Choosing a crown cone for drilling holes for a socket

If you think that the hole for the socket. “a piece of cake”, you can hollow it out with anything, then you are obviously stuck in the last century.

Today, there are special drill bits, which allow you to make sockets quickly, accurately and as neatly as possible.

They are actively used not only in primary construction work, but also in cosmetic repairs.

Imagine how an expensive tile will look after the “peeling with something”? And it often happens that you need a new socket after the tiling work is finished.

And here a properly selected drill bit will leave a perfect hole, with the right diameter and depth, without chips and cracks.

I think that this article will be relevant for both construction professionals, and for the amateur repairers.

After reading it, you will get all the information you need about drill bits:

I will tell you how and what to drill in order not to spoil the appearance of the wall and the crown itself.

Safety precautions

Concrete drilling is an injurious form of construction work, so it is important to comply with safety regulations. The requirements for personal protection are as follows:

    Use plastic goggles, as there is a high risk that particles of detritus, which are part of the cement, could bounce off the wall. A mask should also be worn for this purpose so as not to damage the exposed skin on the face. Wear a respirator or dust mask. Concrete cutting is accompanied by the release of large amounts of dust. Small particles of cement precipitate on mucous membranes, causing throat friction and breathing problems. To protect your skin from dust, wear a protective suit or old unwanted clothing and a hat. Use of cotton gloves is recommended. They will protect your hands from possible burns and minor scratches, allowing you to hold the device with more confidence without accidental slipping.

Also, before drilling holes, it is important to study the utility plan for the room to avoid hitting electrical wiring and gas pipes. If there is no such a pattern, the walls are checked with special instruments. If this is not possible, concrete work must not be performed.

When making holes in the wall, people must be kept away from the working area within a radius of 3 meters. If the socket is made at a height, drilling is carried out on stable scaffolding. Using a torch without a firm base under the feet of the worker is prohibited.

Hold the power tool firmly with both hands when using it. Increase the speed gradually, not leading up to the maximum values.

Failure to follow the listed safety rules is fraught with the risk of equipment breakdown in the easiest case. It is not uncommon for workers to be seriously injured or killed if they do not handle the power tools for carving concrete correctly.

Safety precautions

Concrete drilling is an injury-prone type of construction work, so it is important to follow the safety rules. The requirements for personal protection are as follows:

    Use plastic goggles, as there is a high risk that debris particles blasted by the cement will bounce off the wall. To do the same, wear a mask to protect exposed skin on the face. Wear a respirator or petal mask. Concrete drilling is accompanied by the release of large amounts of dust. Fine cement particles settle on mucous membranes, resulting in a sore throat, difficulty breathing. Wear a protective suit or old, unwanted clothing and a hat to protect against dust. The use of cotton gloves is recommended. They will protect your hands from possible burns and minor scratches and allow you to hold the tool with more confidence without accidental slipping.

Also, before drilling holes, it is important to study the plan of communications in the room, so as not to touch the electrical wiring and gas pipes. If there is no such a scheme, the walls are checked with special devices. When it can’t be done either, concrete work is abandoned.

When piercing holes in the wall, keep people away from the work area within a radius of 3 meters. If the socket is made at a height, drilling is done on stable scaffolding. The use of the rotator without a solid base under the feet of the worker is prohibited.

When using electric tools, hold them firmly with both hands. Speed should be increased gradually, without reaching the maximum values.

Failure to follow these safety rules is fraught with equipment failure in the easiest case. Often workers are seriously injured or even killed if improper handling of power tools for concrete threading.

With a drill bit for undercuts

If you have no idea how to drill a hole for a socket, buy a special drill bit in the store. It facilitates the work process and is inexpensive. Its base is a pin, which is attached to the peorator (screwed on the flange), and it looks like a piece of pipe with a diameter of 68-80 mm. At its end there is a thread, thanks to which the product is fixed. The other end is an alloy cutting element. By the way, sometimes parts of such crowns are coated with diamond dust to increase their service life. The third part is the drill itself. Then the construction is fixed with a screw. The drill helps to center the core bit when drilling socket holes. The cost of such a nozzle is high, but justified, because the thing is literally indispensable for large and small repairs.

