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 drilled element. In this respect, we can distinguish the following types of drills:
- Concrete drill . Many specialists also come across the name "widie". To cope with hard building materials, the drill bit is made of carbide in a monolithic or plate form. In this way, it can easily cope with softer bricks. However, concrete itself requires the use of an additional pneumatic impact drill.

A drill bit for steel and other metals is made primarily of high-speed steel. It is important to keep it sharp, which makes it easier to penetrate metal without generating too much heat. - A wood drill has a pointed tip, resembling a stinger. It allows for axial, precise guidance of the tool in the axis of the hole being made.
- Glass, stoneware or tile drills require intensive cooling. It is easy to cause such an element to crack, so they must have an appropriate structure.
- Universal drills. Theoretically, they work well 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 have to drill something.
To ensure the best results, it is worth investing in professional drills, adapted to the specific application. Thanks to this, the holes will have smooth edges and an aesthetic appearance.
How to recognize the type of drill?
When buying a drill, it is worth paying special attention to the material from which the drill bit is made. It is this edge that is responsible for pulling off subsequent layers of material. For this reason, it is the hardest part of the drill bit. The core itself is often made of more flexible steel to avoid quick breakage of the drill bit when pressing the drill against the material. This is especially visible with very long drill bits, which can bend quite a lot during operation.
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 flutes. In turn, a drill for stoneware and tiles has much smaller flutes and a blade that minimizes the chips that are created.
What material should I choose a drill from?
Choosing the right drill bit material is essential 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. These are suitable for soft materials such as wood, plastics, and soft metals. They are popular for their versatility, but they are not suitable for drilling hard materials.
Another type is carbide drills. They are more durable than steel drills and work well with hard materials such as ceramics, tiles, and reinforced concrete. They are more resistant to wear. HSS (High-Speed Steel) drills are another option. They are suitable for drilling low to medium-hard metals and plastics. They are resistant to high temperatures, making them suitable for working with metals.
In addition to different materials, you need to choose the right shape of drills. In the case of thick reinforced concrete walls, you need to use long drills. On the other hand, a conical drill is designed for thin elements, which smoothly changes its diameter. With its help, you do not have to buy different diameters of tools, because instead of them, only one model is enough. A similar solution is a step drill , which changes its diameter step by step, allowing even drilling of thicker plates and elements.
