The ground HSS twist drill drills in metal with the highest 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 centre punching or pre-drilling up to 10 mm 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 alloy and non-alloy 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 rake angle) with drill point 135 degrees and diameter tolerance h8.
