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

The grinder (technical name is an angle grinder, angle grinder) is used during home repairs and on construction sites.

The list of technological manipulations that it helps to carry out is long, but let’s talk a little about something else, namely: how to choose the right attachments and discs for an angle grinder.

They are selected according to their purpose (depending on the material and purpose of the work) and size.

The range of power tools in stores is large, but not everyone can approach this issue professionally. It is precisely these doubters and those who do not understand that our article is aimed at.

What kind of circles are there for an angle grinder?

Discs belong to the category of replaceable elements. Designed to work with various materials. Experts recommend that before you go shopping, you understand the classification of circles. All popular models of nozzles are selected based on the following parameters:

• type of work performed;
• appointments;
• type of cutting;
• design features;
• size;
• manufacturing material.

Based on their purpose, wheels are produced to perform the following work:

• on wood;
• for metal;
• by paint;
• on concrete;
• on stone;
• on marble;
• universal.

Based on the assigned tasks, consumables are divided into the following groups:

Disc sizes are standardized. A specific outside diameter presupposes a corresponding thickness and bore diameter. Manufacturers can deviate from the established rules only if they carry out an individual order. According to buyers, when choosing a product you need to take its technical characteristics seriously. Otherwise, a positive result will not be achieved.

Extra options

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

• 40–80 – pre-treatment;
• 100–120 – leveling;
• 180–240 – final grinding.

Flexible diamond polishing wheel grits: 50, 100, 200, 400, 600, 800, 1000, 1500, 2000 and 3000 (fine grits). The graininess is indicated by the markings on the back.

Diamond cutting discs come in four types:

1. Solid (“Crown”). They are designed for wet cutting only. The cutting edge is continuous. This type of circle ensures faster work completion and makes smooth cuts without chipping.
2. 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 making dry cuts.
3. Combined (“Turbo”). The edge of the disk has a serrated shape consisting of inclined grooves. This type of disc is universal, suitable for dry and wet cuts.
4. Turbo segment. Their edge is also serrated, but divided into segments, like a segmented disk. Suitable for dry cutting. The special shape improves performance.

When cutting many types of materials with a grinder (concrete, ceramics, etc.), a large amount of dust is generated. It is advisable to avoid harmful consequences for the person performing the work, as well as dust settling on surrounding objects. Therefore, the “wet” cutting technique is used. During work, make sure that the cutting edge is moistened with water, then there will be less dust.

On sale you can find wheels for angle grinders with a flange. The flange securely and quickly fastens the wheel, increases rigidity, reduces vibration, increases processing accuracy, expands the capabilities of the tool, allows you to process “dead zones” and flat corners.

Features of circles

Produced consumables for grinders differ in characteristics, functionality, number of teeth, degree of sharpening, and average price. Everyone's selection criteria are different. It is worth determining for yourself which option is most suitable for completing the tasks. The main types of products produced are:

1. Abrasive. They are distinguished by their versatility. The scope of application is wide. Able to perform any operations on sharpening and grinding surfaces. A positive result is guaranteed. Also intended for polishing.
2. Diamond. Quite in demand among professional craftsmen. Type of spraying – diamond dust. The main properties are durability and strength. The quality of the cut is excellent. They can handle not only metal, but also concrete and stone. An indispensable thing for those who are engaged in construction work at a professional level.
3. The main component is tungsten carbide. Belongs to the category of new products. Innovative technologies are used in production. It is quickly gaining popularity among domestic builders due to its strength, good quality and durability. Used for finishing and sanding operations.
4. Twisted cones. The main purpose is to peel and sharpen tools. Work with stone and metal coatings. They will quickly and efficiently remove the old layer of paint or other coating from the surface. Equipped with bowl-shaped nozzles made of durable steel. There is a twisted metal wire around the perimeter. Based on the purpose of the tool, you can choose either thick or thin wire.

Purpose of discs and attachments

Grinder circles differ in purpose for:

• cutting;
• roughing
• grinding;
• sharpening

Cutting discs

The most common task performed with a grinder is cutting various materials. The choice of tool material also depends on what material will need to be cut.

1. Metal cutting. The metal cutting disc is made from crystalline alumina corundum, as well as from synthetic corundum called electrocorundum. The main color of metal cutting wheels is blue.

2. Cutting stone and concrete. To cut stone, you should choose a disk made of another abrasive material - silicon carbide. This abrasive easily cuts white brick (silicate) and slate. But to cut red brick, some types of concrete or ceramic tiles, this wheel material is not suitable. Stone discs are available in green.

