Ranking of the best diamond cups for 2022

The diamond cup is designed for grinding structures made of durable materials. It has the necessary hardness. Thanks to this, it is possible to process marble, brick, concrete and many other products. To carry out the grinding procedure, you will need a tool. A simple electric machine with a power of at least 1.5 kW is suitable. During the work there will be a very high concentration of dust.

Device

The diamond cup resembles a metal disc containing diamond coating. Due to this, it has increased strength and hardness. It is able to handle complex surfaces. Choosing a device is not easy. To do this, you need to know all the characteristics of diamond cups.

The device is divided into 2 groups. The first option includes circles that have a wide range of applications. The second type includes devices that are more whimsical and require special care. The working part is made of a bond and diamond coating. If the diamond wears off, the cup stops working effectively. In order for it to start functioning again, it is necessary to pass through it with abrasive material.

The same model can affect the processed materials in different ways. If it polishes granite perfectly, then on marble the efficiency will be much lower. You can ruin your work surface. It will appear a large number of various pits and irregularities. The product must be selected according to its intended use. So, models made for working on marble will not work in the case of granite. The diamond wears off quickly. Grinding will lose its effectiveness.

Also grinding cups have differences in the fraction of diamonds. The smaller this characteristic, the more “clumsy” the product is made. If it is necessary to level large ruts, then it is better to take a disc that has a rough coating. After processing, you will have to grind the surface again, but with a model with a finer fraction. If the surface to be treated has a flat base, then a part with a fine texture should be used immediately.

The working discs also differ in the quality of the diamond. Not always an expensive option will be more effective than a cheap one.But often a budget diamond will wear out faster, sharp notches will appear. The more expensive option will definitely last longer. However, being new, both cheap and expensive options can be equally effective.

Working discs have a different segment shape. The small distance between the fractions means a cleaner surface finish. Such models are recommended for grinding fragile materials. The procedure eliminates the appearance of chips and bumps. A large distance between the segments indicates faster processing. However, the quality of the sanding will be slightly worse.

Types of diamond wheels

The cups may have a different number of diamond segments. Depending on this parameter, several types are distinguished. Each model has its own narrow specialization and purpose.

Wheels with sections arranged in 1 row are light in weight and highly efficient, but they are very difficult to keep on the surface to be treated.

On some models, the segments are arranged in 2 rows. This design is ideal for roughing, it will quickly clean off all the roughness and irregularities, and carry out rough grinding. To bring the surface to be treated to an ideal state, you will have to use a nozzle with a different coating.

On sale you can see cups of the “square” type. They have a large mass and are produced for roughing the work surface. During grinding, a chipping effect takes place. This speeds up the process and reduces wear on the diamond blade. Most often used for roughening and surface preparation for spraying polymeric material. The "square" design leaves behind a rough plane. This has a positive effect on adhesion with other components.

Models are available for roughing very dense and strong materials. This design is called "Typhoon". With a small weight, it has a high margin of safety and wear resistance. Its shape is made in such a way that the cut particles are discharged at a high speed.

Manufacturers present models for finishing materials. This includes the segmented Turbo model. Nozzles are used in cases where it is necessary to achieve the ideal quality of grinding. Suitable for creating beautiful edges and chamfers on granite and marble. The cup is used by engravers-masons. They make curly stone monuments. By means of a nozzle it is possible to put beautiful bends on various products. On sale you can see devices with which precise processing is performed. Their diameter is about 100 mm. Such devices are wear-resistant and will last a long time.

Disks "Boomerang" are intended for finishing grinding. The work requires careful handling of the material. They are usually bought by professionals. The products have a variety of fine-grained diamond elements. This technology allows you to get a high quality end result.

Types of fasteners

The working disc must be installed on the electric tool. The most common types of fasteners are m14 and m22.2. Most grinders have such seats. Some manufacturers present on the market a tool with an unusual type of fastener (m16 or m24). This is done for a specific purpose. Owners of such machines will have to buy consumables only from this manufacturer. This fact can be devastating. After all, such products, as a rule, cost good money.

Products are produced in different circles.Before buying, you need to make sure that a cup with a certain diameter can be used on an existing grinder.

Scope of use

Diamond cups are in the first place when processing hard rocks and materials, they will help to carry out roughing and finishing of brickwork, slabs, concrete. They are ideal for polishing natural rocks such as granite or marble. First of all, rough processing is carried out. After that, do the final cleaning.

Diamond discs perform the following functions:

• cleaning of irregularities;
• removal of protruding elements;
• alignment of joints;
• seam polishing;
• smooth cleaning of the surface;
• finishing;
• elimination of old layers.

Good to know! When grinding, it is worth using a vacuum cleaner or pouring water onto the surface to be treated. This procedure will greatly facilitate the work. The amount of deposited dust will decrease significantly.

Handling advice

During grinding, moderate pressure should be exerted on the grinder. Pressing too hard can overheat the bundle, which will negatively affect further processing and reduce the resource of all elements. The pressure should also not be too low. In this case, the second layer of diamonds on the working surface of the cup may not open after erasing the first one.

If the product stops removing the processed layer, then you should not throw it away. Most likely, it is necessary to remove the upper bond and the new diamond layer will open itself. When working with granite stone, the disc often rubs and stops grinding. In this case, the best option would be to run a spinning cup over the plaster. The latter will act as an abrasive. The worn layer will be removed. After that, the disk will be able to process the surface further.

Selection Tips

The quality and speed of the work depends on the nozzle. In addition to the selection of technical characteristics, it is necessary to match the mounting holes on the grinder and the disc. The standard cup has a circumference of 125 mm. The diameter of the inner hole is 23 mm.

Of great importance is not only the power of the grinder, but also the speed. It is necessary to compare 2 characteristics. The instructions must specify the maximum degree of rotation. This indicator must match the characteristics of the grinding machine. Otherwise, the safety of the work being done can be called into question.

Usually, an adapter washer is included with the cup. With this simple device, the disc can be placed on different tools. Grinding is carried out, first of all, roughing, and then finishing. It all depends on which model the user has purchased.

During the purchase, you need to focus on the balance of the disk and its mass. And also look at the heat dissipation rate. Strong heat will shorten the life of the product. If you work under normal conditions, then it will last a long period without losing its original characteristics.
