The Irwin 1882782 is a #8 wood-boring countersink tool paired with an 11/64" tapered drill bit. Like its smaller counterpart, it is designed for precision woodworking, allowing you to drill a pilot hole, countersink, and counterbore in one fluid motion.

• Design & Performance: The 11/64" tapered drill bit is optimized to create a pilot hole that matches the profile of a #8 screw, which helps prevent the wood from splitting. The integrated four-cutter counterbore provides a clean, professional finish for the screw head.

• Adjustability: You can adjust the counterbore depth using the included hex screws to achieve the perfect depth for your project. The tool also features an adjustable stop collar to ensure that every hole is countersunk to the exact same depth.

• Compatibility: This tool is equipped with a 1/4" hex quick-change shank. This makes it fully compatible with standard drills and impact drivers, and helps prevent the bit from slipping in the chuck during use.
