KEO Smooth-Finish Six-Flute Countersinks.

Frequently Asked Questions

What is a KEO 120° 6-flute countersink used for?

This KEO countersink creates smooth, burr-free 120° chamfers on drilled holes in metal. Its six-flute cobalt design provides chatter-free operation and a fine finish, ideal for aerospace, automotive, and general machining applications where precision countersinking is required.

What are the specifications of the KEO 919-000-903 countersink?

The KEO 919-000-903 is a 120° countersink with six flutes, a 2-inch body diameter, and a 3/4-inch shank. It is made from cobalt steel for heat resistance and durability. This smooth-finish tool is designed for use in drill presses, milling machines, or handheld drills.

Where to buy KEO countersinks worldwide?

3G Electric supplies KEO countersinks like the 919-000-903 to customers worldwide. We handle full logistics, customs clearance, and delivery to your site. Contact us for pricing and lead time on this six-flute, 120° cobalt countersink for precision chamfering.

How to select the right KEO countersink for your application?

Choose a KEO countersink based on hole angle (e.g., 120°), material (cobalt for hard metals), and shank size matching your tool holder. For smooth finishes on steel or stainless, a six-flute design reduces chatter. Confirm body diameter clears the workpiece and that RPM matches tooling recommendations.
