What Does A Concrete Drill Look Like For A Drill

Drill types and parameters distinctive features

When choosing a drill for concrete, builders ask how to distinguish its performance and make the right choice. Each product is different in size, produced in a given diameter and length. One of the small drills for concrete work 4-5 mm, it is no longer possible to drill a thinner hole of this diameter, its depth will be about 5 cm.

For example, with a diameter of 12 mm or more, the drill will be 1000 mm long, this will be enough to make a through hole in all walls except the bunker. The largest diameter is about 30 mm, it is not easy for them to work, there is a heavy load on the hammer drill, it takes a lot of time for it to cool.

If it is necessary to make a larger hole, a core drill is used, which has a centering drill and a crown around it. Thanks to this, the process is fast enough, and the load on the rock drill is small.

The core drill is coated with diamond plating or Pobedit lining. A drill with a victorious tip is set for drilling and impact mode, with a diamond one for drilling.

Diameter selection

The drill diameter is chosen taking into account the fact that when working with dense material, such as concrete, beating occurs during operation. As a result, the hole comes out slightly larger than planned. For this reason, the diameter must be taken slightly smaller than the planned hole itself. The length of the element indicates the greatest depth that the hole should be.

Drill design

The drill design is quite standard. It consists of standard accessories such as shank, cutting elements and chip evacuation elements. Made of high-hardness alloys, the tip resembles the letter T.

These tips are used when working with hard materials (metals, concrete, marble). To avoid confusion, it is better to see a photo of a drill for concrete.

Some of the best concrete drills are victorious. This special alloy of tungsten and cobalt will win, but for a long time this alloy has ceased to be used due to its high cost and cheaper and higher quality analogues have come to its place.

The victorious drill is presented on the market in very large quantities, but the brand is not indicated on the explication of the drill itself, which means an independent selection based on your experience or the knowledge of the seller.

If you see drills with incomprehensible Chinese symbols, it is better to bypass this purchase, since they will be enough for a couple of minutes of work (at best).

There is one tradition, the essence of which is to wet the tip of the drill (or all of it) with water. Some argue that doing this will save the drill and help it work better without breakage. But as the researchers found in production, the cooling of the drill does not affect its performance in any way.

Also, a victorious drill can be sharpened quite easily, but this must be done carefully, there is a risk of overheating the drill too much and breaking off part of it. This should be done when blunting the drill.

Drilling recommendations

If stones hit during operation, it is difficult for this element to move on, the stone must be broken with a bump stop, then continue working. When drilling a hole in a load-bearing wall or in a ceiling, it is recommended to use a perforator, with its help the work can be done as quickly and efficiently as possible.

It is also better to drill a reinforced concrete wall with a hammer drill. For a hole in the ceramic on the wall, you cannot use the impact method and use a drill for concrete, otherwise the tile will collapse.

Drilling with a drill

For small work, especially in an apartment with thin walls, you can make a hole with a drill designed for drills for working with concrete. It can be either a win or a diamond piece. A drill with a cylindrical shank is used for an impact drill. When working, it is recommended to select a medium speed.

Which concrete drills for a drill are better to choose depends on the type of drill.

Most popular brands

The best concrete drills for drills from foreign manufacturers:

  • Makita;
  • Bosch;
  • Metabo;
  • Stayer;
  • Fit.

Products are considered to be of high quality, therefore they have a high cost, especially Bosch products, which have a four-spiral design.

Domestic manufacturers:

  • Interskol;
  • Bison;
  • Anchor;
  • Hurricane.

The drills have an average price category, and, accordingly, a short service life. Products from a Chinese manufacturer can also be of good quality, but only if they belong to the corresponding price range. During the construction of buildings and other cities of Russia, workers often use the listed brands of products.

If stones hit during operation, it is difficult for this element to move on, the stone must be broken with a bump stop, then continue working. When drilling a hole in a wall of a supporting type or in a ceiling, it is recommended to use a perforator, with its help the work can be done as quickly and efficiently as possible.

The length of the element indicates the greatest depth that the hole should be.

Drilling with a hammer drill

The hammer drill is the most powerful tool, suitable for large volumes of work and for drilling concrete walls.

The Pobedit tip is resistant to heavy loads. When there is a hole at the edge of the structure, it is not recommended to drill concrete with the percussion method, because chipping of the concrete structure may occur, and when working with ceramic tiles, the material will simply split.

In this case, it is better to use a diamond drill for concrete for a perforator, it has a higher hardness than a victorious one, during work it is necessary to take breaks to cool it down, drilling at high speeds is prohibited.

Drills from victorious

Win as the alloy was developed in 1929, the main composition is cobalt and tungsten, where 10% cobalt and 90% tungsten. They effectively cope with bricks, cinder blocks, concrete. It is possible to crush and cut concrete with a drill, it can withstand impact loads quite well, and no deformation of its cutting edges is observed. Steel products are deformed and do not work as efficiently.

One of the advantages of the work is that there is no need to apply excessive force on the drill from Pobedit.

