Product Description

KEO Anti-Vibration Zero-Flute Countersinks.

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 a clean, chatter-free 90° countersink in metal, plastic, or wood. Its zero-flute design reduces vibration and improves surface finish, making it ideal for precision deburring and countersinking in machining and fabrication applications.

What are the specifications of the KEO 919-002-827 countersink?

The KEO 919-002-827 is a 90° countersink with a 3/8 in body diameter, 0 flutes, and an AlTiN-coated cobalt construction. It is designed for anti-vibration performance and is suitable for use on a variety of materials. The part number is 919-002-827.

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 919-002-827 or other KEO tooling.

How to select the right KEO countersink for your application?

To select the right KEO countersink, match the body diameter and angle (e.g., 90°) to your fastener or hole requirement. For hard materials, choose AlTiN-coated cobalt for heat resistance. Zero-flute designs reduce vibration, while multi-flute options suit softer materials. Consult KEO's catalog for specific recommendations.
