During the construction or repair process, a specialist has to drill large diameter holes in the walls, floor or ceiling. When arranging electrical communications, sewage, ventilation or water supply, this can not be avoided. In order to carry out all the actions as fruitfully as possible, use diamond crowns for diamond drilling.
This is a durable cutting element of manual or stationary equipment, which is suitable for both professional and home 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 crowns for diamond drilling are a cutting tool that allows you to make holes in different coatings. These include: concrete, brick, granite, reinforced concrete and all solid lining.
This is a removable drill element. Its edge has segments with a special coating of industrial diamonds.
A shank for fastening is located on the opposite side. Choosing diamond crowns for drilling concrete, ceramic tiles, be sure to pay attention to this.
Benefits
Diamond crowns for drilling porcelain stoneware and other coatings have many advantages over other types of tools. They have good performance. Therefore, they are used in their work by professional repairmen and builders. The special shape allows you to make holes of perfect configuration and a fairly large depth.
These removable elements do not cut, but crush the thickness of the material. In this case, shock vibration is not formed. 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
Existing varieties are divided according to the principle of precision cutting into two groups. The first option is used for homogeneous walls, floors or ceilings of medium strength. These are diamond crowns for drilling concrete, brick. But for reinforced concrete walls, this kind is not suitable.
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 KS or BS. They are characterized by high cutting ability. Efficiency depends on the type of edge coating. If you incorrectly approach the issue of choice, you have to pay a decent amount of money for a product that will be used quite rarely.
Cutting edge
The finished product of the presented variety is made by silver soldering or laser welding at high temperatures. They can also fill the thickness of the upper edge. As abrasion, new layers will be released.
This technology is important when drilling very durable coatings. These are 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 rate of abrasion of the coating, three types of matrix are distinguished. The first is the softest. Such a tool is applicable for drilling durable materials. The diamond coating erases quickly, which helps prevent edge contamination.
The average hardness of the matrix is suitable for ordinary concrete. Its hard varieties are intended for abrasive materials that can crumble. The rate of abrasion of the spraying is low. But the process is performed slowly. The 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 cost less.
Type of drilling
Two types of drilling are distinguished depending on the scope of actions of the repairman, as well as the type of equipment. It can be dry or wet. This indicator characterizes the type of tool cooling. The diamond core for wet drilling is designed for drilling large diameter holes. The design of the power tool allows coolant to be introduced into the cutting zone.
Today, special detergent compositions are used that effectively remove the fine fraction. Cooling also prevents the overheating of the drill and its quick failure. Liquids protect metal elements from wear and corrosion. It is especially important to use coolers in an industrial environment. This significantly increases productivity, reduces cost. Downtime is reduced. Net profit is growing.
For home use, dry-cooled options are suitable. Through special openings, air enters the surface. To remove the dust, use a special construction vacuum cleaner.
Shank
Choosing diamond crowns for diamond drilling, be sure to pay attention to the type of shank. For each type of electrical or stationary equipment, this part has its own characteristics.
For hand-held power tools that are used for domestic purposes, an SDS-plus shank is suitable. Such types are intended for drilling standard openings for sockets, arrangement of a water supply system.
If the equipment is characterized by high power, and the diameter of the holes is large, the shank is marked SDS-max. When drilling tiles, porcelain tiles or other durable coatings is required , the shock -free types have a BSP shank. They allow you to create holes of different diameters and depths.
Manufacturers and prices
Today, the cutting tool market provides a wide range of products. It is produced by foreign and domestic companies. Diamond core bits, the price of which is relatively high, are used in most cases only by professionals. This is a quality product that has the strength and durability. It provides high precision insertion.
These companies include 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. A new crown will not have to be purchased for a very long time.
Cheaper varieties are produced by domestic companies Alaton, Adele, and EuroPrice. For domestic purposes, their resource is enough, and the cost is significantly different from foreign products. For a standard length of 450 mm, the price starts at 4 thousand rubles. (for diameter 46 mm).
You should not buy too cheap, low-quality products. This will not only degrade the quality of the processing, but may also be unsafe. For domestic needs or professional activities, preferred companies should be preferred. Such products have appropriate quality certificates, other documentation of compliance with safety requirements.
Expert Advice
Choosing diamond crowns for drilling reinforced concrete, tile or brick, you should use the recommendations of experts. They advise using the technique only for its intended purpose. Otherwise, the quality of the action will be unsatisfactory.
For domestic purposes, the most popular diameter is 68 mm. It is this size that is needed for the plant.
If the spraying has worn off, it is not necessary to run to the store for a new copy. If the case is free from defects, it should be returned for repair. The master will be able to solder a new layer of diamonds on the cutting edge. It will be possible to operate it again. This makes the process of using equipment cheaper. For home use, its maintainability is a significant advantage. It will not take a very long time to spend the family budget.
Having considered the main characteristics of such a tool 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 basic qualities of the presented product. The effectiveness of the repairman’s actions and the durability of the cutting product depend on this.
