What are the specifications of the KEO 943-000-653 keyseat cutter?

The KEO 943-000-653 is a cobalt keyseat cutter with a 1/2" diameter, 1/8" thickness, 8 teeth, and a staggered-tooth design conforming to ANSI # 404. It is made from cobalt high-speed steel for heat resistance and durability in industrial milling applications.

Where to buy KEO keyseat cutters worldwide?

How to select the right KEO keyseat cutter for a keyway?

Select a KEO keyseat cutter where the cutter thickness matches the keyway width and the diameter matches the required slot depth. For a 1/8" keyway, use the 1/8" thick cutter. Ensure the arbor hole fits your machine. Cobalt steel is ideal for harder materials and longer tool life.
