Specification

Assembly drill for general, broad applications in steel up to 850 N/mm² strength and cast iron.

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.
