When installing various systems and communications in homes, you often have to deal with the fact that you need to make a hole in the wall for piping or wires through it. To do this, you need to drill it, and then expand the resulting opening to the required diameter. This is a very time-consuming process that requires considerable effort and time from the contractor. Therefore, in such a situation, it is best to use diamond crowns.
They are hollow cylinders of a certain diameter, on one end of which there is a pin for fastening to a drill, and on the other side special diamond segments are soldered. The cutting surfaces are located at a certain distance from each other and are the part that plays a leading role in further drilling.
Diamond crowns can cope with making holes in the wall many times faster than standard tools. At the same time, the costs of physical labor and time are minimized, and the channels obtained in this way are perfectly smooth and neat.
Some builders use diamond crowns for concrete, not only to conduct communications through the walls, but also to arrange seats for the further installation of sockets and switches. To do this, they drill the wall to the depth necessary to install parts without going through it. This results in a neat recess. For such work, special diamond crowns are usually purchased that match the diameter of the device to be mounted. Usually this is a standard nozzle for an outlet and for a junction box.
Since this tool has to work with abrasive material, it is often dull, but it can be sharpened in the same way as drills. However, it should be borne in mind that diamond segments soldered to the crown are very strong and at the same time very fragile. They are not intended for shock work and do not tolerate overheating. Therefore, do not knock on the crown to remove residual concrete or cement. When sharpening or intensive work, it should not be heated. There are also diamond crowns that have a cooling function. They are supplied with water or an emulsion, which helps protect the working segments from overheating during operation. However, such a device can be very impractical and expensive.
The practice of using this type of device has shown amazing results. This did not go unnoticed and was the reason for the development of this area. Therefore, today in the shops of construction tools you can find diamond crowns for metal, concrete, wood and even devices for working with granite. They were often used even in production, which avoided the use of a drilling or milling machine in some of the operations required by the process.
Thus, diamond crowns are necessarily included in the tool kit of modern builders, as they help not only speed up the installation process, but also greatly facilitate it.
