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.

Carbide Starter-Hole-Eliminating Drill-Point
Countersinks with Two Countersinking Ends for Screws
Turn the countersink around when one end dulls for a sharp cutting edge. There’s no need to create a starter hole since the drill point is incorporated into the countersink flutes. 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.
