How to drill a brick without a hammer

How to drill a brick

During repairs it is often necessary to hang cornices, pictures, or even a hanging cabinet on the wall. And for this, in turn, it is necessary to drill a wall, sometimes made of brick. Drilling masonry is recommended with some experience in such work. You will also need the right tool. including properly selected drills, the cutting edge of which is made of a material that is harder and more durable than the brick.

Drills for brick

Ordinary drills, designed to work on metal, will not help drill a brick wall. precisely, the hole with their help will be made, but in this case, the brick will act as a sharpening stone, and the drill will quickly blunt.

The most efficient way to drill holes in bricks is with drill bits that have a cladding of the so-called “pobedite”. The peculiarities of the special alloy consisting of different proportions of tungsten and cobalt are such that drills made of it do not require pre-sharpening for work with hard surfaces. With the help of such a tool it is easy to drill holes in brick for dowels for shelves and other interior elements.

Also for drilling holes in bricks, drills with diamond coating (diamond powder electroplated on the metal in 1 or 2 layers) are often used. Due to their use the result of the work will be obtained even faster, but such drills cost more than pobedite, and the choice of diameters and lengths they have much less.

information about diamond drills and core bits can be found at http://www.stroy-res.The brick drill bit can be used to make a hole, but in this case, the brick will act as a sharpening stone and will quickly become blunt. Drills with increased m of diamond chips on the cutting surfaces are in great demand. Such coatings are applied by diffusion welding in a vacuum.

Before you start the repair, you need to buy drill bits of the appropriate diameter. as a rule, for most jobs 6, 8 and 10 millimeters will be enough. For diameters larger than 30 mm one can use not a drill and a drill, but a special core drill rig that makes it possible to make a hole in a brick wall rather quickly. If it is necessary to drill to a greater depth, a drill with rounded edges is used, which increases the wear resistance of the tool.

Features of drilling

In addition to the right drill, the master will also need the presence of a torch or, as a last resort, an impact drill. Such tools drills not only rotate, but also hit them.

During the work, you should not forget about the following features of drilling bricks:

  • Pobedite and diamond drill bits will dull after about 20-30 holes have been drilled with them;
  • while drilling, the drills should occasionally be immersed in water to prevent them from overheating and to ensure better adhesion;
  • To drill longer, you should not drill more than 200-300 rpm into the brick;
  • During the work certain precautions should be taken. Because the drill bit heats up to very high temperatures, you should avoid touching it. It is also not recommended to work without safety glasses to prevent dust and brick particles from getting into your eyes.

Preparation of the wall

If you want to drill holes in a brick wall, you must first determine exactly where they will be. Make sure that there are no electrical wires or sewer pipes in the area. We can be helped by a special detector, which can easily be found in almost every DIY store. The points where the holes should be located can be marked with a pencil, this helps a lot. We also have to reach a level to make sure that we keep the level.

Drill bits are used for drilling in brick, concrete and stone. They allow holes from 3 mm to even 35 mm in diameter, are heavy and have a single spiral with one groove. The cheapest large format drills available on the market are usually made of stainless steel and are suitable for both brick walls and drywall.

If we want to be able to drill holes in harder materials as well, such as reinforced concrete or compact stone, we must invest in harder sintered carbide models. We should not save too much when looking for the right exercise. If we choose a solid product of a well-known brand, it certainly will not be damaged after the first use. Many manufacturers say that durable drills can work well for several or even several years, depending on how often they are used.

How to drill through concrete with an electric screwdriver without a torch for 1000. 5 New Year’s Gifts

