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 are best for aggressive cutting. They leave more room for chips to clear, reducing friction and heat. Countersinks with more flutes spread the cut across more edges for better stability, a smoother finish, and longer tool life.
