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 or deburr holes in metalworking. Its single-flute design provides fast, chatter-free cutting in steel, aluminum, and other materials. Ideal for precision chamfering in industrial machining and fabrication.

What are the specifications of the KEO 60° countersink?

This KEO countersink has a 60° included angle, 1 flute, 1 3/4 in body diameter, and 3/4 in shank diameter. It is made of high-speed steel (HSS) for durability. The manufacturer part number is 919-000-179. It is designed for fast cutting in rigid setups.

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. We supply genuine KEO tooling for industrial applications.

How to select the correct KEO countersink for my application?

Select based on screw head angle (60° for metric flathead), material hardness (HSS for general steel), and shank size matching your tool holder. For deep holes, choose a longer flute length. KEO offers single-flute for fast cutting; multi-flute for smoother finish. Verify body diameter clears the workpiece.