How to drill through concrete without a torch with an electric screwdriver for 1000. The neighbors have been drilling nonstop for 15 years. One of the most talented neighbors starts drilling with a low-powered drill on January 1 in the afternoon. Drills briefly, but persistently. I can feel in my spinal cord that it is not powerful enough. But no matter what, he tries to break through the wall Against his background, the neighbor upstairs, who rolls cast-iron balls in the morning, is just an angel, a cast-iron angel. The obsession to drill into a concrete wall without a torch has been with me for the last decade. About five years ago I was a witness to a workman drilling a granite step in the neighboring store. I was certain that they were drilling without a baffle, or the step would have just cracked But how they did it, I had not guessed. It dawned on me this summer when I wanted to make a sculpture out of cobblestones at the cottage. The idea was simple. to connect the stones with a stud by drilling a hole in them. In Leroy I came across a budget drill bit for ceramic and glass. Cost 60. Took a couple to try them out. Tried to drill through limestone, small rock at the country house. Flushed with success I began to drill a granite boulder. Drills long enough, drilled to a depth of about 3 cm. I am satisfied with the result. The ceramic feather drill bit drilled the stone faster than a diamond drill bit. I will now allow myself a diversion. Go to the question about the cordless electric screwdriver. I have always wondered how many screwdrivers I should have. Lately I have been using a screwdriver a lot and when it is not at hand, I feel uncomfortable. I need one electric screwdriver in the country, and another one at home, so I don’t have to carry the device here and there. At the end of this dacha season, one of my screwdrivers broke Dexter 18v. It seems the engine is dead, the screwdriver worked 4 years, I drove it a lot. In 4 years it has logged at least 300 hours. I did a lot of sanding and drilling with it, I guess I overdid it. I should have thought what kind of power tool I would buy to replace it. I complained to my friend about the electric screwdriver. And oh my god, my friend offered to sell him the broken electric screwdriver. He even offered 1000 for it, but in the end we agreed on 1500. Now Santa Claus just had to bring me for the New Year with a new electric screwdriver. Added 1200 and Santa Claus brought me a new DEKO electric screwdriver in a case with two lithium batteries 12 V / 2 Ah. DEKO model DKCD12FU-Li 063-4094 exact name. According to the description, the torque is 28 Nm, I thought that’s not enough torque. I really liked the new screwdriver, especially the case. In December the stars were aligned. I had an urgent need to hang a couple of showcases for orders and medals on the wall. I was too lazy to take out the torch. I remembered the magic drill, the ceramic feather drill bit. If I drilled a granite stone in the summer house, I could definitely drill a wall, I thought. And the new electric screwdriver had to be tested. I got a new drill bit, 5 mm. In half an hour I had drilled eight holes I’m sorry, holes. Drill bit burned, because I drilled at maximum speed (1350 rpm) and forgot to wet the drill bit. It took me about 30 seconds for one 20 mm deep hole. It took longer to mark than to drill. Could not be happier that it seems I drilled faster than my neighbor. And I drilled very quietly. You should have drilled with the electric screwdriver at 300 rpm on the first speed and moistened the drill bit more often. We hammer in a plug with a diameter of 6 mm, screw in a screw and hang the jewelry case. It’s like a museum at home.

I have gained invaluable experience. An old, broken tool (an electric screwdriver) is realistic to sell for a substantial sum. The best gift for a troublesome neighbor is a ceramic drill bit. All the neighbors will be in favor. Silence is the best gift for January 1. DEKO electric screwdriver. not a bad budget gift. A showcase for medals is an original gift for your acquaintances, if they still have their grandfather’s awards.

Rules of the job: tips

Safety rules and general guidelines must be followed when working with tools:

  • 1) Protect your respiratory system when working, dust is harmful.
  • 2) If you work outside, you need to put fences at 2.5 meters.
  • 3) When working at heights above 1,5 meters use a scaffolding or a sawhorse.
  • 4) When working with the tool, it is necessary to turn on the speed slowly and in no case you can turn it off when it is in the body of the wall.
  • 5) When drilling through the plaster, you must carefully study the plan of communications, so as not to touch anything.
  • 6) It is strictly forbidden to drill through the decorative coating.
  • 7) Choose the right drill bits for each surface.
  • Wet the drill bit with water so it does not overheat.

What can be used to seal up a large, drilled wall?

Unnecessary holes in the wall can be sealed with a special mortar. It provides strength and durability. Select the composition should be selected depending on the area and type of defect.

With the help of putty you can level the surface, including concrete. There are several varieties of putty:

  • cement-based. used for exterior and interior finishing, suitable for concrete. Durable and moisture-resistant. Dries for a long time and often meshes, requiring re-application;
  • gypsum putty is used in dry premise, it is not waterproof and is afraid of temperature difference. Does not crack when applied, so you can apply a thick layer at once;
  • acrylic. finish. Applied in a thin layer, so it is suitable for small defects.

None of the mixtures are used for filling in through holes.

Assembling foam is a universal material. Available in one-component (used without preparation) and two-component (when used with a construction gun or mixer).

The foam expands during application and fills the space in question. Cures and gives a good density. Deep holes can be filled.

Repair compound is suitable for repairing large defects. Has good adhesion, frost resistance, strength and durability.

Deciding to make a hole, carefully read the rules and recommendations. Choose the tool depending on the surface composition and the drill bits. If you are not confident in your own skills, then trust the work to professionals.

How to drill a brick wall

During repairs, communications or redevelopment, there is a need to make a different number of holes in the walls. The tools and drilling techniques will differ depending on the wall material. Before you drill a brick wall, it is recommended to take advantage of some practical tips, since such a strong material as brick sometimes requires a special approach.

