Dwamdb48cs Countersink Bit, 3/4 In. 82° Hss, 1/4 In. Round Shank

The DeWalt DWAMDB48CS countersink bit is a precision-engineered tool designed to create clean, professional-grade recesses in metal, wood, and plastic materials. A countersink bit prepares screw holes so that flat-head screws sit flush with the surface, eliminating snags and producing a smooth, finished appearance. This essential drill accessory is widely used in cabinetry, furniture assembly, automotive repair, metal bracket installation, and general DIY projects where fastener heads must be recessed below the work surface.

The 82-degree angle geometry creates a broad, accurate seat that accommodates standard flat-head screw sizes (#6–#8 and similar fasteners), while the 3/4-inch cutting diameter ensures versatility across common fastener applications. The 1/4-inch round shank provides secure engagement in standard drill chucks, ensuring accurate alignment and consistent positioning. Built from high-speed steel (HSS), this bit resists wear and heat, maintaining its sharp cutting edges through countless projects.
