How to use

Select the bit size that matches the required starter hole. Secure the bit in the drill chuck, position the centering tip at the marked point, and drill at moderate speed with steady pressure to create a clean starter hole. For tile, use a light touch at first to avoid slipping; increase pressure once the tip has established a groove. After drilling, clean the hole of dust before inserting anchors or fasteners.

Usage recommendations

Use appropriate personal protective equipment (safety glasses and gloves). Match drill speed and pressure to the material — lower speed and steady pressure for tile, moderate speed for concrete. Replace bits when worn to maintain clean holes and accurate centring.
