Frequently Asked Questions

What is the KEO 60° countersink used for?

The KEO 60° countersink is used for deburring and countersinking holes in metal, plastic, and wood. Its 60-degree included angle and four-flute design provide smooth, chatter-free cutting. Common applications include aerospace, automotive, and general machining where precise chamfering is required.

What are the specifications of the KEO 917-000-935 countersink?

The KEO 917-000-935 is a 60° four-flute machine countersink with a 1 1/4 in body diameter. It features AlTiN-coated high-speed steel for extended tool life and heat resistance. The MPN is 917-000-935, and it is designed for use in drill presses and CNC machines.

Where to buy KEO countersinks worldwide?

KEO countersinks are available to order through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact 3G Electric for pricing and lead time on the KEO 917-000-935 or other KEO tooling.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the required chamfer angle (e.g., 60°, 82°, 90°) and material. For hard metals, choose AlTiN-coated high-speed steel like the 917-000-935. Match the body diameter to your hole size and ensure the shank fits your tool holder. Consult KEO's catalog for specific recommendations.
