With the Dewalt DT4770-QZ spade bit, you quickly drill clean 24 mm clearance holes in soft and hard natural wood as well as chipboard. Perfect for plumbing, electrical, and carpentry projects where running cables and pipes needs to happen fast and accurately. The precision-ground centre point prevents slipping and penetrates timber immediately, while chamfered outer spurs deliver smooth holes with minimal breakout. Made from durable chrome-vanadium steel with an overall length of 152 mm, the 1/4" hex shank prevents chuck slipping and enables quick bit changes in impact drivers and bit holders.