How to properly drill walls: expert recommendations

The efficiency of drilling work depends not only on the quality of the tool used, but also on adherence to the recommendations for performing the workflow:

  1. Be prepared for the unexpected. Choosing a drill bit for concrete of the appropriate diameter is only half the battle. This is especially true when it becomes necessary to drill concrete with reinforcement. Many craftsmen can break several drills or drills without understanding what the matter is. When drilling such walls and ceilings, steel reinforcement can be caught, which is absolutely natural. Only a metal product can handle fittings. Having reached the reinforcement, you should put a drill for metal in the drill, pass the reinforcement, and then continue drilling again. It is also worth remembering that carbide solders must be sharpened, but this requires purchasing a special diamond disc.
  2. Avoid overheating. When drilling holes in the wall, the working part of the product heats up, which negatively affects its design parameters. If you don’t let the tip cool down every 15 seconds, then the metal it consists of will simply start to melt. Every 15 seconds of operation must be followed by a pause of 10-20 seconds.
  3. If in the structure of concrete during drilling comes across a stone that cannot be drilled, then you need to use a hammer drill to crush it. It is quite difficult to crush stones, therefore attempts can only blunt the cutting edges of the devices used.
  4. A more powerful hammer drill is recommended for drilling holes in a solid concrete wall. If the wall is made of strong concrete, then it will be very difficult and time-consuming to drill it with an impact drill, and possibly unrealistic. The drill structurally has less impact force and it is not always enough for strong material.
  5. The hammer mode is contraindicated for drilling in ceramic materials. This immediately leads to the destruction of the product, therefore drilling without impact should be used.

In conclusion, it should be noted that when choosing drills for concrete, we recommend giving preference to well-known brands and manufacturers. This ensures the quality that the drill will do the job. The use of nameless devices only indicates that it is a cheap fake, which often does not allow achieving the desired result.

Popular brands of concrete drilling tools

The construction market offers a wide range of high-quality, reliable, professional tools that will satisfy any needs of both DIYers and large developers. There are low-power, medium-power and high-power drills that can be used not only for drilling concrete, but also for other materials such as wood, metal, tiles, stone, etc. Some of them are equipped with additional functions, for example, the drill can work as a mixer or screwdriver.

Popular foreign brands that deserve attention:

  • Makita.
  • Bosch.
  • Metabo.
  • Dewalt.
  • HITACHI.
  • SPARKY.
  • Interskol.
  • Bison.

Drill bit parameters for concrete drill

For drilling large holes, long drills with a large diameter are usually used, since thin and narrow ones may not withstand and break under high stress. The most common diameters: 4, 5, 6, 8, 10, 12 mm, there are also larger parameters, it all depends on the required depth and width of the future recess. Drill length for concrete, respectively, is: 50, 100, 150, 250, 540 and maximum 1000 mm.

On the subject: What kind of drill to drill concrete. We drill different materials with different drills. Device design

What a concrete drill looks like is known to every master who at least once had to drill a hole in the wall of his house. Their distinctive feature is the presence of special soldering from durable alloys. The hardness of such solders is very high, which allows drilling holes in strong types of materials.

Most drills for concrete are coated with victorious surfacing (sometimes diamond spraying is used), or more precisely, soldering is applied only to the head of the product. In our time, it is customary to call an alloy of tungsten and cobalt the winner. Victory drills are the most durable products for use on brick, plaster and concrete surfaces. Structurally, the considered device has the following form, as shown in the diagram below.

It is the cutting edges that play an important role, which are actually made of carbide metals.

Types and parameters

Drilling holes in concrete with a drill is carried out directly using special drills. In addition, first you need to decide what kind of tool will be used as a working tool. Note that drill bits are divided into three main types:

  • Cylindrical shank.
  • With a hex shank.
  • Diamond.

Cylindrical shanks are among the most common. These shank options are suitable for both key types of chucks and keyless.

When choosing a drill, you need to pay attention to its diameter. When working with such drills, beating occurs during the drilling process, which contributes to the automatic expansion of the hole. This indicates that if you need to drill a hole for a 6 mm dowel, then it is recommended to use a drill with a diameter of 5 mm. The length of the tool allows you to determine the depth of the hole. There is a standard table of correspondences of drill diameters and their lengths.

Winning drills are characterized not only by diameters, lengths and workmanship, but also by manufacturers. The following brands are generally recognized as the highest quality manufacturers: Bosch, Metabo, Makita, Bison, DEWOLT.

Diamond drill bits are used to work with brick, concrete, plaster, ceramics and reinforced concrete. Diamond products can even be used for drilling metal surfaces. When choosing before buying, you need to pay attention to the cost. A good product will never cost too much.

About concrete drills for drills

If it is necessary to drill holes in the wall, they resort to using drills for drilling in concrete. The use of drills for metal for such purposes is irrational, since the product almost does not cope with its task, while their cutting edges quickly become blunt. Concrete tools are equipped with special tips, thanks to which fast and efficient drilling of holes is carried out.
