Frequently Asked Questions

What is a KEO 6-flute countersink used for?

A KEO 6-flute countersink creates smooth, chatter-free 60° chamfers on drilled holes for fasteners like screws and rivets. It is commonly used in metalworking, machining, and fabrication to deburr and countersink holes in steel, aluminum, and other materials.

What are the specifications of the KEO 919-000-307 countersink?

The KEO 919-000-307 is a 60° countersink with 6 flutes, a 1/2 in body diameter, and is made from high-speed steel. It is designed for smooth-finish applications and is manufactured by KEO under part number 919-000-307.

Where to buy KEO countersinks worldwide?

3G Electric supplies KEO countersinks like the 919-000-307 to customers worldwide. We handle full logistics, customs clearance, and delivery to your location. Contact us for pricing and lead time on this high-speed steel, 6-flute, 1/2 in body diameter tool.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the required chamfer angle (e.g., 60° for standard fasteners), flute count for finish quality, and body diameter to match hole size. High-speed steel tools like the 919-000-307 suit general metalworking. For harder materials, consider carbide options.
