Quick drilling
- Web thinning ensure less friction during drilling and therefore less feed force needed.
- The sturdy point grinding with short designed working length enable quick drilling by using cordless and wired drill at construction site and in assembly.
- Highly efficient chip removal
Self-centering
The crosswise grinding ensures an excellent centering effect even on domed surfaces, eliminating the need for center-punching or piloting
Good cutting performance
Cutting material HSCo (M35) contains 5% cobalt provides higher heat resistance and hardness for meeting tough requirements.
