Frequently Asked Questions

What is the KEO 100° countersink used for?

The KEO 100° countersink is designed for creating chamfered holes in metal, plastic, or composite materials. Its three-flute design provides smooth cutting and reduced chatter, making it ideal for deburring and countersinking in general machining, automotive, and aerospace applications.

What are the specifications of the KEO 917-000-812 countersink?

The KEO 917-000-812 is a 100° countersink with three flutes and a 1/4 in body diameter. It features an AlTiN coated carbide construction for extended tool life and heat resistance. The MPN is 917-000-812, and it is a general-purpose three-flute countersink from KEO.

Where to buy KEO countersinks worldwide?

You can source KEO countersinks like the 917-000-812 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 times on this KEO tool.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the required chamfer angle (e.g., 100°), material being cut, and tool coating. For hard metals, choose AlTiN coated carbide like the 917-000-812. Match the body diameter to your hole size and ensure the flute count suits your finish needs—three flutes reduce vibration.
