How to use

Select a drill with a compatible chuck for an 8 mm straight shank. Mark the drilling point, start at low speed to create a guide impression, then increase speed and, if available, use hammer mode for reinforced concrete. Apply steady pressure and periodically withdraw the bit to clear dust and debris from the hole. Use appropriate personal protective equipment including eye protection, hearing protection and dust mask when drilling into concrete or masonry.

Usage recommendations

For best results, match drill speed and hammer action to the material density; use lower speed and hammer action for dense concrete and higher speed without hammer for softer masonry. Replace bits from the pack when wear causes reduced cutting performance or increased wobble to maintain hole accuracy and anchoring strength.
