Bosch Professional Zubehör Twist drill

The ground HSS spiral drill bit drills into metal with the highest precision. The HSS metal drill is suitable for solid work on standard tasks involving metal. The self-centering drill tip with a cross-ground design and a point angle of 135 degrees allows for perfect centering without wandering. Thanks to the cross-ground 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 spiral drill bit is manufactured according to DIN 338. It belongs to drill type N (small side cutting angle) with a 135-degree drill tip and diameter tolerance h8. The shank is cylindrical, with the shank diameter corresponding to the drill diameter. It is used with drill stands and drill screws.
