Frequently Asked Questions

What is the KEO 6-flute countersink used for?

The KEO 6-flute countersink is used for deburring and countersinking holes in metal, producing a smooth 90° chamfer. Its six-flute design reduces chatter and vibration, making it ideal for precision work on steel, stainless steel, and other alloys in industrial machining and fabrication.

What are the specifications of the KEO countersink 919-000-791?

The KEO countersink model 919-000-791 has a 90° included angle, 6 flutes, 1 1/2 in body diameter, and 3/4 in shank diameter. It is made from cobalt steel for heat resistance and durability, designed for smooth-finish countersinking in hard materials.

How to select the right KEO countersink for your application?
