Product descriptions

The Long HSS Twist Drill Bit Ground is for drilling deep holes through metal with maximum precision. Its extended length makes this long bit capable of drilling deeply. The bit's exposed 135-degree self-centring split-point tip combines active cutting and perfect centring without wandering, delivering maximum precision. The split-point tip also eliminates any need to pre-punch or pilot drill for up to 10 mm. This precision-ground bit made of HSS (high-speed steel) enables up to 40% faster drilling rate and up to 50% lower feed pressure than standard-ground HSS drill bits with chisel edges. This bit is designed for drilling deep holes in alloyed and non-alloyed steel, cast steel, cast iron, sintered iron, malleable cast iron, non-ferrous metals and hard plastics. It has a cylindrical shank system (shank equal to drill bit diameter) and is intended for use in drill stands and drill drivers

The Long HSS Twist Drill Bit Ground is manufactured to DIN 340. The drill bit is Type N (flute angle) with a 135-degree tip of 135 and a diameter tolerance of h 8.
