KEO Fast-Cutting Single-Flute Countersinks.

Frequently Asked Questions

What is the KEO 60° countersink used for?

The KEO 60° countersink is used to create a conical recess for flathead screws in metalworking and machining applications. Its single-flute design provides fast, chatter-free cutting in materials like steel and aluminum, making it ideal for deburring and countersinking holes in industrial manufacturing.

What are the specifications of the KEO 919-000-556 countersink?

The KEO 919-000-556 is a 60° countersink with a single flute and a 3/8 in body diameter. It features a TiN (titanium nitride) coating on cobalt steel for increased hardness and wear resistance. This fast-cutting tool is designed for precision countersinking in metalworking.

Where to buy the KEO 60° countersink worldwide?

You can source the KEO 60° countersink worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on the KEO 919-000-556 countersink.

How to select the right KEO countersink for your application?

Select the KEO countersink based on the screw head angle (60° for standard flathead screws), material hardness (TiN-coated cobalt for tough alloys), and body diameter matching the hole size. For general metalworking, the single-flute design offers fast cutting with minimal vibration.
