Boring holes in concrete crowns

When overhaul in apartments or houses with concrete walls in most cases, try to completely change the electrical wiring, and in this case, can not do without such an important component, as the crown on the concrete.

clear that new wiring means installation and new outlets with switches to install the necessary holes a certain size.

As is well known, concrete is distinguished by its incredible durability, and work with them is problematic, especially when the need to do any technological holes.

It is in order to facilitate the work of the master, and speed up the process if necessary to make holes in concrete technology for various applications, and is designed for concrete crown.

This cutting tool works using a drill or punch.Drilling can be made both in reinforced concrete and a brick.

Drilling is carried out necessarily in compliance with safety regulations and provides a smooth hole Escutcheon given size.

Currently acquire the crown Concrete can be virtually any specialty store without any problems.

device crowns

As you know, the concrete has good strength characteristics that makethis material is very popular in the construction of residential houses.

Meanwhile, high strength concrete makes it very difficult to work with him.

If necessary, make technological openings Enclosures, master is faced with quite a serious problem and need to use a special tool.If

to drill using a punch or drill with a nozzle in the form of an ordinary drill, it is possible to be busy for a long time and as a result do nothing.

Drilling holes for socket

In this case, simply can not do without special bits for concrete, which has a diamond-coated.

In view of the cutting tool is a small segment of the tube, the edges of which on the one hand have cutting segments made entirely of carbide material.

When podrozetnik drilling these segments and penetrate into the concrete foundation.

At the other end of the crown is a special flange, by means of which the mounting of the crown to the cylinder or gun drill.

tool used for drilling concrete using the crown should have a sufficiently high power and large diameter of the head.

Usually Escutcheon for drilling in concrete, a tool is used with a pneumatic or electric actuator.

In addition, further to the crown on the concrete a special pilot drill bit can be used, which is recorded in the general assembly and the tool allows you to avoid the wrong turn the main cutting tool.If

crown will further have rough edges on the spraying edge, the cutting of its durability and ability to increase several-fold.

for more efficient and faster work should correctly choose the crown on the concrete, on the basis of its type.

Special attention should be paid and the choice of instrument, which should have sufficient capacity and reliability.

Kinds and types of crowns

drill bit for concrete, intended for openings Enclosures, has some design features.

Currently, there are several different types of crowns with honey are some differences.The most common drill bit is made only from the solid alloy.

This alloy crown can be seen as a special soldering, which determines its strength and durability.

Set crowns

should be noted that if the drilling is carried out in reinforced concrete and a crown at some point gets to the valve, such soldering, probably just fly.

addition to various technical differences, these crowns are different and their value.It is easiest to work with concrete, if you use the tool with a diamond-coated.

drill bit, which has a special diamond coating, you can quickly and simply make the necessary holes Enclosures with minimal physical effort.

Its distinctive feature is the high cost, however, the cutting tool if necessary and allow to penetrate the reinforced sections of the wall.

more budget and affordable option - it is a tungsten-carbide drill bit.

This cutter can be used for work with concrete bases, and to work with bricks and even ceramic tiles.

property of crowns - to drill a variety of types of bases - allows the necessary work without changing the nozzles that are not only convenient, but also cost-effective because there is no need to purchase an additional tool.

This drill bit has a special design and due to the special hexagonal tail located at its rear side, the required drilling can be carried out using a drill, the power of which should not be less than eight watts.

Compared to the diamond, the crown type is not designed to work with reinforced concrete base and in contact with its cutting segments on the valve, simply fail and become unsuitable for further use.

Dimensions crowns and prepare them to work

Before going to the store for a crown for Enclosures, it is necessary to accurately determine their size and diameter.

If the crown will be acquired properly done in the concrete wall of the hole may be technical or too big or too small.

most common size, which is considered to be of a standard, has a diameter in sixty-eight millimeters.

It was under him and produced the majority of switches and sockets.

However, the market can find the outlets and switches and other diameters, and therefore still at the preliminary stage of the repair should be precisely defined in order, what materials will be used and, on this basis, to acquire all necessary.

should also pay special attention to the preparation and cutting tools to work.

crown assembly must be carried out in accordance with the instructions, otherwise at work can cause a serious injury.

Before starting work, it is recommended to carefully study the instructions that comes with the crown.crown assembly begins with the preparation pobeditovye drill.

It must be inserted into the holder and securely, using the screws.Further, the cup should be strengthened under the drill itself is threaded.

All crowns elements must sit tight in place and do not hang out.

If the assembly is not complete or is not quality, is in the process can break down individual elements of the crown or cause a serious injury.

drilling process

When the drill bit is completely assembled and tested, you can proceed to the actual work on the concrete.

do basic work best with the gun, and in his absence you can use the powerful impact drill.

not recommended to use ordinary drill, as in this case, the work will be ineffective and a huge amount of time will be spent on it.

To start on a concrete base should be made at predetermined locations identified tags, which will subsequently be exposed centering drill.

After that you can start and to the very core drilling of concrete foundation walls.To do this, set the drill to a pre-made label and start drilling.

tool should be kept tightly and evenly as possible.

conduct work on a mandatory basis should be in a respirator and glasses special construction, as when drilling in space formed a lot of harmful dust.

At the end of the work with the concrete should be properly cause the cutting tool to its original state.

To start the nozzle should be given time to ensure that it is completely cooled off, otherwise if its dismantling could just fall off her cutting soldering.

For this the cutting nozzle is removed from the punch with her remove all cement dust and dirt.

should also get its middle part and make it easier to just using ordinary metal chisel or hammer.

Thus, the cutting attachment will be prepared for further use.

not buy cheaper options, such as China-made for selection of cutting heads for working with concrete.

Despite its affordable price, in most cases, they fail after the first drilling of technological holes in the wall.

Also, when working with the cutting tool should be mandatory to adhere to security requirements.

Despite the fact that concrete is strong enough material to do it the necessary technology holes correctly picked up a special cutting tool can effortlessly in no time.
