Bore quickly and cleanly through timber studs, joists, and sheet materials with the Dewalt DT4766-QZ spade bit. Its optimized center point and dual cutting edges ensure an immediate bite and smooth penetration across hardwood, softwood, chipboard, and nail-embedded wood. Built from tough chrome-vanadium steel with a reinforced shank, this 16mm wood bit delivers outstanding resistance against heavy wear and bending. The 1/4" hex shank prevents slipping in standard chucks and fits directly into quick-release bit holders and impact drivers. This gives you dependable power transfer and complete control when boring 16mm holes for cabling, framing, and pipework.
