Frequently Asked Questions

What is the KEO 60° countersink used for?

The KEO 60° countersink is designed for deburring and countersinking holes in metal, plastic, and composite materials. Its 60-degree angle and four-flute design provide smooth, chatter-free operation, making it ideal for precision machining in aerospace, automotive, and general manufacturing applications.

What are the specifications of the KEO 917-000-278 countersink?

The KEO 917-000-278 is a 60° countersink with four flutes and a 1 1/4 in body diameter. It features a TiN-coated cobalt construction for enhanced wear resistance and heat dissipation. The manufacturer part number is 917-000-278, and it is designed for use in industrial machining operations.

Where to buy the KEO 60° countersink worldwide?

3G Electric supplies the KEO 60° countersink worldwide. As a global industrial equipment distributor, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time; we source and deliver this TiN-coated cobalt countersink to meet your production needs.

How to select the right KEO countersink for my application?

Select the KEO countersink based on the required angle (60° for standard countersinking), material (TiN-coated cobalt for hard metals), and body diameter (1 1/4 in for larger holes). Match the flute count to your material—four flutes reduce vibration. Consult your machining parameters for optimal feed and speed.
