Frequently Asked Questions

What is a KEO anti-vibration zero-flute countersink used for?

A KEO anti-vibration zero-flute countersink is used to create clean, burr-free 90° chamfers and countersinks in metal, plastic, and composite materials. Its zero-flute design minimizes chatter and vibration, making it ideal for precision deburring and countersinking in machining, fabrication, and maintenance applications.

What are the specifications of the KEO 919-000-220 countersink?

The KEO 919-000-220 is a 90° countersink with 0 flutes, a 5/16 in body diameter, and a TiN-coated cobalt construction. The TiN coating increases wear resistance and tool life. It is designed for anti-vibration performance in high-precision countersinking operations.

Where to buy KEO countersinks worldwide?

You can source KEO countersinks worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on the KEO 919-000-220 or other KEO tooling.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the required chamfer angle (e.g., 90°), material hardness, and desired finish. For steel or hard alloys, choose TiN-coated cobalt like the 919-000-220 for durability. Match the body diameter to your hole size and ensure the shank fits your tool holder. Consult KEO's catalog for guidance.
