Drilling large holes in a brick wall
How to drill a hole in a brick. How to drill a brick wall with a drill properly: sequential execution of the process
Certain skills and the right tools are required. Nevertheless, there is nothing complicated about it, and you can drill a brick wall yourself, without resorting to the help of craftsmen. Brick wall can be drilled in different ways, but when working, you should always consider that brick is a very strong material, and in order for its drilling to be successful, you need to use a cutting drill more durable than the brick itself.
There are many tricks in drilling holes in a brick wall, their knowledge will help to do all the work in the shortest possible time.
To drill a brick wall, you’ll need:
- Drill (powerful, percussion), you can use a peorator;
- pobedite glass;
- metal detector;
- a container filled with cold water;
- coring head;
- face shield or goggles.
Tools for carrying out the work
For the work different tools are used, the main ones: drill, peorator, screwdriver. There are nuances in using each.
The tool is suitable when you need to make several holes. An ordinary drill can be used. Plunging the pobedite drill into the body of the wall, sometimes it is necessary to break the concrete with a punch that matches the diameter of the hole. This is necessary when the drill begins to get stuck in the surface, bumping into too dense areas. The process is fairly time-consuming.
For more efficiency, universal drills with diamond tipped bits can be used. They are installed only on a regular drill or on a tool where the vibration function is disabled.
Impact drill and core bits with pobedite tips are used for large volume of work. They are designed for holes up to 12 mm. Drill suited for metal, concrete.
Peorator is a universal tool. It can be used to make a hole in the wall of wood, tile and concrete.
The tool has several functions. drilling, drilling with impact and impact mode. To make a hole, you need to select the right drill depending on the surface and do the work by selecting the mode.
The screwdriver is one of the most popular tools in repair and construction work. It can be used to tighten and unscrew screws, drill wood, metal, chipboard, plywood, tiles, plywood, lightweight concrete.
Which bits to choose?
A specific nozzle is used for each material:
- concrete, brick, stone. drill bit with carbide plate or pobedite;
- Tile, glass. cone drill bits with diamond coating;
- metal. spiral drill bit with a cylindrical cone;
- Wood, plasterboard. for different diameter holes, drills are used: pen drill, ballerina, screw drill, wood saw bits;
- Foam concrete. pobedite drill bits.
Is it possible to do without a drill and a rotary tool?
Make the hole without a drill and a torch, but not in a concrete wall. You need a flat borer or a drill bit.
The working end of the tool is applied to the place where the hole will be. On the opposite side of it, you need to make heavy blows, rotating the tool after each turn.
There are three ways to drill a hole in a brick wall: manual, electromechanical and automatic.
However, before you get to work, it is necessary to study the location of electrical wiring, because accidentally hitting the line for the trimmer wiring will not only damage it, but can also electrocute a person. Most often the wiring is vertical or diagonal to the sockets and switches. If in doubt you should use a special device to find hidden wires. Portable metal detector can help you find aluminum or copper wire, located no deeper than 1 cm.
Handheld drilling technology
In the absence of an electric tool, drilling holes can be done with a hatchet. To do this, the points are marked out beforehand by drilling with a hole punch. After that, a hammer is struck on the flat bar, which is placed against the wall at an angle of 90 degrees. Every three strokes, the hatchet is turned, and the remains of the brick is removed from the pipe. The hole is knocked out until it reaches the required depth.
The electromechanical process
Mechanical drilling is done with a percussion drill or a peorator, the process is the same.
To begin with it is necessary to determine the type (through, not through), depth and diameter of the hole. This is necessary for the right drill bit or drill bit. If there are difficulties in maintaining the same distance between the holes, it is possible to use a template. The stencil is made of plywood, chipboard, plastic and other improvised materials. To use it, you need to attach sandpaper on one side with double-sided tape or glue, then lean against the wall and drill.
