KEO Fast-Cutting Single-Flute Countersinks.

Frequently Asked Questions

What is the KEO 100° countersink used for?

The KEO 100° countersink is used to create a conical recess for flat-head screws in metalworking and machining applications. Its single-flute design provides fast, chatter-free cutting in steel, aluminum, and other materials, making it ideal for deburring and countersinking holes in industrial manufacturing.

What are the specifications of the KEO 919-000-149 countersink?

The KEO 919-000-149 is a 100° countersink with a single flute and a 3/4 in body diameter. It is made from high-speed steel (HSS) for durability and sharpness. This fast-cutting tool is designed for precision countersinking in metalworking, compatible with standard drill chucks.

Where to buy KEO countersinks worldwide?

You can source KEO countersinks 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 times on the KEO 919-000-149 or other KEO tooling.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the screw head angle (e.g., 100° for flat-head screws), body diameter matching the hole size, and material compatibility. High-speed steel (HSS) tools like the 919-000-149 suit general metalworking. For harder materials, consider carbide options. Always match flute count to desired cut finish.
