With the Dewalt DT4768-QZ spade bit, you drill rapidly and cleanly through hardwood, softwood, chipboard, and man-made wood materials. The optimised centre point bites instantly into the timber, while chamfered outer spurs score the wood fibres first to deliver neat, breakout-free hole edges. Thanks to the robust 1/4" hex shank made of chrome vanadium steel, the bit will not slip in your chuck and fits directly into standard bit holders, drill drivers, and impact drivers. Featuring a 20 mm cutting diameter and an overall length of 152 mm, it provides efficient drilling for running cables and plumbing conduits.
