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 or deburr holes in metal, plastic, and wood. Its single-flute design provides fast, chatter-free cutting in production and maintenance applications. Ideal for aerospace, automotive, and general fabrication where precise 60° chamfers are required.

What are the specifications of the KEO 919-000-557 countersink?

The KEO 919-000-557 is a 60° single-flute countersink with a 1/2 in body diameter, made from cobalt steel for heat resistance and durability. It is designed for fast cutting and produces a smooth finish. The cobalt material extends tool life when machining harder materials like stainless steel.

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. 3G Electric supplies KEO cutting tools to customers across industries.

How to select the right KEO countersink for your application?

Select the KEO countersink based on the required chamfer angle (60° for standard flathead screws), body diameter matching the screw head size, and material compatibility. Cobalt steel is best for hard metals; high-speed steel suits softer materials. Single-flute designs reduce vibration for cleaner cuts in production runs.
