The HSS cobalt metal drill bit guarantees a long service life when drilling stainless steel. The long service life is achieved by the 5% cobalt alloy and the fully ground high speed steel (HSS), which provide excellent surface quality and considerable heat and wear resistance. Double fluted and double spiral fluted for rapid chip removal and a longer service life of the drill bit. For alloyed and unalloyed steel up to a tensile strength of 1000 N/mm², stainless steel V2A/V4A, grey cast iron, cast steel, acid-resistant and heat-resistant steels. HSS cobalt metal drill bit, 135 degree rake angle, quadruple point according to DIN 338, diameter tolerance h8. Active cutting and perfect centring without slipping thanks to the cross-ground tip. For alloyed and unalloyed steel up to a tensile strength of 1000 N/mm², stainless steel V2A/V4A, grey cast iron, cast steel, acid-resistant and heat-resistant steels.
