DeWalt DT4792 32mm x 406mm Extreme Flat Wood Bit. Features an extra thick steel shank for longer life, tapering to a 1/4" hex. It has chamfered outer cutting spurs for clean, fast drilling and extended life, along with a precision-ground central point for faster material penetration and increased drilling speed. Made from high-quality chrome vanadium, it offers accurate location and clean cutting with a ground chip breaker to reduce splintering and improve drilling efficiency. The heavy-duty full-length heat-treated shank provides maximum durability against bending and breaking. The 1/4" hex fitting prevents slipping in drill chucks and a hang hole allows for bit storage and wire pulling. Suitable for rapid drilling of holes in hardwood and softwood, lumber, and wood with nails, these drill bits can withstand accidental contact with nails buried in timber.