Once the type and diameter of the future hole has been determined, a core mark must be made. The drilling process will be easier if you make it in the joint between the bricks. Notches with the core are made in order to fix the drill bit and facilitate its entry. When drilling with a drill, the tool must be kept perpendicular to the wall, gently pressing on it so as not to break the drill bit or drill bit. Periodically take the drill out to cool it down in a bowl of cold water.
If a hole with a diameter greater than 18 cm needs to be drilled, a drill with diamond bits is used. If they are not available, you can use a regular diameter pobedite drill bit. To do this:
- The place of the future hole is marked, a pencil outlines its contour.
- Drilling is performed along the outside of the line, the number of holes depending on the diameter of the contour. The diameter of the drill itself should be 0.8-1.0 cm, the step of the holes on the contour should be 1.0 cm. To do the job more accurately, even smaller drill bits can be used, but then the process will take longer.
- A chisel and hammer are used to cut out the drilled contour.
If you need to drill through a thick wall, you can do it in two steps: first, the drilling process is performed, as described above, on one side of the wall. Then, the center of the resulting hole is drilled through. marks out the required diameter on the other side of the wall, repeating the process.
Professional, expensive equipment is used for diamond drilling. It is desirable to have special skills and qualifications. With such a tool, the drilling process is fast, accurate, virtually silent, can be performed at various angles to a depth of up to 40 cm, and it forms an even hole, without chips or cracks. This method does not create much dust and dirt, as the tool is equipped with a nozzle to cool the drill and flush out the dust.

How to drill a hole in the wall under the pipe
Installation of any communications in the house, whether it be water or sewer pipes, or laying gas pipes, suggests their passage through walls or other floors. In this material master plumber tells in detail about how to make an opening for a pipe in the wall or other structural elements of the structure, and what you need to pay attention to during the work.
Usually drilled holes in the wall is performed to install fixtures (dowels, anchors, dowel-nails). Depending on the diameter of the installed fasteners, they can serve to suspend shelves, curtains, mirrors, fixing furniture. Diameter holes performed in this case rarely exceed 10 mm, most often 6 or 8 mm.When carrying out repair work, it is often necessary to transfer communications, in order to reduce the length of the lines often make a direct pass through the wall. The diameter of the hole to be drilled in this case will range from 15-20 to 30-40 mm. Occasionally there is a need to relocate the sewer pipe 50-100 mm.
In addition to through holes, it may be necessary to make blind holes. As a rule, electrical equipment such as sockets and switches are mounted in them.
Drilling requires the use of certain specialized tools:
Few people can be surprised by an electric drill. It is available in almost every house. Specialized carbide drills for concrete allow you to get quite an acceptable result.
The main difficulty of the task is that the drill can easily cope with homogeneous material. As long as there is a monolithic solidified mortar, no problems usually arise.
As soon as the tool meets gravel or pebbles in its path, the work stops. The drill simply glides over the obstacle at no load.
You can only continue to work if you crack the obstacle you encounter. A metal drift punch or a drill with impact function can be used for this.
Using a peorator makes it possible to drill more and do it more cost-effectively. This tool is somewhat similar to an impact drill and is capable of punching a hole in a hard surface. The main difference is the implementation of a percussion mechanism, it allows you to operate the equipment in a longer loading mode.
Length and diameter will directly affect the price. The larger they are, the more expensive the tool. Also, as the size of the workpiece increases, so do the power requirements for the torch. Low-powered machines are physically unable to reach the required opening.
Brick drilling process
How to choose a drill
As with any installation work, in order to make a hole in a surface, you need to know exactly what material it is made of. This will allow you to choose the right tool and the right type of drill. It is important to remember that the wrong choice can nullify your efforts or even ruin the equipment.
Two types of tools are used for drilling holes in the home:
The Peorator can be categorized as professional building equipment. It has a high performance and is thus considerably more expensive than a conventional drill. Not every owner has his own peorator, but the drill with the function of impact drilling is almost everyone has, and this device may well be used to create multiple holes in the brick.
If you plan to conduct extensive repair work with a large number of holes, it is better to buy or rent a peorator from any construction company. An ordinary drill can not withstand the load and become unusable.
