Bosch 19 Piece HSS-G Drill Bit Set

The Bosch 19 Piece HSS-G Drill Bit Set is a metal drill bit set designed for accurate drilling in steel, cast iron and non-ferrous metals. Each precision-ground HSS (high-speed steel) bit has an exposed 135-degree self-centring split-point tip. This combines active cutting with accurate centring, so the bit doesn't wander at the start of the hole.

The split-point tip removes the need to pre-punch or pilot drill up to 10 mm. Bosch states the ground HSS construction gives up to 40% faster drilling and up to 50% lower feed pressure than standard-ground HSS bits with chisel edges.

This set suits holes in alloyed and non-alloyed steel, cast steel, cast iron, sintered iron, malleable cast iron, non-ferrous metals and hard plastics. The cylindrical shank matches the bit diameter, so the bits fit three-jaw drill chucks, drill drivers and drill stands. The bits are manufactured to DIN 338, Type N (flute angle), with a diameter tolerance of h8.
