Drill bit set, compact and easy to use
A set of drill bits is a necessary and important item for anyone who works on repairs and actively uses tools. You need to choose the right quality drill bits that will last you a long time.

How to choose drill bits?
- Material suitability - the tool is not interchangeable, so only drill heads suitable for a specific material are used.
- The cutting part - the blades can be of various shapes and diameters, which is necessary for performing fast drilling. Crowned shapes create a large diameter hole, for example, for inserting a lock.
- Diameter - Drill bits can be available in diameters from 1.0 to 55 mm. The size is selected based on the size of the hole to be drilled. When drilling a 10 mm diameter hole, the finished hole will be 11 mm.
- Length - its selection depends on the required depth of the hole. The indicator varies from 3 to 90 cm.
- Type of workpiece - The drill body can be in the form of a cylindrical spiral (for creating holes), conical (for quickly drilling holes of various diameters), and stepped.
- Color - The tool is made of high-speed steel, which is silver in color. This is the cheapest, but shortest-lasting option. The black heads are hardened by steaming, and the cutting edge becomes sharper.
