Select the hammer/drill mode appropriate for masonry. Mark the drilling location and position the bit squarely against the surface. Start drilling at low speed to create a guide recess, then apply steady pressure while allowing the tool to do the work. Withdraw the bit periodically to clear debris when drilling deep holes. After finishing, remove dust from the hole before inserting anchors or fixings. Usage recommendations Use appropriate personal protective equipment, including eye protection, hearing protection and dust mask. Match drill length to the required hole depth to avoid unnecessary bit flexing. For reinforced concrete, verify armoring location before drilling and use a bit designed for rebar contact if needed. ## FAQ ### How much does the Masonry drill bit Irwin 12 mm 300/400 mm cost, and is it available for purchase?
