7-piece Metal Drill Bit Set Mini-X-Line HSS-G, 135°, 2 mm - 10 mm. Ground drill bit with high precision for solid work on standard metal tasks. Self-centering drill tip, cross-ground, with a point angle of 135 degrees and an active drilling approach allow for perfect centering. Made of HSS steel for fast operation. No center punching or pre-drilling is required for diameters up to 10 mm. Diameters: Ø 2 / 3 / 4 / 5 / 6 / 8 / 10 mm. The shank is cylindrical (the shank diameter corresponds to the drill bit diameter) and is used with drill stands and drill screws. The ground HSS twist drill bores into metal with the highest precision. The self-centering drill tip with cross-ground and a point angle of 135 degrees enables perfect centering without wandering. Thanks to the cross-ground drill tip, center punching or pre-drilling is unnecessary for diameters up to 10 mm. This precision-ground HSS drill bit drills 40% faster and requires 50% less feed pressure 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 ground HSS twist drill is manufactured according to DIN 338 and belongs to drill type N (small side cutting angle) with a 135-degree drill tip and a diameter tolerance of h8.
