●The Silver Star HSS metal drill bits are precision tools according to DIN 338 for excellent dimensional accuracy of the bore.●The steel drill bits are precision ground and correspond to the type N drill bit with a normal spiral, which is specially suitable for alloy and unalloyed steel, cast steel, malleable iron, sintered iron, non-ferrous metals and hard plastics.●Due to the industrial quality, the cylindrical drill bits for steel are standardised and precisely processed.●The right-hand cutting silver twist drill bit has a high-quality surface coating for low friction under the highest load.●In addition, the HSS drill with split point according to DIN 1412 C works up to 40% faster, with 50% less contact pressure, is self-centring thanks to the 135° sharpening angle and causes minimal cutting forces.[8.5]
