    Quick-Change Hex Drill-Bit Countersinks for Wood and Plastic

    Switch bits instead of tools to simplify jobs. These snap directly into drills, power screwdrivers, and other tools that accept a 1/4" hex shank. You can slide the countersink up and down the drill bit and then secure it with a set screw, so one tool will drill countersunk holes for screws of different lengths. These countersinks cut a smooth and even finish in wood and plastic on the first pass.

    Manufacturer—We source from trusted manufacturers who vet raw materials for purity and use diamond grinding wheels to machine precise edges. This keeps cutting surfaces smooth and free of microscopic burrs. Because our suppliers clean their wheels more often than other manufacturers, each countersink is consistently ground to create uniform holes every time.
