The Relton R4X standard masonry drill bit puts four carbide cutting edges on the point, so impact spreads evenly across the face for faster, smoother drilling with less bit walking. Stocked diameters run 1/8 in. through 1 in. in lengths from 3 to 12 in., for clean anchor and fastener holes in concrete, brick, stone and cinder block.

Four cutters distribute impact to extend bit life in dense material, and wide, deep spiral flutes keep dust moving out of the hole to prevent clogging and overheating. The design comes in SDS-Plus, SDS-Max, hex and standard round shank variations to match your drilling system. For single-tip economy the Ram Tip percussion bit covers a similar hole range, the screw type anchor bit drills matched anchor pilot holes, and the rest of our electric hammer tooling is stocked alongside.
