DEWALT 5/8 in. High Speed Steel Countersink Bit

The DEWALT 5/8 in. High Speed Steel Countersink Bit is your go-to tool for achieving precise, flush screw heads in woodworking and light gauge metalwork. Designed for durability and clean chamfers, this bit delivers reliable performance project after project.

• Countersink diameter: 5/8" for standard flat-head screws, producing a clean, wide chamfer that seats screws flush with the surface.
• Countersink angle: 82 degrees, optimized to create a precise bevel that matches common screw head profiles in cabinetry, furniture, and trim work.
• Shank compatibility: 1/4" round shank fits securely in most drill chucks for stable, wobble-free operation.
• Material and construction: Made from high-speed steel to maintain edge life and resist wear during repeated countersinking across softwood, plywood, and light metals.
• Packaging: Carded, single-piece design for easy storage and quick replacement when you’re mid-project.

Why choose this countersink bit? The DEWALT name stands for durability and precision, and the 5/8" countersink size with an 82° angle provides predictable results that help you avoid over- or under-cutting. This is especially valuable for beginners learning to set screw heads flush or for seasoned woodworkers who need fast, repeatable results without reworking edges.

Ideal applications include cabinetry and kitchen installation, furniture making, door and trim work, and deck-fastening projects where a clean, flush head appearance matters. Pair this bit with common wood screws and a steady drilling technique to achieve professional-looking finishes with minimal effort.

Practical tips for best results: - Start with a pilot hole appropriate to the wood species to minimize splitting, then use the 82° countersink to create a precise bevel for the screw head. - Drill at a steady, moderate speed and back off occasionally to prevent heat build-up and maintain edge sharpness. - Clean away dust between passes to monitor depth and avoid over-countersinking. - Use with a standard drill chuck that accepts a 1/4" round shank for secure operation.
