    Smooth-Finish Countersinks for Screws

    Make smooth, uniform cuts without stopping to clear chips. Spiral-flute cutting edges lift chips out of the hole as you cut so they don't clog the tool.

    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.

    Countersink Sets for Screws

    Image of Product. Front orientation. Countersinks. Countersink Sets for Screws.
    Cut cone-shaped recesses for screws of various diameters so the screw head sit flush with the surface. Choose an 82° countersink angle for inch screws or a 90° countersink angle for metric screws.
    High-Speed Steel—These versatile, wear-resistant countersinks cut cleanly in most materials, including plastic, aluminum, and steel.
    Titanium Nitride (TiN) Coated—Withstand heat, corrosion, and abrasion better than uncoated and black oxide countersinks, so they stay sharp over longer periods.
    Number of Flutes—Countersinks with fewer flutes reduce chatter, so you can run them at high speeds. Countersinks with a higher number of flutes remove more material per revolution, leaving a smoother finish and extending tool life.
    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.
