How To Drill Concrete With A Drill

Choosing a tool and working with it

When choosing a method for drilling concrete, it is worth choosing the right tool. A quality drill with a nozzle will drill the wall quickly and accurately. Not every tool is equally well suited for this purpose. A poor quality concrete drill is time consuming or may not be up to the task.

A quality drill with a nozzle will drill the wall quickly and accurately

When choosing a tool, pay attention to:

• The presence of a speed controller. It is important to be able to adjust the speed for accurate drilling. Working exclusively at maximum speed will result in reaming of a large hole and surface damage;
• Possibility to set the hammer drill mode. Useful for punching through thicker layers;
• Drill depth adjustment;
• Auxiliary handle included. A professional and powerful drill belongs to heavy power tools, it is better to have a built-in handle for two-handed operation;
• Satisfactory power indicators, so that it is convenient to drill concrete, brick and other materials, because the drill is a universal tool.

Before starting work, it is better to get used to using the selected tool. It should be comfortable to use with one hand or two. One hand rests on the handle and the other on the detachable handle or side of the case.

Any device of an electric type is vulnerable to temperature changes, it is recommended to wait until it warms up or cools down to room temperature before turning it on. With sudden changes there is a risk of condensation. If there is temporarily no need for drilling, it is better to disconnect the power tool from the mains.

Power selection for drills

When drilling concrete, it is best to use a device with a power of 600 W and 2500 rpm. For a more accurate selection of the rotation speed, you should familiarize yourself with the recommendations of the drill manufacturer. A crumbling method is used for drilling concrete, which does not require high revolutions.

Drill selection

If at the stage of drilling concrete with a drill, the process stalled, holes are drilled with a hammer drill or the impact mode is turned on. The only drawback of the rotary hammer is large holes, diameter from 13 mm. Tight areas can be easily broken with a mechanical punch with a hammer. The area should be pierced until the material softens. Then continue drilling the hole.

To drill several holes in concrete, special solders are used on the nozzle:

• Victory tip;
• Universal drills, but should be cooled regularly;
• Diamond drills for concrete are relatively expensive material, but durable.

When drilling, make sure that there is no abnormal sound of touching metal. If it hits the armature in the wall, it is important to complete the procedure while the nozzle is still sharp.

Choosing a drill for a drill

You can properly drill concrete with reinforcement in 3 stages:

• Reach the metal layer with a victorious tip.
• Install a drill bit for metal. the reinforcement is soft and should be easily drilled.
• Continue working with a concrete drill.

A little about the drill device and drill installation

A standard drill includes:

• Mains cable;
• Power button;
• Capacitor wires;
• Reversible system;
• Brushes with springs;
• Anchor;
• Stator;
• Reducer with chuck;
• Bearings;
• Keys;
• Screws.

Impact drill device

Correct installation of the drill increases the quality and safety of work. If the bit is loosely tightened, there is a risk of the drill sticking out and injury. It is recommended to immerse the tip as far as it will go and clamp it with a special wrench.

Before drilling concrete with a drill, it is recommended to check that the drill is fastened in the center along the axis. If the slightest displacement occurs, the hole will be too wide, there is a risk of rod breakage or sticking out of the chuck.

Before starting work, check for dirt on the drill. It is best to use a rag to clean the drills. The easiest way to drill through concrete is to press firmly on the handle once.

How to properly drill concrete with a drill?

Concrete walls are the backbone of many high and low-rise buildings. Sooner or later, each tenant has to hang or attach something to the wall. A drill for concrete comes in handy for attaching sconces, lamps, paintings, equipment, equipment, mirrors, etc. When using a conventional drill, it overheats, smoke appears and after a few holes you have to change the nozzle. Proper drilling will help you complete the procedure quickly, and the tool will last for many cycles of use.

Drill Errors

The workers’ comments helped to identify the actions to be undone during the drilling process:

• Do not hold on to the rotating chuck during operation. There is a body or handle for safe holding;
• If you work with gloves, you should use the tight varieties. The protruding ends of the gloves can twist during rotation;
• Pressing down on the drill with all your might is not the best solution, as the builder loses balance and may fall. Another problem with excessive force is drill breakage;
• It is important to avoid getting a person’s hands on the back of the concrete, otherwise the drill will go through the wall and cause serious injury.

Drilling metal

Metal

To properly drill metal, you need to know the properties of this material. It is very hard, difficult to mechanical stress and requires drills of a certain strength. If the drills are bad, the job will not work. It is not recommended to save on the tool, because a poor, low-quality tool can destroy the material.

