Bosch Professional Zubehör PRO Metal HSS-G twist drill, 11.9 x 101 x 151 mm

The ground HSS spiral drill bit drills into metal with the highest precision. The self-centering drill tip with a cross-cut and a point angle of 135 degrees allows for perfect centering without wandering. Thanks to the cross-cut drill tip, pre-drilling or center punching is unnecessary for diameters up to 10 mm. This precision-ground HSS steel drill bit 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, and the shank diameter corresponds to the drill diameter. It is used with drill stands and drill drivers. The ground HSS spiral drill bit is manufactured according to DIN 338. It belongs to drill type N with a 135-degree drill tip and a diameter tolerance of h8. Diameter (D) mm: 11.90, working length (L1) mm: 101, total length (L2) mm: 151.
