire. Disk brushes from this material are used to remove rust and other types of persistent plaque.

Disks for corner grinders can be conditionally attributed to support plates. They are also called supporting or plate disks. Plates are made of plastic or rubber. They are used in combination with some grinding, polishing, food nozzles, sandpaper circles. The need to use the support disk must be clarified when buying a circle for angular grinder.

For the correct choice of a disk for an angular grinder, the external diameter of the nozzle should be taken into account, which should not exceed the maximum allowable value for a particular model angular grinder. Otherwise, unpleasant consequences may occur. Light power grinder simply cannot work with a large tool. The installation of a larger nozzle will require removing the protective casing, which is a serious violation of safety regulations during the operation of the tool.

When the corner grinder is operating, on which a too large circle is set, the linear speed will be overstated. This is primarily fraught with injuries to the master and the destruction of the abrasive disk.
