To be able to perform various repair and construction work, the master must use the appropriate types of tools. For an angle grinder (angle grinder), or, as it is colloquially called, angle grinders, use various attachments. This allows you to perform many operations. Such equipment is used both for large volumes of work and for home repairs.
The largest share of the work performed by the grinder is cutting. To get an excellent result, it is necessary to use high quality diamond blades. To choose the right variety, you need to use the advice of experts, user reviews.
General characteristics of the tool
Bulgarian, like many other power tools, has removable elements. This allows angle grinders to carry out a wider range of work. A diamond blade for a grinder requires sharpening or just a timely replacement. So from time to time justyou need to purchase new replacement heads.
It is worth noting that there are simple and diamond blades for angle grinders. The latter option is stopped more often, as it is a more durable piece of equipment. However, depending on the amount of work, it is necessary to choose the characteristics of the discs.
The greater the load it will be subjected to, the more durable and expensive the tool. It is also important to initially consider the conditions under which diamond blades will be used. For each type of material, the appropriate variety is used.
Types of discs by edge type
Each cutting element of the angle grinder consists of a cutting (diamond) edge and a steel body. Depending on the type of work surface, there are 3 types of removable angle grinder elements.
Solid cutting discs allow you to get the job done without wasting material. This is important for ceramic tiles, marble. The cut is even.
Segmented diamond cutting disc has cutouts for cooling. Therefore, it is used for cutting concrete, brick.
This nozzle produces dry or wet cooling. In the first case, air enters the working surface through the grooves of the disc. The second option involves cooling with water or special substances.
Combination diamond cutting blades allow dry cutting or water cooling.
Disc usage
Depending on typeThe material that is processed using an angle grinder is distinguished by a diamond blade for metal, concrete, ceramic tile, wood or even glass. These removable elements can be universal or highly specialized. Therefore, when choosing, you should take into account the recommendations of the manufacturer.
For dense, hard materials, the cutting edge is made from softer steels. This allows the surface to release a new layer of diamonds when abraded.
There are three types of tools according to the method of application. This is a diamond blade for sharpening, cutting and grinding. For each operation, you must choose your own type.
Grinding will polish the surface to be treated. Slicing is most often used to separate ceramic tiles or other materials into pieces of the required size. Sharpening is carried out only when the grinder is fixed fixed. At the same time, drills, saw chains, etc. can be processed. To make work as safe as possible, it is necessary to strictly adhere to the manufacturer's recommendations.
Disc operation principle
The performance characteristics of a segmented or solid diamond blade depend on the cutting edge manufacturing technology. It differs in the principle of applying the substance, its granularity, as well as in the connecting element.
A layer of technical diamonds should not only be superficial. The entire cutting edge must have this material in its structure. In this caseoperating life increases significantly. This is especially important for the processing of foam concrete, brick.
With such processing, the diamond cutting disc does not so much cut as it grinds the surface. In this case, the working layer is also erased. During processing, the internal structure of the material is exposed. Therefore, it is important that the diamond coating is distributed throughout the thickness of the disc.
Diamond Segment Application Technology
Depending on the processing conditions, diamond coating can be applied by different methods. When choosing a disk, this must be taken into account. Otherwise, an incorrectly selected removable element will not work for long.
If diamond coating is applied to the surface using silver solder, this type of tool is used only when there is water cooling. Without it, such a diamond blade for a grinder quickly collapses.
If the coating is applied to the surface by laser welding, the product is considered durable. It is used for dry processing. This is a very durable form of technical diamond grit application.
When positive locking is used, the coating is applied during heat treatment with a binder. This disc option is used for all types of cutting.
What to look for when buying?
First of all, when choosing a tool, you need to pay attention to the dimensions. The inner diameter for the grinder is standardly 22 mm. If cutting with a diamond blade is performed using stationary equipment, it is possible thata tool with a diameter of 25.4 mm is required.
The outer size of the disc is 115, 125, 230, 350 mm. Depending on the type of work, you must choose one or another option.
Having decided on the dimensions, it is necessary to set the accuracy of processing. For a very precise cut, continuous spraying should be preferred. Segment varieties are suitable for concrete. It should also be noted that when processing the material by the dry method, it is necessary to stop the operation of the tool every 1.5-2 minutes. Therefore, the process is slightly delayed.
Discs for home use
In the conditions of doing home repairs with your own hands, you do not need to purchase expensive professional equipment. The volume of such work is usually small. Therefore, grinder discs used by home craftsmen may be less durable.
Their resource is quite enough for cutting a small amount of ceramic tiles or chasing a concrete wall. The cost of such a tool will be acceptable for any user.
Diamond disk, the price and quality of which are optimal for home use, is produced by domestic companies Zubr, Centroinstrument, Spartak. The cost of such products with a diameter of 230 mm is approximately 500 rubles per piece. Products of small sizes (up to 125 mm) will cost the user 200 rubles. According to users, this is a very reasonable price.
Professional equipment
Professional toolsubjected to long and heavy loads. Therefore, increased requirements are put forward in terms of strength. Stationary type equipment or portable professional models can use a diamond blade for sharpening, cutting or grinding for a long time.
At the same time, the possibility of continuous operation is a priority. This saves time and improves processing performance for large volumes of work.
Professional diamond varieties of tools are distinguished by their narrow specialization. Their cost is much higher than simple domestic removable angle grinder elements, but the durability is impressive.
The most famous manufacturers of such discs are Bosch, Distar. The starting price of their products is 2500 rubles. When carried out by professional builders, the cost of such diamond blades quickly pays off.
Operation
In order for diamond blades to serve for a long time and productively, it is necessary to properly process the material. Having picked up a suitable variety, you should follow the rules of labor safety. Bulgarian, judging by the reviews, is an unsafe tool.
Be sure to use a respirator and goggles. Sharpening is carried out exclusively on stationary, fixed types of equipment.
Before cutting, it is necessary to mark the place of future processing. Then a guide incision is made. It is used to process the material to the required depth.
As experienced users note,it should be remembered that the angle grinder with a dry tie-in must be stopped every 1.5 minutes, and with a wet one, water must be supplied to the disc in time.
After considering the diamond discs for sale, you can purchase the best option. Existing varieties must be selected in accordance with the profile of activity. If you plan to do work at home, it is not at all necessary to buy an expensive tool. But in the hands of professionals, high-quality durable discs will pay off very quickly. With proper operation, they will last a long time and productively (reviews confirm this). It is only necessary to follow the rules for working on such an electric tool.
