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 Lathe Centers

6 Flute
Choose fewer flutes for a faster cut or more flutes for a smoother finish. The 60° countersink angle is compatible with the profile of centers on a lathe.
TiN (titanium nitride) coated countersinks last longer and withstand more heat than black-oxide coated or uncoated countersinks.