Drilling thin metal sheets is a real pain for most craftsmen. The steel tends to break free, which can result in serious injury. To prevent this from happening, the steel sheets must first be fixed. To do this, you can make a special device that will clamp steel.

When cutting a blind thread, various debris often gets into the hole. To eliminate this phenomenon, you need to pour a little paraffin or wax inside.

Drilling concrete

Concrete wall

Drill bits with victorious tips Holes in concrete can be needed for a wide variety of purposes. The need for them may arise during normal repairs. For example, holes in a concrete wall are required when installing a toilet and other plumbing, for installing shelves and sliding doors. There are tons of examples when you need to use a drill to work with this material. Concrete has its own special properties, therefore, work with it is also carried out according to certain rules.

How to drill concrete? For this purpose, you need to purchase drills with victorious tips.

It must be remembered that the drill is used in working with concrete only for drilling small holes (up to 12-13 mm). If you need to make a larger hole, it is better to use a puncher.

Drill breakage and jamming are the most common problems when drilling concrete. Drills can also become clogged, so they must be cleaned and sharpened regularly.

Drilling is done as follows:

• First, the point at which the hole will be made is outlined.
• Then you need to make a small depression at this point with a conventional drill.
• Is the deepening ready? So, it’s time to change the conventional drill to an asymmetric one. It will allow you to work more efficiently.
• If the hole is made for a dowel, then it must exceed its size. Because concrete dust will significantly reduce the headroom.
• It is better if the drill used in the work has a built-in level. Anyone who has drilled concrete before knows how difficult it is to keep the tool in a uniform position at all times. Especially if the work is long.
• During operation, the drills can be regularly moistened with plain water. This makes the process easier.

How to drill correctly

• 1 Drilling metal
• 2 Drilling tiles
• 3 Drilling in concrete
• 4 Drilling wood

In this article, we will tell you how to properly drill various materials with a drill: metal, tiles, concrete, glass, wood. Working with wood, metal, concrete and tiles has its own subtleties. If you follow some principles, then the holes will be smooth and of high quality.

Drilling tiles

Drill selection

Tile is a very fragile material. Wrong move. and it might just split. To properly drill a tile, you need to follow simple rules. First of all, it is necessary to select special drills that are soldered from carbide. This will reduce the load on the work surface and facilitate the drilling process.

The point where it is necessary to make a hole must be marked in advance. This is done with a tap or marker. This point will ensure that the drill does not slip. The mark is made on the outside of the tile.

We drill tiles

Sometimes it is necessary to drill a tile that is already glued to the surface. In this case, glass drills can be used. There are no special secrets when drilling tiles. The main thing is not to exert too much effort, otherwise the tile will crack. The better the drill, the easier the work process is.

Drilling wood

Wood

Wood is a soft natural material that lends itself well to mechanical stress. However, a number of rules must be followed when working with wood.

• When punching holes in the logs, it is better to fix the material. Because otherwise the master risks losing the drill.
• If you need to make holes in small pieces of wood, then you can put regular emery under them. Then the details won’t slip.
• Burrs after drilling can be removed by wrapping felt around the drill.
• Wood has many varieties, and each of these varieties contains its own characteristics. For example, plywood almost does not lend itself to conventional drilling, it can easily crack. To prevent this from happening, it is necessary to use not ordinary drilling, but a tool that looks like a potato peeler. If you sharpen a steel pipe, you can use it to make many great holes in plywood.

When working with wood, it is often not the drills that suffer, but the wood itself. You should not press too hard on the material, some types of boards may split or crack from this. This is especially important when making large holes. Drills for wood are suitable from among inexpensive.

How to drill a concrete wall. a possible way out of the situation

Sooner or later, most people living in houses with concrete walls need to hang a cabinet, lamp, shelf or painting. At this point, the pressing question arises of how to drill a concrete wall. It’s no secret that every home craftsman at least once in his life faced this problem, but not everyone knows how to solve it. Many courageously torture the drill and their own strength, but without achieving the desired result, they abandon everything until the next attempt to make a hole in the wall. But the drill eventually breaks, and the shelves remain standing somewhere in the corner of the room or gathering dust in the closet. But there are still options. you just need to know them and be able to use them.

What the professionals advise?

Concrete structures are strong enough and difficult to drill. In addition, drills quite often come across rubble, which is part of the concrete mixture, from which wall and ceiling slabs are formed.

