The 1882781 No. 6 Tapered Countersink Drill Bit is a professional-grade tool designed for creating clean, accurate pilot holes and smooth countersinks in various wood materials. Featuring a high-speed steel tapered bit that matches the profile of #6 wood screws, it significantly reduces wood splitting while maximizing fastener holding power. The adjustable four-cutter counterbore and widened flutes ensure efficient chip removal for faster drilling and a professional finish. Equipped with a 1/4-inch quick-change hex shank, this bit is compatible with standard chucks and impact drivers, making it an essential addition to any woodworking or construction toolkit.

Tapered drill with widened flutes for drilling fast, clean pilot holes. 1/4 in quick change shank reduces slipping in standard chucks and is compatible with all 1/4 in quick change chucks, including impact drills. Adjustable four-cutter counterbore cuts and clears chips quicker for fast, smooth countersinking. Counter bore attaches to flats on shank with two hex screws for a secure fit and can be adjusted for controlled pilot hole depth.
