The drill bits are made from precision-ground high-speed steel (HSS-G) in accordance with the DIN 338 standard. Thanks to the 135° self-centring split point, you can start drilling precisely without the need for prior centre-punching. The drill bits are ideal for working with alloy and non-alloy steel, cast iron, and hard plastics.

Precision-ground HSS-G drill bit

Bosch spiral drill bits are made of high-speed steel (HSS-G) and comply with the DIN 338 standard. The precision-ground HSS-G drill bit has a type N flute for efficient chip removal while working. The drill bit's geometry contributes to up to 40% faster drilling progress and requires up to 50% less feed pressure.

Easy and precise drilling

The drill bits have a 135° self-centring point that prevents slipping on smooth surfaces. Thanks to the split point, there's no need to pre-drill holes or use a centre punch for diameters up to 10mm. The drill bits are suitable for working with alloy and non-alloy steel, cast steel, cast iron, sintered iron, malleable cast iron, non-ferrous metals and hard plastics. They are secured in the drill chuck via a cylindrical shank.
