Product Description

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 countersinking holes in metal, creating a conical seat for flat-head screws. It is common in aerospace, automotive, and general machining applications where precise chamfer angles are required.

What are the specifications of the KEO 60° countersink?

This KEO countersink has a 60° included angle, 4 flutes, a 7/8 in body diameter, and a TiN-coated cobalt construction. The manufacturer part number is 919-000-526. It is designed for use with machine tools and drill presses.

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. Contact us for availability and lead time.

How to select the correct KEO countersink for your application?

Select a KEO countersink based on the required chamfer angle (e.g., 60° for standard flat-head screws), body diameter matching hole size, and material compatibility. TiN-coated cobalt tools offer wear resistance for harder metals. Consult the manufacturer's recommendations for optimal feed and speed.
