Diamond crowns for diamond drilling: overview, types and manufacturers. Diamond Crowns for drilling concrete

In the process of construction or repair, a specialist must drill a large diameter hole in the walls, floor or ceiling. With the arrangement of electrical communications, sewerage, ventilation or water supply, this can not be avoided. To all the actions to conduct the most fruitful, use diamond crowns for diamond drilling.

This is a sturdy cutting element for manual or stationary equipment, which is suitable for both professional and home-made craftsmen. Many varieties allow you to choose the best option for existing conditions. Each owner wants to reduce their costs from the family budget. Therefore, the choice should be made deliberately.

general characteristics

Diamond bits for diamond drilling are a cutting tool that allows holes to be made in different coatings. These include: concrete, brick, granite, reinforced concrete and all hard lining.

This is a removable element of the drill. Its edge has segments with a special coating of technical diamonds.

On the opposite side there is a shank for fastening. Choosing diamond crowns for drilling concrete, ceramic tiles, be sure to pay attention to this.

Benefits

Diamond crowns for drilling ceramic granite and other coatings have a lot of advantages over other types of tools. They have good indicators. Therefore, they are used in their activities by professional repairmen and builders. A special shape allows you to make holes of an ideal configuration and a rather large depth.

These removable elements do not cut, but crush the thickness of the material. This does not generate shock vibration. This allows them to be used even for load-bearing reinforced concrete structures. This is one of the main advantages. This is what makes the presented equipment so popular. One of the qualities that prolong longevity is maintainability.

Varieties

The existing varieties are divided according to the principle of cutting precision into two groups. The first option is used for homogeneous walls, floors or ceilings of medium strength. These are diamond bits for drilling concrete, bricks. But for reinforced concrete walls such a variety does not fit.

If there is a metal reinforcement in the thickness of the wall, the material is relatively thin or there is a lining on the base, another option is used. This type is marked with a CS or BS. They are characterized by high cutting ability. The effectiveness depends on the type of edge coating. If it is wrong to approach the choice issue, you will have to pay a decent amount of money for the product, which will be used quite rarely.

Cutting Edge

The finished product of the presented variety is manufactured by silver brazing or laser welding at high temperatures. They can also fill the thickness of the upper edge. In the process of abrasion, new layers will be released.

This technology is important when drilling very durable coatings. It is more often professional diamond crowns for drilling tiles, natural stone, porcelain stoneware or even glass. For reinforced concrete, the spraying of segments is combined in a certain sequence.

According to the abrasion speed of the coating, three types of matrix are distinguished. The first one is the softest one. This tool is suitable for drilling durable materials. Diamond coating is quickly erased, which helps prevent edge contamination.

The average hardness of the matrix is suitable for conventional concrete. Its hard varieties are designed for abrasive materials that can crumble. The abrasion rate of sputtering is low. But the process is slow. A solid matrix is suitable for drilling limestone, foam concrete, brick. The cost of each variety is also quite different. For soft coatings, the crown will be cheaper.

Type of drilling

Depending on the scope of actions of the repairman, as well as the type of equipment, two types of drilling are distinguished. It can be dry or wet. This indicator characterizes the type of cooling of the instrument. A diamond core for wet drilling is designed for drilling large diameter holes. The design of the power tool allows the cooling liquid to be introduced into the cutting zone.

Today, special detergents are used, which effectively remove the fine fraction. Cooling also prevents overheating of the drill and its rapid failure. Liquids protect metal elements from wear and corrosion. It is especially important to use coolers in industrial conditions. This significantly increases productivity, reduces costs. The number of downtime decreases. Net profit is growing.

Suitable for domestic use are dry-cooling options. Air enters through special openings to the surface. To remove the formed dust, use a special construction vacuum cleaner.

Shank

When choosing diamond drill bits for diamond drilling, be sure to pay attention to the type of shank. For each variety of electrical or stationary equipment, this part has its own characteristics.

For the hand power tool, which is used for domestic purposes, the shank type SDS-plus is suitable. Such types are intended for drilling of standard holes for podrozetnikov, arrangement of water supply system.

If the technique is characterized by high power, and the diameter of the holes is large, the shank is labeled SDS-max. When you want to drill a tile, porcelain stoneware or other durable coatings, unstressed types have a BSP shank. They allow you to create holes of different diameter and depth.

Manufacturers and prices

Today, the cutting tool market provides the widest choice of products. It is produced by foreign and domestic companies. Crowns for diamond drilling, the price of which is relatively high, are used in most cases only by professionals. This is a quality product that has strength and durability. It provides high accuracy of the frame.

Among these companies are Bosch, Husqvarna, Tyrolit, Cedima, Rothenberg. These are market leaders, leading the development of improved technologies. Their development allows to increase the quality of finished products. The cost, depending on the size, can reach 70 thousand rubles. This is a one-time cost. The new crown will not have to be purchased for a very long time.

The cheaper varieties are produced by domestic companies "Alaton", "Adel", "EuroPrice". For household purposes, their resource is quite enough, and the cost is significantly different from foreign products. For a standard length of 450 mm, the price starts at 4,000 rubles. (For a diameter of 46 mm).

Do not buy too cheap, low-quality products. This will not only worsen the quality of processing, but can also be unsafe. For domestic needs or professional activity, preference should be given to proven companies. Such goods have corresponding certificates of quality, other documentation of compliance with safety requirements.

Recommendations of experts

Choosing diamond crowns for drilling reinforced concrete, tiles or bricks, you should use the recommendations of experts. They advise to apply the technique only for its intended purpose. Otherwise, the quality of the actions will be unsatisfactory.

For household purposes, the most popular diameter is 68 mm. It is this size that is needed for the juniper.

If the spraying has worn off, it is not necessary to run to the store for a new copy. If the case is not defective, you should return it for repair. The master will be able to solder a new layer of diamonds on the cutting edge. It can be used again. This makes the process of using the equipment cheaper. For home use, its maintainability is a significant advantage. It will not be necessary to spend money for the family budget for a very long time.

Having considered the basic characteristics of such tools as diamond crowns for diamond drilling, you can choose their optimal variety. The correct type will allow you to perform all the actions correctly, and the service life will be the longest. Every master should know the main qualities of the presented product. On this depends the effectiveness of the repairman and the durability of the cutting product.
