The IRWIN 1882782 No. 8 Tapered Countersink Drill Bit is engineered for precision woodworking, delivering clean pilot holes and consistent countersinks in a single pass. Constructed from durable high-speed steel, this bit features a tapered design with widened flutes for efficient chip removal and reduced wood splitting. The adjustable four-cutter counterbore allows for precise depth control and is securely fastened to the 1/4-inch quick-change hex shank, which is compatible with both standard and impact drills. Ideal for professional cabinetry and construction, it ensures a perfect fit for #8 wood screws while maintaining high-speed performance.

Tapered drill with widened flutes for drilling fast, clean pilot holes. 1/4 in quick change shank reduces slipping in standard chucks and is compatible with all 1/4 in quick change chucks, including impact drills.

We also give you the ability to change a GL Code for one or all items for renovation projects that may utilize a single GL Code. We can also code any of our "extended inventory" items with your General Ledger Code at the time of quote, order confirmation and invoicing as well. We can code our item numbers directly to your GL Codes should our item categories not align directly with your GL Code Categories.
