Precise centering without center punching and faster drilling on different materials and surfaces such as pipes. The special tip guarantees an easy and smooth drilling process without jamming in the material. This tip also saves time when drilling, as fast and easy drilling is possible without much effort. The twist drill also has the advantage that it is no longer necessary to pre-drill with small drill bits, especially for large drill diameters. This completely eliminates the need to change tools, which also saves a lot of time and tools.
