Product Description

KEO Smooth-Finish Six-Flute Countersinks.

Frequently Asked Questions

What is a KEO 6-flute countersink used for?

A KEO 6-flute countersink creates smooth, chatter-free 90° chamfers and countersinks in metal. It is ideal for deburring holes and preparing surfaces for flat-head screws in machining, fabrication, and maintenance applications across industrial departments.

What are the specifications of the KEO 919-002-525 countersink?

The KEO 919-002-525 is a 90°, 6-flute countersink with a 3/4 in body diameter. It features an AlTiN coated cobalt construction for heat resistance and extended tool life. This smooth-finish design reduces vibration during operation.

Where to buy KEO countersinks worldwide?

3G Electric supplies KEO countersinks like the 919-002-525 to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this AlTiN coated cobalt tool.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the required chamfer angle (90° for standard flat-head screws), flute count (6-flute for smoother finish), and body diameter matching your hole size. AlTiN coating suits harder materials like stainless steel. Match RPM to tool diameter for best results.
