Bosch Professional Zubehör PRO Metal HSS-G twist drill set, 13 pcs.

The ground HSS spiral drill bit drills into metal with the highest precision. The self-centering drill tip with a cross-cut and a tip angle of 135 degrees allows for perfect centering without wandering. Thanks to the cross-cut 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 drill bits. 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 shank is cylindrical (the shank diameter corresponds to the drill diameter). It is used with drill stands and drill screws. The ground HSS spiral drill bit is manufactured according to DIN 338.
