About Countersinks
Countersinks cut a cone-shaped opening to install screws and rivets flush with a surface or hold workpieces between centers on a lathe. They can also be used for chamfering and deburring.

High-Speed Steel Countersinks for Rivets
6 Flute
Choose fewer flutes for a faster cut or more flutes for a smoother finish. The 100°, 110°, or 120° countersink angle is compatible with the profile of rivets.
TiN (titanium nitride) coated countersinks last longer and withstand more heat than black-oxide coated or uncoated countersinks.

Cobalt Steel Countersinks for Rivets
6 Flute
For better performance on hard-to-machine materials, cobalt steel is more heat and abrasion resistant than high-speed steel. Choose fewer flutes for a faster cut or more flutes for a smoother finish. The 100°, 110°, or 120° countersink angle is compatible with the profile of rivets.
TiN (titanium nitride) coated countersinks last longer and withstand more heat than black-oxide coated or uncoated countersinks.