Holes in concrete have to be made quite often, especially in the process:

• Finishing works;
• Furniture installations;
• Air conditioner suspension;
• Additional electrical wiring device;
• Plumbing installation.

There are two ways to solve the problem of holes in a concrete wall:

• An impact drill, or better with a hammer drill, with a victorious drill;
• Diamond drilling.

How to choose a tool?

For a larger volume of work, a hammer drill or drill with an impact function and drills with victorious tips are needed. An impact drill combines a rotary motion with a reciprocating motion, which helps it perfectly copes with light concrete, and when asked how to drill a concrete wall, which is a load-bearing one, there is a simple answer. a perforator will become the best assistant, the main purpose of which is to punch concrete fences. There is one more difference:

• The hammer drill is designed for drilling holes no more than 12 mm in diameter;
• The hammer drill is capable of drilling large holes.

The reinforcement found in the body of the concrete wall should be drilled with metal drills.

What will help the home master?

In domestic conditions, when it is necessary to make 2-3 holes in concrete, you can do with an ordinary drill, without the impact function. To do this, it is necessary, as the victorious drill is immersed in the body of the wall, from time to time to break the concrete with a strong metal pin (punch) that matches the size of the hole diameter. It is used when the drill starts to "get stuck" in the wall. At this moment, a steel punch is inserted into the hole and they begin to hit it with a hammer or a sledgehammer, trying to crush too dense areas and punch the hole deeper. In this case, the pin is slightly turned. Then the hammer drill can again come into operation.

All of the above steps are repeated one after another until the hole is increased to the required depth. This method is quite laborious and tedious, but quite acceptable for a pair of holes.

Alternatively, when drilling a hole in concrete, you can use universal diamond-coated drills. They are highly effective when working with metal, gravel and concrete. They can be installed only on a conventional electric drill, or on a tool with the vibration function disabled.

Than big holes are drilled?

Professionals who are constantly faced with the problem of drilling holes in concrete use special equipment, which includes:

• Powerful electric motor;
• Drilling drive;
• Diamond drill bits of different diameters;
• Base-mounted rail.

Diamond drilling allows you to make holes of large diameter. up to 40 cm. The process is fast enough, efficient, without unnecessary dust and noise. Water is automatically supplied to the drilling site, which simultaneously cools the diamond core bit and flushes away dust.

With diamond drilling, the holes are precise in shape and clear in outline, with a polished inner surface. They can be made in various enclosing structures at any angle to the horizon, and the possibility of cracks or chips in the concrete is completely excluded. Destruction occurs only at the location of the future hole.

Specialized firms are engaged in diamond drilling, so if you need to drill holes in concrete of large diameters, you can invite craftsmen with their own equipment. And it is not necessary to buy a diamond drilling machine specially for this.

Choosing a tool and working with it

When choosing a tool to drill a hole, you should understand that your work depends on it. A good drill accurately drills a concrete wall or other necessary material, simplifies the drilling process, while a bad one will take a lot of time, may not cope with the task, or complicate it. What you need to pay attention to when choosing a drill:

• Is it possible to change the drilling speed? this point is important, since the correction of the speed mode will ensure the accurate operation of the drill, helping it not to damage the surface.
• Are hammer drilling and depth adjustments possible? hammer drilling can be applied to problem areas, softening them.
• Is it possible to hold the drill with both hands? the drill is not an easy tool and therefore models that are equipped with handles should be preferred.
• Is the power of the tool sufficient for your job??

Having decided on a drill, you need to get the hang of it before starting work. To do this, take the drill in one hand, like a pistol, place the other hand on the tool handle (if it is not intended by the design, the hand is placed near the cartridge). It is necessary to hold the drill in your hands strictly horizontally so that the hole does not work out with distortions and at the wrong angle. Wait until it reaches the ambient temperature before turning on the drill. Sudden temperature changes can provoke condensation. If during work you decide to take a break. disconnect the tool from the mains.

Drill selection

This point can rightfully be considered the main one, since the quality of work and the safety of the drill itself, as well as the accuracy of the work, depend on a properly selected drill. Today there is a huge variety of different drills on the market: for working on wood, metal, concrete. The latter are distinguished by a triangular tip. For a concrete surface, it is best to use a carbide drill, for example, a victory drill. This type of drill crushes the material without tearing it, which is ideal for concrete floors.

If in the process of drilling the wall the drill does not go forward, encountering a dense area, it is recommended to use a punch. After inserting a punch into the hole, it is hit with a hammer until it starts to move forward and softens the problem area. Then you can continue drilling.

