Product Description

KEO Anti-Vibration Zero-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 flat-head screws in metalworking. Its zero-flute, anti-vibration design reduces chatter and improves surface finish, making it ideal for precision deburring and countersinking in industrial machining applications.

What are the specifications of the KEO 60° countersink?

The KEO 60° countersink has a 60-degree included angle, 0 flutes, a 1/2 in body diameter, and a 5/16 in shank. It is made of cobalt steel for durability. The manufacturer part number is 919-000-189.

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 screw head angle (e.g., 60° for metric flat-head screws) and the required body diameter to match the screw head size. For hard materials, choose cobalt steel for heat resistance. Ensure the shank fits your tool holder.
