Bosch Professional Zubehör PRO Metal HSS-G twist drill, 8.5 x 75 x 117 mm

The ground HSS spiral drill bit drills into metal with the highest precision. The HSS metal drill is ideal for solid work on standard metal tasks. 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 up to 10 mm in diameter. 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 spiral drill bit 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. The shank is cylindrical (the shank diameter corresponds to the drill diameter). It is used with drill stands and drill screws.
