Precise drilling with HSS-G steel

The drill bit is made of high-speed steel (HSS-G) in accordance with the DIN 338 standard. The steel undergoes precision grinding, which contributes to a fast work rate. Its self-centring 135-degree split point tip actively prevents slipping on the material, so you can start drilling without prior centre punching. The diameter accuracy corresponds to the h8 tolerance. The drill bit is equipped with a cylindrical shank.

High performance and wide application

The self-centring 135-degree split point tip speeds up the drilling process by up to 40% and reduces the required feed pressure by up to 50%. The drill bit is suitable for drilling holes in alloyed and non-alloyed steel, cast steel, grey cast iron, ductile iron, sintered steel, and hard plastics. This pack of 10 drill bits provides a good stock for your workshop.
