HSS-Co5 - DIN 338 - type UNI - point angle 135° - profile ground - cross cut - right-hand cutting - 3-surface shank prevents spinning in the drill chuck - in addition, the shank ensures optimum power transmission - the 135° high performance cutting edge prevents slipping when drilling into curved surfaces - the black chamfer increases wear resistance and prevents cold welding and built-up edges - suitable for non-ferrous metals, structural and carbon steels, high-alloy steels (e.g. V2A/V4A), magnesium alloys, plastics, and aluminium - with straight shank: up to nominal diameter 3.5 mm; with 3-flute shank: from nominal diameter 4 mm. Further technical features: - cutting direction: right-hand cutting - feed in steel up to 1000 N: 0.16 mm/rev - nominal diameter tolerance: h8 - drilling depth: 5xD.
