Frequently Asked Questions

What is the KEO 82° countersink used for?

The KEO 82° zero-flute countersink is designed for creating clean, chatter-free countersunk holes in metal and composite materials. Its anti-vibration geometry and TiN coating reduce friction and extend tool life, making it ideal for precision deburring and countersinking in aerospace, automotive, and general machining applications.

What are the specifications of the KEO 919-000-203 countersink?

The KEO 919-000-203 is an 82° included-angle, zero-flute countersink with a 5/16 in body diameter. It features a TiN-coated cobalt substrate for wear resistance and anti-vibration design. The manufacturer part number is 919-000-203, and it is produced by KEO.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the required countersink angle (e.g., 82° for standard flat-head screws), material hardness (TiN-coated cobalt for tough alloys), and body diameter matching your hole size. For anti-vibration needs, choose zero-flute designs to minimize chatter and improve surface finish.