What you need to know before you start

Strangely enough, we focus on the theoretical aspect. The most important thing when performing the described by us operation. is to know all the safety rules and the variety of tools.

Safety rules

The first and most important thing we will talk about is safety. Remember that diamond drilling holes in concrete is a very dangerous procedure.

Therefore, it is necessary to follow certain guidelines for its implementation:

  • Remember to wear protective gear (helmet, goggles, respirator and protective clothing). Remember that concrete dust is very harmful to health.
  • A special instruction states that before starting work, you must remove people from the work area (within 2.5 meters from the facility).
  • Working at a height (more than 1.5 meters) with the concrete drill without a solid base is prohibited. This is stated in the Industrial Safety Regulations and the Norms and Regulations. So you have to build trestles or scaffolding.

  • Before starting work, carefully study the plan of communications. It is necessary in order not to bump into wiring or gas pipes. For safety (the plan does not always show the position of lines of communication correctly) use a “wire gauge.

Tip: most locating devices can not determine the exact location of wiring hidden under decorative materials. Therefore it is highly undesirable to drill in such a case.

  • It is extremely dangerous to drill through the joints in a block house. Very often the builders hide the wiring between the blocks. For this reason it is forbidden to cut reinforced concrete with diamond discs in these places.
  • Use only a two-handed tool. Increase the RPM as gently as possible. Otherwise there is a high chance of an accident.

Choosing the right tool

Now turn to the choice of tool. Drilling holes in concrete for sockets can have varying degrees of difficulty, depending on the surface. For this reason we have to choose the right tool.

  • The wall is not more than 30 cm thick.In this case, a drill of 350W or more with an SDS chuck will suffice. The diameter of the shank must be at least 1 cm.

The monolithic walls will require a powerful tool

  • Concrete monolith of cement grade 400 and above. In that case the tool must be more powerful, e.g. SDS Max. Diameter of the shank must be about 18 cm.
  • Professional drilling of reinforced concrete (and other heavy constructions). An impact wrench of at least 1 kW is also required.
  • Finally, if the need arises to make a hole more than half a meter deep, the most powerful tool in the field comes to the rescue. We are talking about a power drill, a tool with a capacity of 5-8 kW. Any kind of wall can be drilled with it.

Important: because of its high power the power drill cannot be connected to the standard power supply (1-2 phase). Therefore, it is practically not used in domestic conditions.

Probably many people may think that you should just buy the most powerful tool and that’s it. However, not everyone knows that the price of such devices is very high. Of course, if you can afford it, you can give preference to such a tool, and it will significantly speed up the process of performing the task at hand.

What are socket outlets for?

When sockets are handled carelessly, they often fall out of the wall if they are poorly fixed in it. For example, if you jerk the plug sharply or take it out by the cord without holding it, the “socket” will soon become wider, and the socket will begin to fall out of it. Subrosetnik will help save from such a situation.

When installing outlets in a new wall, it is recommended that you first drill a hole for a socket, then proceed to fix the sockets. When installing the sockets used standard podrosettniki, therefore, openings under them also do standard. Company “Sphere Plus” performs these and many other electrical work, conducts electrical work in a wooden house, etc.

How to make a hole in the tile for the socket

It is better to cut a hole in the tile before gluing it to the wall, tightly pressed against the board under it. This is done for two reasons:

  • Behind the glued tile it is difficult to lay a wire. The exception is the situation when the socket is in the upper row of tiles;
  • Tile is fragile, so it is possible to drill in it only with a drill in the “rotation without impact” mode, and so only drywall and alabaster partitions are drilled.

Therefore, it is necessary to accurately mark the centers of the boxes in the wall and in the tile, taking into account the gaps between the tiles. In addition to calculations, you can do the following:

  • Start drilling into the tile;
  • After the appearance of a through hole, put the tile to the place of installation;
  • Make a mark through it on the wall;
  • Drill a hole to install the mounting box;
  • Finish cutting the hole in the tile;
  • Glue the tiles to the wall and install the mounting box.

Or just cut a hole with a larger diameter, and fill the gaps with putty.

Tip. Sockets and switches are square (double sockets are rectangular), so if they are in the corner of the tile, you can make a square cut with an angle grinder. Subsequently, it will be closed with a decorative cover.