It should be noted that without a punch, a perforator can easily cope with this kind of difficulty, but holes are made with it that exceed 13 mm in diameter. If you want to use universal drills when drilling, you need to remember that they require cooling, vibration off and are only suitable for a conventional drill.

How to drill concrete with a drill?

Each of us has repeatedly faced the need to mount various objects on the walls that add variety to the interior, create coziness, or simply remind us of the pleasant moments of life. Most often, you have to fix lamps and sconces, paintings and photographs, mirrors and shelves to a concrete surface, install an air conditioner, or a TV. If, in the case of a small painting, or a photograph, you can do with driving a nail into the wall, then when the question is about more massive and heavy objects, the question of drilling holes arises. In order to avoid misunderstandings when working with concrete, for example, breakage of a drill, dullness of it, it is worthwhile to competently prepare a partition, choose a quality tool and choose the right drill.

Power selection for drills

The optimal power for working on concrete, in order to drill a hole, is considered to be a power of at least 600 W and 2500 rpm, but this figure must be adjusted depending on the manufacturer’s recommendations so as not to spoil the drill. As already mentioned, concrete "crumbles" when we drill, and this does not require too much speed.

Surface preparation

Before you start drilling, you need to make sure that there are no wiring, pipes, electrical cables in the selected overlap location. A metal detector will help to cope with this task, as it reacts to non-ferrous metals, iron and steel.

If you ignore this condition, you can stumble upon fittings, damage the drill, or cables / pipes that were hidden in the ceiling. If this section satisfies all of the above requirements, then a point is marked on the wall, and after that a small depression is made in it at a slow speed using a drill. It is also worth remembering that the surface of a concrete wall is looser than subsequent layers.

A little about the drill device and drill installation

The classic drill consists of a power cable, a button, a capacitor wire, a reverse, brushes and springs, an armature, a stator, a gearbox and a chuck, bearings, a key and fastening screws. Correctly inserted drill improves the quality of drilling, and is able to secure it.

The first thing to check when starting to work with the drill is whether there is any dirt on the drill itself. When cleaning drills, a rag will be an excellent assistant. If the drill is loosely fixed, there is a risk that it will fly out and injure the master. Accordingly, it is necessary to immerse the drill as much as possible into the chuck (all the way!).

It is important to ensure that the drill in the tool is fixed strictly along the axis. If this rule is not followed, drilling in concrete will be of poor quality, the shape of the hole may be unpredictable, and the cause of all these misunderstandings will be the elementary beating effect of the drill.

How to drill correctly?

In order to quickly and efficiently drill a concrete wall, you should adhere to certain recommendations.

• Preparation stage. Before you start working, you need to make 100% sure that you have drills for various purposes with you. A situation may well arise when the master suddenly stumbles upon a metal obstacle in the wall. Then you will need to change the concrete drill to a metal cutter, make a small hole in this material and then calmly continue drilling with a concrete nozzle.
• Break. If you work with a heavy hammer drill or a home drill in a continuous mode, you will need to take short breaks in work, this is necessary for the drill to cool down for a couple of minutes. Continuous rotation can cause the product to become seriously hot, which reduces its strength and may result in breakage. The drill cooling process should be natural, that is, without the use of cold water or other coolants.
• Working hours. If you need to drill through concrete with a drill, you need to turn on the special hammer mode. This can be done by simply turning a certain lever on the drill body.
• Drilling a ceramic surface. For high-quality drilling of such a fragile material, concrete drills are often chosen. In order for the ceramics not to split in the end, you need to work not with a simple puncher, but with a professional drill without a shock mode.

Drills for concrete for a drill: structural features and application

• Features of the structure of the drill
• Which to choose?
• Surface preparation
• How to drill correctly?
• Professional advice

One of the most common misconceptions among non-professional craftsmen is the fact that, in their opinion, surfaces made of a material such as concrete can be easily drilled with the most ordinary cutters for metal or even wood. They seriously believe that the same drill can be easily applied to any surface.

Features of the structure of the drill

A drill is a type of cutting tool designed for drilling various holes. A concrete drill is a special tool required for drilling bricks, fully cured concrete and any of its derivatives, as well as stone and stone-like materials. Drills for concrete differ from other types by special soldering over their entire surface, it is they who allow the drill to become as strong as possible. They also allow him to retain all his quality characteristics much longer.

• The tips of products for drilling concrete have a slightly blunt end and a fairly strong soldering from Pobedit.
• Cutters for concrete work most often have a specific whitish color, drills for metal coatings are distinguished by a black color, for wood. a light.
• The tip, when compared to the rod, will be slightly larger.

