Crown for concrete pads for concrete: description

When performing a major overhaul in a room, the electrical wiring is often replaced at the same time, which can not be avoided without an element such as a crown for concrete pads. Since new switches and sockets are required for new wiring, holes of the required size are drilled under them.

Concrete has a distinctive strength and is difficult to work with, especially when it is necessary to create technological holes. To speed up the process and simplify the work, use a crown for concrete 68.

This cutting tool is operated when a perforator or drill is used. Drilling is also possible on brick and reinforced concrete. Drilling must be carried out in compliance with safety regulations, thus it is possible to obtain symmetrical holes for the juniper.

How the crown works

The creation of technological holes is a difficult task for the master because of the high strength of concrete, which involves the use of a special tool. Drilling with a drill or perforator with a conventional nozzle is not always effective. The way out of the situation are special diamond crowns for podrozetnikov.

Outwardly, the tool resembles a small piece of pipe, on one side of which there are cutting segments made of hard-alloy material. They also fall into the base of the wall when creating podrozetnikov.

A special flange is located on the other side of the crown, it connects to a drill or a drill. The tool used must have a large head diameter and high power. Basically these are devices with electric or pneumatic drive.

The simultaneous use of a crown and a centering special drill, fixed on the common unit of the device, is possible. It prevents the wrong move of the cutting tool.

In the presence of diamond spraying along the edges of the edge, the cutting characteristics and durability increase at least twice. The standard diameter of the crown for the jar is 68 mm and is suitable for most switches.

Carbide-tipped carbide elements

A competent selection of parts will increase the speed and efficiency of work. Particular attention is paid to the reliability and high power of the tool used.

A drill bit for drilling holes in concrete has certain design features. Today, you can find several types of crowns, the most common is a version of carbide metal. This alloy is presented in the form of a special soldering, which determines the durability and reliability. Despite such characteristics, if the crown hits the reinforcement during the drilling of reinforced concrete, the tapping simply flies out.

Diamond Spray on Crowns

In addition to different technological characteristics, there are differences in price. The diamond-coated tool is better than the others, making it easier to work with solid materials. Such a crown for podrozetnikov on concrete makes it possible to create holes with minimal physical and time costs. Despite its relatively high cost, it gained wide distribution due to the possibility of cutting reinforced sections.

Carbide-tungsten tool

Such a crown is the most affordable and economical option. It can be used for drilling foundations of concrete, ceramic tiles and bricks. Due to the versatility of such a tool, the required work can be done without changing the nozzles, besides convenience, this gives an economic benefit, as there is no need to purchase an additional tool.

This crown for concrete holders for concrete has a special design and a hexagonal special shank, which is located on the back side, due to this drilling is performed with a tool, which makes a power of not less than 800 watts. Such a device, unlike a diamond one, can not be used for work on a reinforced concrete base, because when the cutting parts come into contact with the reinforcement, it will fail and will be unsuitable for use.

Dimensions of the cheeks

The template diameter of the pad is 68 mm, but larger products are also found. In particular, bulbs are used for the switch and a socket with a diameter of 75 and 70 mm. This should be taken into account when choosing a crown. For a good fixation in the wall, there should be free space for the alabaster mixture. So, for example, under the diameter of the podrozetnika in 68 mm, it is desirable to use a hole with a size of about 72 mm. If you have any doubts or questions, please contact the seller before purchasing. It should be noted that the solution of alabaster is characterized by the rapidity of setting, so do not hesitate to install the jar.

Under the standard size of the jug, most of the sockets and switches are produced. But there are also devices with a different diameter, so even at the design stage it is necessary to finally determine the materials used and only then buy, focusing on the available budget and wishes.

Assembly

Particular attention is paid to the preparation of cutting tools. The crown is assembled in accordance with the operating instructions, otherwise unforeseen situations may occur during operation. The assembly begins with the preparation of the drill bit. It is inserted into the socket and fixed tightly with the appropriate bolts. Then, under the drill, the cup is fixed on the thread. Each element of the instrument must be firmly seated in its place. If the assembly is poor-quality or incomplete, it is possible to break down individual elements during operation and to obtain an unsatisfactory result.

Drilling of concrete

After complete assembly and verification of the crown, you can start working. It is desirable to make the main holes with a perforator or a powerful impact drill (in its absence). Using a conventional drill is not recommended, since the process in this case will become ineffective and take too much time.

In a concrete base, certain marks are placed in designated places, later a centering drill is exposed on them. Then you can start drilling the concrete with a bit. To do this, a drill is installed on the previously made marking and the tool is turned on. It must be kept as flat and tight as possible.

Since during drilling in the air a large amount of harmful dust is dispersed, it is necessary to stock up with special construction glasses and a respirator in advance.

The cutting tool is reset when the work is completed. First, the nozzle should completely cool down, otherwise the cutting solder may fall off when it is removed. From the puncher, the cutting edge is removed, from which the existing dirt and dust are removed. It should also remove its middle part, it's easiest to do with an ordinary hammer or a metal chisel. After that, the crown for concrete pads for concrete is fully ready for further use.

What you need to know

It is undesirable to purchase cheap attachments. They do not have any advantages, except attractive cost, and after the first drilling process holes usually fail.

It is important to observe safety precautions when working with instruments of this type.

Although concrete refers to fairly strong materials, it can be made holes in the shortest possible time without significant effort with the help of a properly selected cutting tool.

To increase the service life, it is possible to make holes in small diameter concrete around the perimeter of the mounting of the juniper with a drill. Due to this, the area of connection of the wall surface and the cutting elements of the crown will decrease, which in turn will speed up the work and protect the tool from damage.
