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

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.

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

To create a clean, smooth finish on your material, these countersinks have specially designed spiral flutes that reduce chip buildup on the cutting edge.

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

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

The 100° countersink angle is compatible with the profile of rivets.

An angled hole passes through the center of these countersinks to reduce vibration and chatter, creating smooth cuts and preventing chips from clogging the tool.

Carbide is harder, stronger, and more wear resistant than high-speed steel for better performance on hard and abrasive materials.

The 100° countersink angle is compatible with the profile of rivets.

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

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.

Designed 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.

These carbide countersinks are harder, stronger, and more wear resistant than high-speed steel for better performance on hard and abrasive materials.

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

For general purpose use.

Use in general purpose applications.

Carbide is harder, stronger, and more wear resistant than cobalt steel and high-speed steel for better performance on hard and abrasive materials.

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

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

For general purpose use.

Carbide is harder, stronger, and more wear resistant than high-speed steel for excellent performance on hard and abrasive materials.

For use with most metals in addition to plastic and wood.

For excellent performance on hard and abrasive materials, carbide is harder, stronger, and more wear resistant than high-speed steel.

Use in general purpose applications.

Carbide is harder, stronger, and more wear resistant than cobalt steel and high-speed steel for better performance on hard and abrasive materials.

The 100° countersink angle is compatible with the profile of rivets.

The manually powered, angled shank lets you countersink and debur next to a shoulder and in hard-to-access holes.

For a clean, smooth finish on your material, these countersinks have specially designed spiral flutes that reduce chip buildup on the cutting edge.

For better performance on hard and abrasive materials, the carbide countersinks in these sets are harder, stronger, and more wear resistant than high-speed steel countersinks.

Harder, stronger, and more wear resistant than high-speed steel, the carbide countersinks in these sets have better performance on hard and abrasive materials.

The 60° countersink angle is compatible with the profile of centers on a lathe.

Cobalt steel bits are heat resistant and maintain their sharp edges when drilling hard material. They are for use in both hand-held drilling and machine-tool applications.
