1882781 Countersink Bit, #6 Tapered, 9/64 In. Dia, 1/4 In. Shank

This Irwin tapered countersink bit is designed for drilling fast, clean pilot holes in wood for screws. The #6 size with 9/64 inch diameter makes it ideal for cabinetry, furniture making, and detailed trim work where precise pilot holes and countersinking are essential. The bit's widened flutes help drill efficiently without clogging, while the adjustable four-cutter counterbore cuts and clears chips quickly for smooth, professional countersinking results.

The 1/4 inch quick change shank reduces slipping in standard chucks and is compatible with all 1/4 inch quick change chucks, including impact drills. The counterbore attaches securely to the flats on the shank with hex screws and adjusts for controlled pilot hole depth, giving you precise control over your woodworking projects.
