How to use

Select the drill bit diameter that corresponds to the anchor or fastener required. Secure the bit in the chuck of a hammer drill or rotary hammer according to the tool manufacturer's instructions. Where applicable, set the tool to hammer or percussion mode and start drilling at low speed to establish the hole, then apply steady pressure and increase speed as appropriate. Clear dust from the hole periodically with a blow or vacuum before inserting anchors or fasteners to ensure correct seating.

Usage recommendations

For best results, use appropriate personal protective equipment including eye protection, hearing protection and dust mask. When drilling deep or large-diameter holes, withdraw the bit occasionally to remove debris and prevent overheating. Match the selected bit diameter to the anchor manufacturer's recommendations to ensure secure fixing.
