About Countersinks

Countersinks cut a cone-shaped opening to install screws and rivets flush with a surface or hold workpieces between centers on a lathe. They can also be used for chamfering and deburring.

High-Speed Steel Countersinks with
Two Countersinking Ends for Screws

When one end dulls, turn the countersink around for a sharp edge.

Carbide Countersinks for Screws

Cobalt Steel Countersinks for Screws

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

High-Speed Steel Countersinks for Rivets

Carbide Countersinks for Rivets

Often used to cut hard and abrasive materials, these carbide countersinks are harder, stronger, and more wear resistant than cobalt steel and high-speed steel countersinks.

Cobalt Steel Countersinks for Rivets

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