Specially designed with spiral flutes that reduce chip buildup on the cutting edge, these countersinks produce a clean, smooth finish on your material.

When one end dulls, turn the countersink around for a sharp edge.

These countersinks have an angled hole that passes through the center of the tool to reduce vibration and chatter for creating smooth cuts and preventing chips from clogging the tool.

These highly accurate countersinks have a tolerance of 0" to +0.001", so you can use them with computer-controlled machines.

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.

Use in general purpose applications.

To remove the need for a starter hole, the drill point is incorporated into the countersink flutes.
