Milwaukee step drill bit set - 4-12 mm - 4-20 mm - 6-35 mm

Step drill bits 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 go. The fast-cutting tip improves centering for less slipping and enables quick drilling without the need for punching or pre-drilling the material. The specially designed tip and step geometry ensure effortless use and reduce the risk of the bit jamming at high speeds. Optimized 2-flute sharpened edge geometry enables drilling that is twice as fast and smoother. Special steel and black oxide coating provide four times longer service life. Laser-engraved size markings ensure long-lasting visibility. Each step is back-taper relieved for automatic drilling and deburring. 3 flat secure-grip shanks prevent the step drill bit from slipping in the chuck and ensure maximum torque transfer.
