Frequently Asked Questions

What is a KEO 60° countersink used for?

A KEO 60° countersink with four flutes is used to create a conical recess for flathead screws or deburr holes in metal, plastic, or wood. The TiN-coated cobalt construction provides heat resistance and longer tool life in production machining and maintenance applications.

What are the specifications of the KEO 919-000-520 countersink?

The KEO 919-000-520 is a 60° four-flute machine countersink with a 1/2 in body diameter. It features a TiN-coated cobalt substrate for wear resistance. This tool is designed for precision chamfering and deburring in industrial machining operations.

Where to buy KEO countersinks worldwide?

3G Electric supplies KEO countersinks like the 919-000-520 to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact our team for a quote on this tool or other industrial cutting supplies across 14 departments.

How to select the right KEO countersink for your application?

Match the countersink angle (e.g., 60°) to your screw head or chamfer requirement. Choose flute count based on material: four-flute tools like the KEO 919-000-520 provide smoother finishes in metals. TiN coating reduces friction and extends tool life in harder materials.
