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 Screws

Choose fewer flutes for a faster cut or more flutes for a smoother finish. An 82° countersink angle is compatible with the profile of flat- and oval-head inch screws; a 90° countersink angle is compatible with the profile of flat- and oval-head metric screws and is also good for deburring.
TiN (titanium nitride) coated countersinks last longer and withstand more heat than black-oxide coated or uncoated countersinks.
