Frequently Asked Questions

What is the KEO 60° countersink used for?

The KEO 60° countersink is used for deburring and countersinking holes in metal workpieces. Its 60-degree included angle and four-flute design provide smooth cutting action and chip evacuation, making it suitable for precision chamfering in machining and fabrication applications.

What are the specifications of the KEO 60° countersink?

This KEO countersink has a 60° included angle, four flutes, and a 1-inch body diameter. It is made from cobalt steel (MPN 919-000-527) for heat resistance and durability. The four-flute design reduces chatter and improves finish on ferrous and non-ferrous materials.
