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.

The manually powered, angled shank lets you countersink and debur next to a shoulder and in hard-to-access holes. The 90° countersink angle is compatible with the profile of flat- and oval-head metric screws. It’s also good for deburring.