When choosing a tool, consider the scope of repair work
If you decide to buy your own tools for work, when choosing the right equipment, you should proceed from the following indicators:
- the device must have a good motor with a power of at least 600 watts;
- it is desirable to have a motor speed regulator, because brick will require a maximum of 2500 rpm;
- the drill chuck must give the possibility to use drill bits with a diameter of 0.5 to 12 mm;
- impact drilling mode is mandatory. This function creates, in addition to rotary, also a reciprocating motion of the drill bit, which allows you to break down hard rocks, and the drilling process is much more effective;
- A special switch for the direction of rotation of the drill bit would be useful. You don’t need this feature for brick, but it will be useful for some other materials;
- handy chucks have a function of self-clamping of the drill without the use of a wrench. However, it should be taken into account that this feature significantly affects the cost of the tool.
If there is no percussion drilling function, drilling a single hole can take a long time. Without an impact motion, the edge of the drilling element cannot engage the rock, and you have to press the tool with great force when working. This causes increased stress on the inner workings of the tool itself. The drill bit begins to heat up quickly, which can cause it to collapse and remain in the hole.
Tools for work
Before drilling a wall, prepare the necessary tools and materials in advance. You will need:
- Electric drill or construction drill;
- fixing dowels;
- the drill bit made of pobedite alloy with a drill;
- cross or straight screwdriver, depending on the selected dowels;
- Gloves and goggles.
If you are using a drill without impact drilling you cannot use a drill bit. To work in addition to the tools listed above, you will need:
To drill a single hole, you will need drills of different diameters
- A core or metal puncher of similar diameter;
- a container with fresh water.
Preparing to drill
Before you drill the brick, you need to determine in advance the location of future holes and with a pencil or a marker, put the appropriate markings on the surface. It is important to remember that inside the wall may be hidden water pipes, cables or steel fittings, which are often used in the construction of multi-storey buildings. You must carefully examine the wall and make sure that the drill does not damage the communication systems and that it does not hit a metal bar.
If you started a grand repair, not knowing the location of communications and pipes, it is better to buy in a construction store portable metal detector and non-contact instrument to detect hidden wiring. These devices are relatively inexpensive, and it is highly discouraged to save money on them. If during drilling you damage the communications, their repair or replacement will cost you a lot more, so extra reinsurance does not hurt.
If drilling is performed in an already renovated room, you always want to avoid contamination or damage to the finish. This will not happen if you attach a shelf of the same material to the bottom of your stencil. Your wallpaper or paint will be protected and the drill dust will stay on this shelf.
Note! You can use an ordinary Tetra Pak (milk carton), cutting it in half. On one side you need to cut a little more with scissors, so that the paper does not interfere with the drill.
And a few more words on how to punch a hole in a large brick wall or arrange a small niche.
In the conditions of home repair it will be easy to cope with this task will also be able to pobeditovogo drill:
- Mark the contour of the hole on the wall.
- Make several drills along the planned line in 10 mm increments.
- Use a hammer and chisel to remove the unwanted material.
If you need to go deep and the length of the drill bit does not allow, do the job in two or more passes.
There are three ways to drill a hole in a brick wall: manual, electromechanical and automatic.
However, before you get to work, you should study the location of the electrical wiring, because accidentally hitting the fishing line for the trimmer wiring will not only damage it, but can also electrocute a person.
Most often the wiring is vertical or diagonal to the sockets and switches. If in doubt, use a special device to locate hidden wires. Portable metal detector will help you find aluminum wire or copper, located no deeper than 1 cm.

Drill a hole in a brick wall: wall preparation and marking
The preparatory stage in drilling is that you need to determine and mark on the wall the place on which you would like to see a hole. This is very important, because in the wall may be electrical wiring, damaging which you will not be in trouble. So use a metal detector to detect wires, or read the article “How to find hidden wiring” on our website.
In order not to run into communications in the wall, as a safety precaution, make a hole in their own hand at 15-20 mm, and if everything is normal, you can use the drill.
