For rotary drilling only! • Optimum contact pressure 35 - 45 kg • If the recommended drilling speed is observed and the optimum contact pressure applied, but you can no longer hear a "scraping" sound, the drill bit has reached the end of its service life. • Avoid placing high contact pressure on the drill bit when it is not rotating→ Risk of breakage! • Contact pressure too low and/or drilling speed too high → Service life ends prematurely! • Avoid tilting and swivelling movements during the drilling process → Risk of breakage! • We recommend drilling test holes (ideally in waste material from the tiles to be drilled) Application • Rotary drilling in porcelain stoneware tiles, tiles, glass (not safety glass) and porcelain • Ideal for electric and cordless drills Instructions 1. Start the hole with point precision, applying light pressure 2. Switch on the drill 3. Apply full contact pressure → "Scraping" sound must be heard 4. Use reduced contact pressure once the tile has been fully penetrated