Necessary tools and their choice

The wrong choice of tool and the type of drill will not only not get the desired result, but can ruin the equipment. Two types of equipment are used for drilling bricks. a peorator or impact drill. The right choice of a drill, first of all, is its power. The minimum power of this tool should not be less than 600 watts, and the minimum number of revolutions. from 2500 rpm. It is better if the mechanism has a reverse rotation of the drill and the ability to smoothly regulate the power. Drilling holes in bricks should be done with an impact drill, since walls made of this material are very resistant to static loads, and are only subject to impact with loads of a dynamic nature. If you drill with an ordinary drill, the process will be long and inefficient, because the edge of the drill will not be able to engage the internal structure of the brick. This can cause tool overheating and drill breakage.

In addition to the use of electrical equipment, it is possible to use a hand-held tool, the so-called jumper. It is a tube with teeth on the end, with which the hole is penetrated by physical force of a person.

The following tools will also be needed:

In order to drill holes in the brick wall effectively, it is necessary to use drill bits with a certain diameter, made of carbide material. They differ from conventional drills in that they have a diamond or pobedite cutting edge. For hole depths up to 15 cm, drill bits with a diameter of 0.6 or 0.8 cm can be used. The maximum diameter of the hole that can be drilled through a brick is 1.5 cm.

Victory drill for brick walls

If you want to drill a through hole with a much larger diameter, it is better to use a drill bit that is mounted on a peorator and an impact drill. The size of the auger depends on the depth of the hole. If you need to drill a hole in the wall width of 60 cm or more, to speed up the process and its efficiency, it is recommended to use drills with the same diameter, but of different lengths at different stages of drilling, for example, to start with a drill length of 15 cm, and at the final stage. a length of 50 cm.

The maximum drill hole diameter can be up to 2.8 cm.

To install boxes for outlets, switches, you need to create a niche. In this case, the drill bits on the peorator are used, which are made of strong steel and allow to obtain holes of large diameter. Drilling with crowns is performed without using the percussion function, and their choice depends on the diameter and number of teeth.

The crown on the peorator

  • Dowels for fasteners
  • Dowel screwdriver
  • Safety glasses
  • Tank for cooling water
  • A drilling core for marking with a drill.
  • Hammer
  • Victory glass
  • Metal detector

TIP FOR DRILLING INTO MASONRY WITHOUT A HAMMER DRILL | LEARN WITH ME | DAY 15 OF 16

Drilling technology

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 the electrical wiring, because accidental contact with 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 outlets and switches. When in doubt, it is worth using a special device to locate hidden wires. A portable metal detector will help locate aluminum wire or copper wire no deeper than 1 cm.

A portable metal detector can help locate hidden utilities

The technology of manual drilling

If you don’t have an electric tool, you can drill with a hatchet. For this purpose, the places are pre-marked 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 flat borer is turned and the brick debris is removed from the pipe. This is how the hole is knocked out until it reaches the right depth.

Electromechanical process

Mechanical drilling is performed with an impact drill or a rotary hammer, the process is the same.

First you need to decide on the type (through, no through), depth and diameter of the hole. This is necessary for the right drill or drill bit. If you have difficulty maintaining the same distance between the holes, you can use a template. The stencil is made of plywood, chipboard, plastic and other materials at hand. To use it, you need to attach sandpaper on one side with double-sided tape or glue, then lean it against the wall and drill.

Once the type and diameter of the future hole has been determined, you should mark with a core. The drilling process will be easier if it is carried out in the joint between the bricks. Core notches are made in order to fix the drill bit and facilitate its entry. When drilling with a drill tool must be kept perpendicular to the wall, gently pressing on it so as not to break the drill bit or drill bit. Periodically, the drill needs to be taken out to cool in a container of cold water.

If you want to drill a hole with a diameter greater than 18cm, use a drill with diamond bits. If they are not available, you can use pobedite drill bits of usual diameter. To do this:

  • The place of the future hole is marked, tracing its contour with a pencil.
  • Drilling is done along the outside of the line, the number of holes depends on the diameter of the circuit. The diameter of the drill bit itself should be 0,8-1,0 cm, the spacing of the holes on the contour should be 1,0 cm. To do the job more accurately, you can use even smaller drills, but then the process will take longer.
  • Use a chisel and hammer to make a pick out of the drilled contour.

How to drill straight through concrete with a drill bit

First you need to know exactly that the right nozzle is chosen. Always drill at a low rpm. Usually, the tool is in operation for 10 or 12 minutes. During this time it is guaranteed that it will not overheat or accidentally break. If the drill bit of the tool is accidentally left in the wall thickness, it must be carefully removed. No force should be used. The drill bit can break and pieces of it can get stuck in the wall. If necessary, the drill bit can easily be detached from the nozzle.

