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

For general purpose use.

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

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

For use on hard-to-machine materials, these countersinks are cobalt steel for better heat and abrasion resistance than high-speed steel.

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.

Use on plastic and most metals.

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.

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