    Hex-Bit Countersinks for Screws

    Pop these countersinks into power drills, screwdrivers, and other tools that accept hex bits. They create a 90° countersink angle that's compatible with metric flat- and oval-head screws. They're also good for deburring screw holes.

    These versatile, wear-resistant countersinks cut cleanly in most materials, including plastic, aluminum, and steel.
    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.
