The DEWALT DW2570 is a number 12 countersink with a 7/32-inch drill bit designed for screw driving applications. This countersink bit creates a flush or recessed seat for screw heads in wood and similar materials, allowing fasteners to sit clean without splitting or raised edges. It is sold as an individual unit and is a standard accessory used by carpenters, finish installers, and general contractors who need consistent countersink profiles when driving number 12 screws. The integrated drill bit reduces the steps required before fastening.
The DW2570 is suited for residential and light commercial woodworking, cabinetry, trim work, and general construction applications where number 12 screws are the fastener of choice. It fits standard drill and driver chucks and works with corded or cordless drills. Installers use it when pre-drilling and countersinking in a single pass is preferred over separate operations.
Designed as an OEM-style accessory for use with standard drill and driver chucks accepting countersink bit shanks, suited for number 12 screw driving applications.
Install into a standard drill or driver chuck and tighten securely before use. Ensure the drill is unpowered and the chuck is fully locked before beginning work. Follow applicable safety guidelines for rotating cutting tools when operating at speed. Inspect the bit for wear or damage before each use and replace if the cutting edges are dull or chipped.
