Irwin 1882783 3/16″ #10 Wood Tapered Countersink

Irwin 1882783 3/16″ #10 Wood Tapered Countersink Drill Bit with Adjustable Counterbore

The Irwin 1882783 #10 Wood Tapered Countersink Drill Bit is designed for drilling clean pilot holes and producing smooth, accurate countersinks when working with larger wood fasteners. The tapered high-speed steel drill bit matches the profile of #10 wood screws, helping reduce material splitting while improving fastener holding strength. Widened flutes move chips out of the hole efficiently, allowing faster drilling and cleaner results in softwood, hardwood, plywood, and other common wood materials used in construction and woodworking.

This countersink features an adjustable four-cutter counterbore that cuts evenly and clears chips quickly for smooth, consistent screw seating. The counterbore attaches securely to the flats on the shank using two hex screws and can be adjusted to control pilot hole depth based on screw length and application requirements. A 1/4-inch quick-change hex shank reduces slipping in standard drill chucks and is compatible with all 1/4-inch quick-change systems, including impact drivers. With a compact 4-inch length and durable construction, this bit is well suited for both shop work and jobsite use where accuracy, repeatability, and efficiency are important.
