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

More heat and abrasion resistant than high-speed steel, cobalt steel has better performance on hard-to-machine materials.

The built-in pilot maintains alignment in the hole.

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.

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