The ground HSS twist drill bores into metal with the highest precision. The self-centering drill tip with a cross grind and a point angle of 135 degrees allows for perfect centering without wandering. Thanks to the cross-ground drill tip, there is no need for center punching or pre-drilling for diameters up to 10 mm. This precision-ground drill made of HSS steel drills 40% faster and requires 50% less feed force than conventionally ground HSS drills. It is suitable for drilling holes in alloyed and unalloyed steel, cast steel, cast iron, sintered iron, ductile iron, non-ferrous metals, and hard plastics. The ground HSS twist drill is manufactured according to DIN 338. It belongs to drill type N (small side cutting angle) with a drill tip of 135 degrees and a diameter tolerance of h8.
