With a concrete drill, you can bring the hardest materials to their knees. Thanks to its special drill head, it can do what other types of drill cannot even begin to do with materials like concrete. It is therefore advisable to use it when, for example, a move is imminent. This is because a concrete drill is not only suitable for drilling concrete, it can also be used to conquer the toughest masonry. Nevertheless, there is not just one right choice when it comes to concrete drills, but many different options that should be selected depending on the desired result. Especially if they are not needed for private use. The concrete drills on construction sites can take on completely different dimensions than those you need in your own four walls. With our big concrete drill test 2022 we want to help you find the right drill bit for your purposes. We have compared various products from different manufacturers for you and listed the advantages and disadvantages. This should make your purchase decision as easy as possible. You can also find answers to frequently asked questions here. For a better illustration of some topics, you can also find topic-related videos on this page.




Summary

  • Concrete drills are perfect for working on materials such as concrete, but also natural stone and masonry. They are therefore often the right choice for working on flat walls. Dowel holes are the most common use for concrete drills in private use.
  • Basically, you have to pay attention to what goal you are pursuing: How deep and large should the hole be? Therefore, it is important to find the right size for your purpose.
  • A percussion drill or a hammer drill is best suited for drilling with concrete drills, as they apply more force due to the percussion function. Concrete is a very hard material that is difficult to penetrate. Normal drills reach their limits here.

Guide: Questions you should ask yourself before buying a concrete drill

What is a concrete drill for and what are its advantages and disadvantages?

A concrete drill is a special type of drilling tool and is mainly suitable for working on concrete, but can also be used for working with natural stone or masonry.

Due to its special bit head made of carbide, drilling in concrete and similarly stable materials is easy. Thus, the drill head works like a kind of chisel to loosen the material. This is then removed from the drill hole by the rotary movements. The material discharge of the concrete drill is usually spiral-shaped, similar to other drill bits, and resembles a double helix.

  1. Caution: When using a concrete drill, make sure that they cannot be used as an all-purpose drill.
  2. Material: They are not suitable for drilling into wood, metal or plastic as the holes will be messy and you are more likely to cause damage than make a clean hole.
  3. Problems: If you also drill often, you should make sure that the drill attachment has a long life and does not tend to rust. The quality of the attachment has a considerable influence on working with it. The harder the metal, the more durable a drill bit is.

The most effective way to work with a concrete drill is to use it in a hammer drill. Since concrete and masonry are very strong, the percussion function of the hammer drill provides the power needed to work efficiently. A simple drill is not sufficient for these materials. You should also bear in mind that, depending on the thickness of the material, the hammer drill must also vary in order to be able to apply the necessary impact force.

Advantages
  • Drills through concrete, natural stone and masonry
  • Has a chisel-like drill head
  • In combination with a hammer drill, effective results are achieved
Disadvantages
  • Not suitable for materials such as wood, metal or plastic
  • Life expectancy of drill bits varies greatly
  • Some concrete drills are prone to rust

To give you an idea of how to handle concrete drills properly, we have selected a suitable video for you to illustrate.

How does a concrete drill work?

In order to be able to pierce the material quickly, it is advisable to switch on the impact function. Due to the special shape of the drill head, which resembles a chisel, the material to be worked on is then loosened and then removed from the drill hole by the drill-typical rotary movements of the attachment.

A concrete drill works best when placed on a hammer drill.

To avoid excessive dirt, you can hold a slightly moistened cloth under the hole to collect the discharged construction dirt. Unfortunately, this is not possible for larger jobs, but chiselling tends to produce fine dirt that is easy to remove.

What sizes of concrete drill bits are there and which ones do I need?

As is typical with drill bits, there is a wide range of sizes to choose from depending on the thickness of the material to be worked on and the size of hole required. The sizes vary in length and diameter. The diameters here range from 4 mm to 52 mm and the length goes from 40 mm to 1200 mm in length. Depending on how thick the concrete is or how big you want the holes to be, you have to decide which drill you need. It also makes a difference whether the drill is needed for private or industrial use. If you are still unsure after reading this page, I recommend that you consult an expert. Here we have selected a video for you that deals intensively with the different types of drills and may help you to find out which type of drill you need.

