Rating of TOP-15 discs for grinders: review of the best grinding, metal cutting and diamond models

Typical disk sizes for angle grinders

All interchangeable wheels have standardized sizes, so for any model of grinder you can choose a suitable size disk, even if it is “non-original” (from another company). The table below shows the typical dimensions of cutting discs in terms of thickness, diameter of the circle and seat:

The larger the diameter of the circle and its thickness, the thicker the products it can cut. Please note that the diameter of the disc should not exceed the permissible size for a particular grinder model. Thus, a 230 mm disc cannot be placed on an angle grinder with a maximum allowable wheel size of 125 mm. Such actions will force you to remove the protection, which is a violation of safety regulations, and will lead to an increase in the linear speed of the cutting edge, which is why the disk can simply fly apart during operation and injure the operator.

The diameter of the seat in most grinders is 22.23 mm, 13.20 mm is less common, and the diameter of 32.00 is relevant only for large disks. Pay attention also to the linear speed of rotation of the disk. For example, if the disc’s marking indicates a speed of 13,000 rpm, this means that your grinder must also produce such revolutions in order to work with it.

You can understand what material the nozzle can work with and what its typical dimensions are by looking at its markings on the front side. If you came to the store and picked up the disc, you can see the following:

We would like to note that sometimes the buyer may encounter non-standard nozzle sizes, and this may apply to both diameter and thickness. This often happens when purchasing “no-name” disks of unknown manufacture. We still recommend buying branded discs, since unknown ones are erased faster, and in the end you have to pay more.

Cutting discs

Cutting discs are most often used when working with an angle grinder. The following nozzles are distinguished by purpose:

• For metal. Such cutting wheels are made from electrocorundum or crystalline corundum. In this case, a bakelite bond is often used inside the product. Depending on the thickness and size, the disc can cut metal profiles, stainless steel, heating pipes, etc. GRAFF GADM 115 10 is one of the representatives of inexpensive metal discs.

• For stone and concrete. Circles for cutting stone and concrete are made of silicon carbide. Please note that the disc is intended for relatively “soft” materials, such as white brick and slate (harder ones will require a diamond wheel).

• For ceramic tiles and concrete. This attachment is designed for cutting paving stones, ceramic tiles, red bricks, cutting strips for gating, etc. The disc itself is made of metal with diamond chips applied to the cutting edge. There are solid all-metal and segmented discs. The first ones are intended for wet cutting (cooling with water), as they become very hot during the process. Segmented ones are convenient for dry cutting, and they are the most popular among diamond blades. Here, for example, is a high-quality, durable segmented disk Makita B-28086 for cutting concrete and stone products.

• For wood . Discs for processing wooden structures are made of tungsten carbide or metal with abrasive coating. The first ones are designed for cutting hard and soft wood, plasterboard, gas silicate and MDF. The second one can also cut metal and even wood with nails (but this needs to be checked experimentally). Bison Professional 36859-125 is just such a representative of the “nail saw”.

• Universal. These attachments can cut almost all types of materials (for wood, it is better to take a direct-use attachment). In particular, they are convenient to use when you have to cut different materials in one working day, and you don’t want to waste time changing the nozzle. Universal models even cut reinforced concrete. However, they are often quite expensive, and sometimes it is more profitable to buy two disks for different types of materials being processed. Of the good universal circles, we can recommend Wolverine 100125, which is suitable for both wet and dry cutting.

Roughing

It’s worth mentioning right away that roughing and grinding discs go hand in hand, and in many stores in the “type” parameter of the attachment it may be written: “roughing grinding disc.” In our article we will divide this “couple” into two types. Peelers in this context are an attachment for freeing the structure being processed from the outer layer, for example, from rust. There are the following peeling attachments:

• Cord brushes. Cord brushes are disc or cup-shaped. Disc ones are convenient for cleaning vertical structures, for example, a tubular fence, and cup-shaped ones are used for cleaning horizontal surfaces. So cord brushes are very convenient for cleaning a car body after welding or removing rust. Here is an average-priced brass cord brush STAYER 35125-150:

• Roughing discs. Sanding discs, like cord brushes, can be flat or cup-shaped. They are intended for cleaning welds and preparing metal surfaces for grinding.

Grinding

Grinding wheels are used for polishing concrete, metal and wooden surfaces for painting or priming. Attachments for circles can be made of sandpaper, felt and even felt. In turn, the design of sanding wheels can be petal or flat (put on a wheel).

Each grinding disc has its own grit size. It is selected depending on the work being performed. Below is a table for selecting wheel grit depending on the type of grinding:

Encoding

The circle specification is encoded in four characters, Latin letters and numbers:

• the first letter indicates the material of the abrasive chips: AS - white electrocorundum, it is suitable for working on stainless steel, because the alloy contains practically no chlorine, sulfur and iron, which increase the cutting temperature; A - electrocorundum; C - silicon carbide - such circles are used to cut tiles and stone, but not metal;
• number - indicates the number of abrasive grains per unit area. The higher the number, the smaller the particle size. For cutting steel, larger grains are used - 24, 30; for working on soft non-ferrous metals, smaller ones - 60 or 40;
• the Latin letter is the hardness of the ligament. The first letters of the alphabet are the softest letters, the further from the beginning the harder. The softest bonds are selected for processing the hardest metals! You need to know this important ratio when choosing consumables for an angle grinder. During cutting, worn particles fall off and new ones, not yet dulled, come into play. If the bond is too tight, the cutting disc becomes “greasy”: it heats the metal and makes cutting difficult. At the same time, a circle with an overly soft bond wears down faster;
• the last Latin letter (or pair) is the name of the binding material, most often bakelite. Denoted as BF.

To summarize: how to choose a disc for an angle grinder?

To properly buy a disc for an angle grinder, you need to:

• Know the maximum size of disks that your angle grinder can handle. You cannot take disks larger than the device allows.
• Know the maximum speed of the grinder . The higher the rotation speed of the angle grinder, the smaller the disk size it can work with.
• Processed material . There are discs for wood, metal and stone. There are universal ones that can cut almost anything.
• Socket size . The size of the wheel seat must correspond to the same parameter in the angle grinder.
• Manufacturer . Do not buy frankly cheap discs or unknown products like hot cakes in the school cafeteria, and the savings will be minimal.

Selection by size

The outer and inner diameters of the circle are indicated on the main surface of the consumable. There are 9 standard external sizes from 125 to 500. The indicator is selected taking into account the class of the angle grinder. It is strictly forbidden to work with a larger circle. Only for large professional tools can you purchase consumables of any diameter.

The inner or bore diameter must match the size of the drive shaft. Most shafts are produced with a diameter of 22 mm, so 22.2 mm is an almost universal mounting diameter. Both sizes must fit the instrument model!

Instead of an epilogue

An analysis of the modern Russian market for cutting wheels for angle grinders revealed that the lower segment is the most popular and potential buyers prefer to sacrifice wear resistance for the sake of a high-quality, but short-lived cut. This segment is tightly occupied by completely different manufacturers - domestic, Western, and Asian. The middle segment is the most unclaimed, which is due to the low need for it among semi-professionals. At the same time, the professional and premium segments are also in demand, however, only for a very narrow circle. Basically, consumers are large specialized organizations.