The drill should be held strictly perpendicular to the surface. If this is not followed, there is a risk of damaging the drill bit and sometimes leaving a dent

It is also important to prevent drilling dust from getting into the eyes. Wear safety glasses for this

You can also use gloves to prevent slipping of the hands during the technological process. Only a person with sufficiently strong arms can drill through the surface qualitatively. Because the process requires considerable effort.

Electromechanical drilling technology

Making holes in the brick with the help of electric tools is much easier than by hand. For this purpose an impact drill or a rotary tool is suitable.

Drilling machine for a brick wall

The drill must meet special conditions, so that you can easily drill through the brick:

  • Only a drill with an impact function should be used. An impact drill has overheat protection so it will last much longer than a conventional drill. It also puts more pressure on the material in which the hole is made.
  • For drilling in brick, a drill with a power of 600 watts or more is suitable.
  • In order to make precise holes of the required depth, it is worth to give preference to a drill with the function of smooth regulation of rotational speed.

A construction drill costs more than an impact drill, but it is much easier to drill with one. A good option is to rent the equipment if you need to make holes larger than 18 cm. In this case a drill with diamond core bits is needed.

It is worth paying special attention to the choice of drill bits. Drills with 6 and 8 mm diameter with pobedite are needed for small holes. This is a tungsten-cobalt alloy that can penetrate tough material without additional sharpening. drills are suitable for making holes with a diameter of not more than 15 mm. Holes with a larger diameter can be drilled using a special nozzle, the drill. It is suitable for holes from 15 to 28 mm in diameter.

The drilling technology for an impact drill or a construction drill is the same:

  • The first thing to take care of is protection while working, because brick or metal chips can get in the eye. A welding mask is suitable as protection. If you do not have one, you can use safety glasses.
  • It is worth marking the spot for the drill hole with a line for the future drilling.
  • Then you can start drilling. The impact drill or rotary tool must be held at a right angle. If the tool is tilted the drill bit will break. The pressure must be gentle, not too much pressure, as you can damage the wall or break the drill bit.
  • Since bricks are dense materials and are not easy to work with, it is necessary to cool the working tool during the work. Dip a little more than half of the drill bit into a bucket of cool water. It must be done carefully so as not to hit the electrical mechanism itself.
  • The drilling process should be continuously monitored. When drilling into a wall there is a possibility that the wire may be caught. Also note that the brick is not homogeneous in structure. If the dust from the drill has become black, the brick section is burned out. In this case, you need to drill at low speed and constantly cool the tool.

To create small holes in masonry electromechanical technology is the most convenient. It is also less energy-consuming than manual drilling.

Preparation Stage

Drilling a brick wall begins with a preparatory phase. Before you make a hole, you need to clearly determine its location. There must not be any wiring or water pipes. For this purpose, a metal detector is used to properly exclude obstacles. But even after that, all work is carried out carefully. On the wall are marked socket lights, as well as switches, from which the electrical wiring extends. For safety work, the initial depth of up to 20 mm is squeezed out with an ordinary screwdriver, a drill is used when there is no risk of damaging communications.

Do You Drill into the Brick or the Mortar?

Using the core to make the marks for the recess. This is how the drill is fixed. The worker must wear safety goggles or face shield, against dust and splinters. The drill must be kept straight, so as not to break the tool and drill through the chamotte brick properly. Periodically turn off the motor to avoid overheating the drill bit. Apply light pressure to the drill to make the depression even. The hole in the wall is made more difficult if the building material is burnt out. Low RPM and impact mode will help make the task easier. The core drill rig is used when drilling a hole with a diameter of more than 30 mm.

With what and how to drill brick walls?

If there is no automatic tool, the brick is drilled manually with the help of a flat borer. Marks are made on the wall with a drill where the hole is to be made afterwards. The dowel is placed at a right angle (90 degrees) to the surface and hammered. After 3 strokes the tool is turned, the hole is cleared of residues and the strokes are repeated until the desired depth is obtained. This is a long and laborious method, after which a lot of debris is left.

Electromechanical

For a hole with a diameter of more than 2 cm it is more effective to use diamond drill bits.

An impact drill or a rotary tool with the same technique is used. Determine the type of hole and its size. On the basis of these data a drill or auger is chosen. It is possible to make a stencil from plywood or other material at hand, to control the distance. It is taped to the wall. Marking is done by using a core. The instrument is held perpendicular to the surface and with a slight push. For diameters larger than 0,2 cm it is better to use diamond core bits on the rotary table.

Automatic

It is a diamond type of drilling, which facilitates labor costs as much as possible, but the use of professional equipment is much more expensive. It is better to have qualification and skills to work with the tool. The maximum depth with this method of drilling is 40 cm. Practically silent at any angle. The hole comes out flat, without damaging the wall and without chipping or cracking. A special nozzle flushes away the dust, so there is virtually no dust or dirt after work.
