2608596822 - HSS-G Metal Drill Bits, DIN 340 6 x 91 x 139 mm

The long HSS metal drill bit, ground, is suitable for drilling deep into metal with the highest precision. Thanks to its increased length, this long drill bit is capable of drilling deep into metal. The ground HSS drill bit with a 135 degree rake angle combines active cutting with perfect centring without slippage, offering the highest precision. The precision-ground and ground HSS metal drill bit also eliminates the need for pre-drilling or pilot drilling up to 10 mm, achieves 40% faster drilling progress and 50% lower thrust force compared to standard-ground HSS drill bits with a conical ground edge. Long HSS metal drill bit, ground, 135 degree rake angle, quadruple ground according to DIN 1412 C, diameter tolerance h8. For alloyed and unalloyed steel up to a tensile strength of 900 N/mm2, forged steel, grey cast iron, sintered iron, malleable cast iron, non-ferrous metals, hard plastics. Cylindrical shank, for use with drill drivers and pillar drills.
