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 Drill-Point Countersink Sets with Two Countersinking Ends for Screws
Turn the countersink around when one end dulls for a sharp cutting edge. The countersinks in these sets have a small drill point on the tip for drilling and countersinking holes with the same tool. The drill point creates a small pilot hole at the bottom of the countersunk hole to facilitate drilling. 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.
