⚙Technical parameters
- 5-pcs drill bit set with Step-Tip point - HSS-Co DIN 338
- Design:
- DIN 338, Type N, right-hand cutting
- made from cobalt-alloyed steel, cobalt content 5%
- metal drill bits also suitable for stainless steel and other hard materials
- special Step-Tip point - more precise starting, the drill does not wander and cuts into the material better
- thanks to the stepped point, pre-drilling with smaller diameters is not required - the drill reaches the required diameter in one step without changing tools
- point with TiN coating - higher resistance and longer point life
