The Irwin 1882783 is a #10 wood-boring countersink tool with a 3/16" tapered drill bit, designed to deliver professional-grade results for woodworking projects.

• Tapered Precision: The 3/16" tapered bit features widened flutes, which are specifically engineered to drill clean pilot holes quickly, ensuring an optimal, tight fit for #10 screws.

• Adjustable Counterbore: It includes an adjustable four-cutter counterbore that cuts and clears chips efficiently, allowing for smooth, consistent countersinking. The counterbore attaches securely to the shank with two hex screws, giving you precise control over the depth of the pilot hole and the countersink.

• Versatile Shank: With a 1/4" quick-change shank, this tool is designed to resist slipping in standard chucks and is fully compatible with any 1/4" quick-change chuck, including impact drivers.
