⚙Technical parameters
- 29-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
- from diameter 2.0 mm, the point has a split point - the drill cuts into the material better and does not require centre punching
- from diameter 4.0 mm, shank with 3 flats (against slipping in the chuck)
- gold-brown finish
- point angle 130°
- Use in materials: alloy steel, non-alloy steel, iron, cast iron, non-ferrous metals, V2A stainless steel, V4A stainless steel, strength up to 1200 N/mm
