The Irwin 1882784 is a #12 wood-boring countersink tool paired with a 7/32" tapered drill bit, designed for heavier-duty woodworking and fastening applications where a larger screw size is required.

• Design & Performance: Like the rest of the series, it features a tapered drill bit with widened flutes for efficient chip removal and fast, clean pilot hole creation. The four-cutter counterbore provides a consistent and smooth finish, ensuring that #12 flat-head screws seat properly.

• Adjustability & Secure Fit: The counterbore is adjustable, allowing you to set the perfect depth for your project and lock it in place with two hex screws for a secure, wiggle-free fit.

• Quick-Change Compatibility: The 1/4" hex quick-change shank ensures high compatibility with standard drill chucks and impact drivers, preventing the tool from slipping while under load.
