Milwaukee step drill bit 6–40.5 mm

Step drills are suitable for drilling the following materials: - ferrous and non-ferrous sheet metals, profiles, and pipes - copper, brass, and aluminum - stainless steel - plastics - Maximum material thickness: 4 mm. - To ensure long service life, we recommend using a coolant. Direct drilling - drilling - deburring - all in one operation. The fast-cutting tip improves centering, reducing slipping and enabling fast drilling without the need for punching or pre-drilling the material. A specially designed tip and step geometry ensure effortless use and reduce the risk of bit jamming at high speeds. Optimized 2-flute sharpened edge geometry enables drilling that is twice as fast and smoother. Special steel and a black oxide coating ensure four times longer service life. Laser-engraved size markings remain visible for a long time. Each step is back-tapered for automatic drilling and deburring. 3 flat secure-grip shanks prevent the step drill from slipping in the chuck and ensure maximum torque transfer.