Buying criteria: You can use these factors to compare and evaluate concrete drills

In the following, we would like to show you which criteria you should pay attention to when it comes to choosing the right concrete drill for your purposes and your (possibly) already existing percussion drill.

SDS and drill type

The term SDS refers to the insertion system for drill shanks. A drill shaft is provided with special grooves for better power transmission. Such a shank allows you to change the drill bit without much effort or tools. The drill type is about the right drill bit for the material to be worked on.

Number of pieces

Drill bits can be bought individually or in sets. Here you can see what makes the most sense for you depending on your needs. Most sets consist of five to seven drill bits.

Drill diameter x drill length in mm

Depending on the thickness of the material and the purpose of the hole, you should choose the right size for your project. Here you should pay particular attention to whether the drill is needed for private or industrial use. For example, if a drill has the specifications 4 mm x 85 mm, it has a diameter of 4 mm and a length of 85 mm.

Drill accuracy

Drill accuracy is about how stable the holder is and how high the degree of deflection is when drilling. The decisive factor is the size of the drill core. The larger it is, the lower the deflection and the higher the stability.

Material of the drill and what it is suitable for

What material is the drill made of and does it have a coating? Should it be a carbide or diamond? Titanium coatings, among other things, ensure that the drill bit has a longer life expectancy and are good for drilling hard materials. Cobalt alloys work best for particularly resistant materials.

As diamond is the hardest material in the world, drill bits are often also equipped with it.

This is particularly useful when drilling concrete or similar materials, as working with diamond is much easier. Another advantage of diamond drill bits is the following: due to micro-chipping, the diamond drill bits sharpen themselves and thus form new cutting edges again and again.

Stainless

Some materials, such as iron, tend to rust. Stainless drills are usually of higher quality.

Centre point

Does the drill have a centre point? If so, what is it for? The wood drill has such a centre point. It is used to pierce the material before drilling and thus fixes the drill bit a little.

Incl. sorting box

Is there a sorting box included? If so, do I need it at all?

Lifetime

How many holes can I probably drill with the drill? There are many factors that have an influence here. If the drill gets too hot when drilling for a long time, the tip can anneal. This often happens on larger construction sites. The drill head can also become blunt, which is mainly triggered by using the wrong attachments for a particular material.

Interesting facts about concrete drills

What other types of drill are there?

Besides the concrete drill, there are also the following types of drill: twist drill, wood drill, stone drill, spot weld drill, tile drill, step drill and peeling drill. Depending on the intended use, you have to choose between the different types of drill. For example, a wood drill is not suitable for drilling concrete, while a concrete drill is not suitable for wood. It is very important to choose the right type in order to achieve the best possible result. We have created a small overview for you so that you can compare the different types of drill at a glance.

Drill shapes Suitable for
Twist drills Steel, light metals, plexiglass, plastic
Wood drill bit Wood
Masonry drill bit brick, sand-lime brick, stone
Spot weld drill thin-walled materials
Tile drill tiles, porcelain, ceramics, glass
Step drill clean, step enlargement of drill holes
Peel drill clean, stepless enlargement of drill holes

Which drill do I need for which material?

As already described, it is important to decide which drill is best suited to the material. Depending on whether you want to work on concrete, wood or metal, the drill head, diameter, length and threading of the material outlet will change. The presence of the centre point also varies depending on the material and use. There are drill bits that can be used for different materials. However, to be able to work cleanly, it is advisable to select the drill bit according to the material.

What criteria should be considered when choosing a drill?

When choosing a drill, you should pay attention to the purpose you want to fulfil and the nature of the material. Since you want to learn something about the concrete drill here, we recommend that you focus primarily on the tip of the attachment. This must be made of a resistant carbide plate in order to be able to really work on concrete.

The chisel-like shape of the head is also decisive for a concrete drill. However, there are also models whose head consists of two such chisels. These are longer and intended for rather larger projects.

Can wood or metal drills also be used for concrete?

No, because both are designed to work machinable materials.

The drill can penetrate the material piece by piece, which is not possible with concrete. Here the drill hits a solid surface that is much more stable than wood, for example. The drill would wear out very quickly and no longer be usable. Therefore, you should always make sure to remove the drill bits after use to avoid less than optimal use. https://www.instagram.com/p/BwGFhpCAT14/
