The fastest, longest and lightest TYROLIT core bit for dry drilling and hand-held applications. The thread shape of the steel tubes allows easy removal of drilling dust using an extraction system. Spiral grooves noticeably reduce weight. Dry-drilling core bits are also specially adapted for core drilling with a soft-hammer function, and in combination with the TYROLIT DME19DP drilling motor they are therefore the ideal solution for hand-held dry drilling with a longer service life than DDL-HH-FAST CUT.