3. Cutting ceramic tiles, red brick, porcelain tiles and concrete. A diamond disc is already used for these purposes.

   
   This attachment is made of metal; an abrasive mass with diamond chips is applied to the cutting edge. The picture above shows a segmented saw blade designed for dry cutting of material. All-metal discs require water cooling during operation.

4. Wood cutting. Although there are saw blades for wood on sale that are no different from circular saw blades, it is better not to use them for safety reasons. When working with such a tool, the user often suffers serious injuries due to jamming, rebounding, accidental slipping of the tool, etc.

Therefore, if you are still going to use a saw blade on wood, you should adhere to safety precautions. The grinder must have a protective casing and handle installed, and the user must wear a protective mask or goggles. In addition, you cannot cut materials with this tool that are not intended for it.

The safest are considered to be wood discs with a chainsaw chain installed at the end. If the tool jams, the chain remains in place and the disc rotates idle, which reduces the likelihood of injury to the user.

Roughing

If it is necessary to remove a layer of paint or other application, as well as rust from any surface, brushes are used. They come in disc form or in the form of a bowl with built-in metal wire.

The wire in these nozzles can be twisted or loose. Its thickness can also vary. The thicker the wire, the coarser the stripping, the stripping disc or cup-shaped attachment is used, and vice versa.

Grinding

Sanding discs and attachments are used for grinding and polishing various surfaces (metal, wood, plastic and others). Often a flap type grinding wheel is used for grinding. It consists of many “petals” made of sandpaper. The grit of sandpaper can be selected based on the required type of processing (finishing or roughing).

The sandpaper can also be attached to the nozzle using Velcro. Such a tool is screwed onto the angle grinder spindle.

For polishing surfaces, special wheels and attachments are produced that look like felt pads or fabric discs.

Sharpening

To sharpen a tool, sharpening machines (sharpeners) are usually used. But if you don’t have the latter, but have a grinder, then you can purchase a sharpening (grinding) wheel for it, which can easily sharpen almost any cutting tool.

The main difference between grinding wheels and cutting wheels is their thickness (at least 5 mm).

Grinding wheels for grinders

They are considered equipment for angle grinders. The main area of ​​use is working with metal. Available in medium-grain and coarse-grain. The choice depends on the intended operations. The product is used in the following cases:

1. To remove scale.
2. For preliminary surface preparation for welding work.
3. Chamfering.
4. Cleaning up the weld.

The product belongs to the universal category. You can work with it on a plane, along an edge or on corner joints. Can handle any materials (metals and alloys), simple and complex shapes. Proven technologies are used in production. The result is the creation of a multifunctional abrasive tool with expanded functionality and scope of application.

Working with the consumable is easy and simple. No special skills, experience or ability are required. A few minutes are enough, and the treated surface will become clean, even and smooth, ready for further operations. All defects are eliminated quickly and efficiently. We are talking about removing protrusions, removing surfacing, removing scale and other defects that may form during welding.

Without a grinding wheel, it is impossible to remove burrs and tarnish. To make a grinding edge, you need to set the disk at an angle of 35 - 45 degrees relative to the surface.

The diameter of stripping consumables is similar to that of cutting consumables - from 115 to 230 mm. Thickness – from 6.10 to 20 mm. The product is durable. No reinforcement is used during manufacturing. The size of abrasive particles varies. The larger they are, the faster the work goes. Particularly large grains are able to free the surface from scale and rust in a matter of minutes.

How to choose the right product

The question of where to buy wheels for angle grinders is not difficult. The market is filled with appropriate products for every taste and budget. It is advisable to visit a specialized retail outlet. There, the sales manager will help you decide on a purchase if any difficulties arise, introduce you to the assortment, and give practical advice. You can order products online in an online store, after first reviewing reviews regarding the supplier of the product and its integrity. Otherwise, you may encounter cheap, low-quality Chinese counterfeits.

What to look for when choosing cleaning consumables? The material of manufacture plays a big role. Specific disks are purchased to perform various tasks:

1. Made from silicon carbide. The scope of application is grinding materials that have low tensile strength, brittleness and high hardness. We are talking about glass, ceramics, cast iron, porcelain.
2. Made from electrocorundum. Suitable for processing iron, steel (including chrome-plated) and cast iron.
3. Elbor. Strength is not inferior to diamond. Designed for operations with high-alloy steel. Perfectly sharpens blades.
4. Abrasive. The combination of grains into a single mass occurs through the use of a special binder. There are two options - ceramic and bekelite. The first is intended for interaction with carbide structures, the second is more suitable for limestone, concrete, granite, marble, brick.
5. Diamond. Involves fine grinding and finishing of high-hardness materials: glass, ceramics, cast iron.

