BOSCH HSS-GStand. line13x101 / 151mm 5 pcs Pack.

This set contains five Bosch HSS-G twist drill bits made from high-speed steel to DIN 338. They are designed for drilling into alloyed and non-alloyed steel, cast iron, non-ferrous metals and hard plastics. Thanks to the self-centring 135-degree split point, you do not need to pre-punch, and work progresses up to 40% faster. The cylindrical shank is compatible with both portable and pillar drills.

Ground high-speed steel drill bit

This twist drill bit is made from high-speed steel (HSS-G) in compliance with DIN 338. The material used helps to drill up to 40% faster while requiring lower feed pressure. The ground flute of the drill bit ensures fast chip removal. The Type N spiral with a standard flute angle and a precise h8 diameter tolerance is ideal for working with alloyed and non-alloyed steel, cast iron or hard plastics.

Precise drilling without pre-punching

The drill bit features a self-centring 135-degree split point that prevents slipping on the material. This eliminates the need for centre punching or pre-drilling holes up to 10mm in diameter. Precise centring ensures accuracy from the very first moment. The cylindrical clamping shank matches the drill bit diameter and is compatible with chucks on both portable and pillar drills.
