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.

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

The built-in pilot maintains alignment in the hole.

To create smooth cuts and prevent chips from clogging the tool, these countersinks have an angled hole that passes through the center of the tool for reduced vibration and chatter.

When one end dulls, turn the countersink around to use the other end. An angled hole passes through the center of the countersink to reduce vibration and chatter, which creates smooth cuts and prevents 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.

For use with computer-controlled machines, these highly accurate countersinks have a tolerance of 0" to +0.001".

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.

The 82° countersink angle is compatible with the profile of flat- and oval-head inch screws.

Use in general purpose applications.

For general purpose use.

These countersinks create a surface that minimizes contact between the material and the lathe centers to prevent damage and allow for more precise machining.

For general purpose use.

These countersinks come attached to a high-speed steel jobbers’ bit.
