KEO Four-Flute Machine Countersinks.

Frequently Asked Questions

What is the KEO 60° countersink used for?

The KEO 60° countersink is used for deburring and chamfering holes in metal workpieces. Its 60-degree included angle and four-flute design provide smooth, chatter-free cutting in industrial machining applications, including aerospace and automotive manufacturing.

What are the specifications of the KEO 60° countersink?

This KEO countersink has a 60° included angle, 4 flutes, a 2-inch body diameter, and a 3/4-inch shank. It features an AlTiN coating on cobalt steel for heat resistance and extended tool life. The manufacturer part number is 917-000-838.

Where to buy the KEO 60° countersink worldwide?

You can source the KEO 60° countersink through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations, ensuring you receive the correct tool for your machining operations.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the required chamfer angle (60° for common screw heads), workpiece material (cobalt with AlTiN coating for hard metals), and shank size matching your tool holder. For high-volume production, the 4-flute design improves chip evacuation and surface finish.
