With a tapered chisel edge in accordance with DIN 1689. Tolerances for chip flutes and highly rounded flanks. Designed for metal drilling: precise, clean drilling. And optimized for efficiency to increase drilling speeds. Special surface treatment prevents rust and wear and improves gloss. The flat shank reduces chuck rotation, and the bit shank is marked for easy identification of its size. Due to the tapered reinforcement, this drill has a long lifespan and is less likely to break when you have a specific hole size. At the same time, it can reduce the thrust force by 50%, can accurately machine perfect round holes, and has a longer service life due to the reduced thrust force.By using a fine tip and twist design, precise centering is achieved without the use of a center punch. The drill bit features self-centering to avoid disengagement and remove chips and particles more efficiently. Use this drill to perform pilot drilling on diagonal surfaces. Long-lasting drill bit that prevents slipping and removes debris and particles faster. It has higher fracture stability than ordinary roll-forged drill bits. Compared with ordinary roll-forged drill bits, it has tighter tolerances and a longer service life. High speed steel cobalt drill bit set with hardened and polished blades delivers perfect cuts in hardened steel without wobble and provides excellent long-term performance.
