Ideally suitable for assembly work in thin-walled materials such as sheet steels, flat steels and profile steels. Highly secure against fracture. For use in all hand-held drilling machines.
HSS:
Heavy-duty high speed steel for drilling holes in easy-to-machine materials with a strength of up to 900 N/mm².
Shape C: Split point
Applications: for drills with very strong cores, for particularly tough, hard materials and for deep-hole drills.
Advantages: good centring, little pressure required. Chip spreading improves chip removal.
Disadvantages: perfect grinding only possible by machine.
