Frequently Asked Questions

What is the KEO 3-flute countersink used for?

The KEO 90° countersink with TiN-coated cobalt is designed for deburring and countersinking holes in metal, steel, and stainless steel. Its three-flute design reduces chatter and provides a smooth finish. Common applications include automotive, aerospace, and general machining where precise 90° chamfers are required.

What are the specifications of the KEO countersink 917-000-214?

This KEO countersink has a 90° included angle, 3 flutes, a 1 3/4 in body diameter, and a 3/4 in shank. It is made from TiN-coated cobalt for extended tool life. The manufacturer part number is 917-000-214. It is a general-purpose tool for industrial deburring and countersinking operations.

Where to buy KEO countersinks worldwide?

How to select the right KEO countersink for your application?

Select a KEO countersink based on material and hole size. For steel or stainless steel, use TiN-coated cobalt tools like the 917-000-214. Match the body diameter to the chamfer size needed. Ensure the shank fits your tool holder. For hard materials, a 3-flute design reduces vibration and improves finish.