The diameter of the disk is also important. On sale you can find 125 mm and 230 mm models. Thickness varies from 4 to 10 mm. It is worth paying attention to the size of the abrasive particles. Products are produced with large and medium grains.

Which company is better to purchase a product depends on personal preferences. On store shelves you can choose quality products from both domestic and foreign manufacturers. It is worth keeping in mind that strong and durable products cannot be budget-friendly. Whether it is worth choosing disks with additional functions depends on the tasks assigned to the equipment. It is advisable to choose consumables with an ideal price-quality ratio. This will help you quickly achieve a positive result.

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.

Rules for replacing a wheel on an angle grinder

There are no eternal consumables. Over time, they all wear out and require replacement with new ones. It's quite easy to do. You need to perform the following manipulations in turn:

1. De-energize the instrument.
2. Lock the spindle using the locking button located on the body.
3. Insert key.
4. One hand holds the latch, the other turns the nut.
5. The circle is removed.
6. A new disk is being installed.
7. Fastening operations are carried out in reverse order.

Please note that the disk must be installed correctly. The side with the markings should be on the outside.

Actions when a disk is jammed

This problem occurs quite often, so it should not be ignored. If such a situation arises, professional builders recommend taking the following actions:

1. Use gas wrenches. Manipulations must be carried out confidently, but with a certain accuracy. Otherwise, the stopper may be damaged. It is necessary to free yourself from the remnants of the circle in order to get to the lower flange. Just use pliers. Then, using keys, clamp the lower and upper fasteners and turn them in different directions.
2. Disassemble the gearbox. This method is used when the latch has become unusable. The disc can also be removed using pliers. The fastener and cover are removed. The shaft is secured using a vice. The fastener is unscrewed using a key.
3. The circle is shrinking. Parts of the disk are deleted. A metal sheet is taken with a vice, the angle grinder is turned on and the remaining abrasive is ground off on the end of the sheet.
4. The nut is warming up. You can't do without a blowtorch. You can use the services of a hair dryer or a gas burner. The heated flange can be unscrewed using the supplied wrench. It is worth thinking about safety precautions and carrying out manipulations with gloves to avoid touching a hot surface.
5. Use WD-40 lubricant. The composition is applied to the junction of the flange and shaft. A five-minute interval is maintained so that the lubricant gets inside. Then try to unscrew the fastener.
6. Cut the part using a hacksaw. It is imperative to hold down the stop button.
7. Knock on the middle of the nut. You can use a hammer drill with an impact function. In this case, the stopper state must be active. A few movements are enough and the fasteners will be removed.

Types of grinding machine breakdowns

Because problems can arise while working with hand-held power tools, you need to understand how to deal with such situations. Most often, hitches in using a grinding machine occur precisely because of the wrong choice of disk.

Angle grinders can cut stone, concrete, metal and other durable materials, so the sharp cutting part can be fatal to humans. Hold the wheel tool correctly to avoid contact with your hand. Before work, make sure that the protective cover is installed. Wear protective gloves and an apron to prevent sparks.

The risk of breakage is inherent in every abrasive disc. To eliminate this situation, before installing the disk on the angle grinder, check its functionality. You can stop or reduce the risk of disk rupture by being aware of the limitations of a particular drive. We are talking about the maximum permissible speed. You should only use a sanding disc that is in good condition. Also, the nozzle must comply with the expiration date, since otherwise safe operation cannot be guaranteed.

Kickback of the grinder can occur if the angle grinder catches the material while cutting. This happens due to the wrong drive or speed being selected. Stop the power tool and make sure the speed is appropriate. Poorly installed circles can also cause severe kickback. Make sure that the material is worn out and change the discs on time so as not to risk your health.

With strong kickback, you lose control of the tool, which can be torn right out of your hands. When using angle grinders, you can produce a lot of sparks. Monitor the situation to stop the tool in time. You must be confident in the safe operation of the angle grinder, excluding the presence of flammable or explosive substances in the working area. Many angle grinders are electric, and you should be aware of the risks associated with portable electrical equipment. Check the tool before use, then proceed to work.

If you doubt the functionality of the grinder, it is better to contact a specialist or, if you have experience, fix the problem yourself. For example, even high levels of vibration can cause negative effects on your health. Also, dust released when cutting metal or grinding is considered harmful to humans.