A concrete mill consists of the following parts and is made of the following materials:

• Body (core). most often made of high speed steel;
• Cutting element. it is produced from carbide steel;
• Tungsten and Cobalt (VK);
• Titanium and tungsten, as well as cobalt (TC);
• Titanium and tantalum, as well as tungsten and cobalt (TTK).
• Carbide. It combines the body and the carbide itself.

Surface preparation

If you need to quickly make a deep hole in the wall, you should first make sure that there is no wiring in the place where you will start drilling, there are no built-in pipes (for example, heating) or an electric cable. The easiest way to quickly find such elements in the walls is to use a conventional metal detector (call a specialist with this device at home). There are almost always fittings in the walls of residential buildings, so you will need to install the device to search for non-ferrous metals (wiring), and then to steel. If you do not take into account this condition, you run the risk of stumbling upon the reinforcement when drilling, and then the drill from the win will be damaged.

Before starting drilling, a point is put on the wall. To prevent the tool from sliding, a small depression is made with any durable metal object or the drill itself at low speeds. After this procedure, the drill will easily enter the wall. It should be borne in mind that a facing material is usually installed on top of the cement, it is much softer than the walls themselves, and therefore at first the drill will go easily, and then suddenly it will rest against a harder material.

Which to choose?

It all depends on the type of device with which you will use the existing drills.

• Cutters for conventional drills. The shank will be in the form of a simple cylinder or polyhedron. The drills are suitable for working with bricks or foam blocks. A drill with high power is selected for the drilling process.
• Rotary hammer cutters usually have more solid dimensions. You will definitely find the SDS max mark on the drill body. Such products are needed for drilling the most durable surfaces. reinforced concrete, for example.

You may not be able to drill a wall of concrete with an ordinary home drill. If you are not able to do this, just take another tool, for example, a hammer drill, because it has significant power and excellent impact force in any drilling. The hammer drill is often referred to as a concrete drill by many craftsmen. There are 3 types of this popular tool:

• Auger. used to create the deepest and widest holes without any problems;
• Spiral. ideal for medium sized holes;
• Shallow. used to get small holes.

Qualitative use of this kind of drills for an impact drill or a professional hammer drill will require their firm fixation in the device. To simplify this task, the device itself has a certain thickening at the very end.

Crown product can be of two types.

• Diamond. The drill is similar to a tube or bit, which is fixed on the rod, and has diamond dusting along the edges.
• Pobeditovoe. The attachment is very similar to the one described above. The difference is that there is no sputtering, it is replaced by small victorious teeth.

When choosing a good drill for working on concrete, you should carefully examine it from all sides.

• The product must be free from defects, scratches, chips or bruises.
• The color of the product should be uniform, and by this criterion you can determine the quality of the finishing. For example, steel color will mean that such processing has not been performed at all, black color will indicate that the product has been hardened with superheated steam. The yellow tone will indicate the excellent quality of the product, since it has clearly undergone a special treatment to reduce the stress of steel. But it is still better to purchase drills that are carefully covered with the thinnest layer of protection made of titanium nitride, then they will have a golden color.
• A large assortment of drills is represented by both foreign trade marks and our companies, their price will directly depend on the "promotion" of a particular brand. The difference in cost between products for a single use and a tool for professionals is quite significant, this applies to both the quality of the product and its characteristics.

• It is not very profitable to purchase ready-made kits, it is best to choose 1 good drill with suitable parameters. The cost will depend on the diameter, but not significantly. Sometimes a 0.8 cm rod that has undergone high-quality processing will cost more than a 1.2 cm punch drill bit, but from a Chinese company.
• Among the best foreign manufacturers, the brands Bosh and Metabo, as well as Stayer and Makita, are most often distinguished. Their cutters are well known for their increased reliability and long service life. Among our manufacturers, the products of the Zubr, Enkor and Interskol trademarks have proven themselves in the best way.

Professional advice

• If the drill is a little dull when drilling, then to return it to working condition, you can take an angle grinder and sharpen the device. You can avoid this situation if you prepare your tool more carefully for full-fledged work.
• To drill concrete, you need to have with you the usual drills, with which you can quickly penetrate into the depth of many materials, and a couple of nozzles in case a significant obstacle appears in the path of the drill.

For information on which drill to drill in concrete, brick, stone, bathroom tiles, glass, wood, drywall or foam concrete, see the following.
