BOSCH Metal drill bit HSS-G DIN 338 12 x 101 x 151 mm 1-pack 2608585940

The ground HSS twist drill drills in metal with maximum precision. The self-centring drill point with cross-grinding and a point angle of 135 degrees enables perfect centring without wandering. The cross-ground drill point eliminates the need for center-punching or pre-drilling up to 10 mm in diameter. This precision-ground HSS steel drill bit drills 40 % faster and requires 50 % less contact pressure than conventionally ground HSS drill bits. It is suitable for drilling holes in alloyed and unalloyed steel, cast steel, cast iron, sintered iron, malleable cast iron, non-ferrous metals and hard plastic. The ground HSS twist drill is manufactured in accordance with DIN 338. It belongs to drill type N (small side chip angle) with a drill point of 135 degrees and diameter tolerance h8.
