Quick drilling
- Web thinning ensure less friction during drilling and therefore less feed force needed
- The optimized point grinding with short designed working length enable quick drilling by using cordless and wired drill at construction site and in assembly
Self-centering
The crosswise grinding ensures an excellent centering effect even on domed surfaces, eliminating the need for center-punching or piloting
