The ground HSS twist drill drills in metal with highest precision. The self-centering drill tip with cross-bevel and a tip angle of 135 degrees enables perfect centering without wandering. The cross-beveled drill tip eliminates the need for center punching or pre-drilling up to 10 mm in diameter.
This precision ground HSS steel drill drills 40% faster and requires 50% less contact force than conventional ground HSS drills. 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 plastics. The ground HSS twist drill is manufactured according to DIN 338.
It belongs to drill type N (small side chip angle) with drill tip 135 degrees and diameter tolerance h8. The shank is cylindrical (the shank diameter corresponds to the drill diameter). It is used with drill stands and drill screws.,The ground HSS twist drill drills in metal with highest precision.
