Important:
Wet and dry-drilling core bits are designed for
a drilling contact pressure of 250 N (25 kg). In-
sufficient pressure can lead to polishing of the
segments and a reduction of drilling perfor-
mance. Polished/blunt core bits can be
resharpened e.g. using the Hilti sharpening
plate (item no. 51343/3).
