A drill is a must-have for every handyman. It is also useful in every home. On the other hand, it is a basic tool for most professionals. Meanwhile, many people have difficulty choosing the right drill. What are the most commonly used types of drills and what material should they be made of? You will find answers to these and other questions in the article below.

Types of drills
The choice of drill depends primarily on the material being processed. It must be adapted to the hardness and characteristics of the element being drilled. In this respect, the following types of drills can be distinguished:
- Concrete drill bit . Many specialists also use the name "widie". To cope with hard construction materials, the drill blade is made of sintered carbide in monolithic or plate form. This way, it can handle softer bricks without any problems. However, the concrete itself requires the use of an additional drill with a pneumatic hammer.

Drill bits for steel and other metals are made mainly of high-speed steel. You should keep it sharp at all times, making it easier to cut through metal without generating too much heat. - A wood drill bit has a pointed tip, resembling a sting. It allows for axial, accurate guidance of the tool in the axis of the hole being made.
- Drill bits for glass, stoneware and tiles require intensive cooling. It is easy for such an element to break, so they must have an appropriate structure.
- Universal drills. Theoretically, they work for all materials, but at the same time they are not optimized for any of them. Therefore, their service life is much shorter and the comfort of work is incomparably lower. However, they work well for people who occasionally need to drill something.
To ensure the best work results, it is worth choosing professional drills adapted to a specific application. Thanks to this, the holes will have smooth edges and an aesthetic appearance.
How to recognize the type of drills?
When purchasing a drill, it is worth paying special attention to the material from which the drill blade is made. It is this edge that is responsible for removing subsequent layers of material. For this reason, it is the hardest part of the drill. The core itself is often made of more flexible steel to avoid the drill breaking quickly when the drill presses against the material. This is especially visible with very long drills, which can bend quite a lot during work.
The construction of individual types of drills often has characteristic elements. Drilling in wood is often accompanied by large chips, so these types of drills have larger chip grooves. In turn , the drill for stoneware and tiles has much smaller grooves and a blade that minimizes chips.
What material to choose a drill from?
Choosing the right drill material is crucial for successful drilling. There are several types of drill bits you can choose from, depending on the material you plan to drill. The first type is carbon steel drill bits. They are suitable for soft materials such as wood, plastics and soft metals. They are popular for their versatility, but are not suitable for drilling into hard materials.
Another type are sintered carbide drills. They are more durable than steel drills and work well in the case of hard materials such as ceramics, ceramic tiles or reinforced concrete. They are more resistant to wear. HSS (High-Speed Steel) drills are another option. They are suitable for drilling into metals of low or medium hardness and plastics. They are resistant to high temperatures, which makes them suitable for working with metals.
In addition to different materials, the appropriate shape of drills must be selected. In the case of thick reinforced concrete walls, you need to use long drills. However, for thin elements, a conical drill is intended, which changes its diameter smoothly. With its help, you don't have to buy different diameters of tools, because instead you only need one model. A similar solution is a step drill , which changes its diameter step by step, enabling even drilling of thicker boards and elements.
