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

Pop these countersinks into power drills, screwdrivers, and other tools that accept 1/4" hex shanks. Tools grip their hex shanks more securely than round shanks to tackle jobs that require higher torque.

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.

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.

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

Use in general purpose applications.

For general purpose use.

For applications where the workpiece will go through several machining processes, these countersinks bevel the outer edges of the hole and provide an additional 120° chamfer to prevent damage to the center hole.

For general purpose use.

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

Also called subland drill bits. The 90° countersink angle guides the tap into the hole.
