Choose the right countersink angle, body diameter, and number of flutes for your application.
Countersinks for Rivets
Cut a cone-shaped opening in a hole to install your rivet flush with the surface. The 100°, 110°, and 120° countersink angles are compatible with standard rivet heads.
Cobalt Steel

Tough and wear resistant, these countersinks last at least twice as long as high-speed steel. They can also run up to 25% faster at higher temperatures without chipping on hard materials, such as nickel.
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.
