Irwin 1882782 No 8 Wood Countersink Tapered Drill Bit

Product Description

The IRWIN INDUSTRIAL TOOL CO 1882782 is a No. 8 wood countersink with a tapered drill bit designed to cut clean, fast pilot holes in wood. Widened flutes clear chips efficiently, while the 4-cutter adjustable counter bore allows controlled depth adjustment for smooth countersinking. The counter bore attaches securely to the shank flats via hex screws. A 1/4 inch quick-change shank reduces slipping in standard chucks and is compatible with impact drills. This tool is suited for fine woodworking applications where flush or recessed fastener seating is required. Licensed tradespeople and skilled woodworkers install this bit using standard or impact drills.

The 1882782 countersink is intended for wood fastening applications in residential finish carpentry, cabinetry, furniture building, and general fine woodworking. The adjustable counter bore accommodates controlled pilot hole depth, making it useful for projects that require consistent screw-seat depth across multiple fasteners. The 1/4 inch quick-change shank fits all 1/4 inch quick-change chuck systems, including impact driver platforms, broadening its usability across common tool inventories. This unit is sold as a package of 6.
