Frequently Asked Questions

What is a KEO 100° countersink used for?

A KEO 100° countersink creates a conical recess for flat-head screws in metal, wood, or plastic. Its single-flute design provides fast, chatter-free cutting. This TiN-coated cobalt tool is ideal for aerospace, automotive, and general machining applications requiring precise countersinking.

What are the specifications of the KEO 919-000-644 countersink?

The KEO 919-000-644 is a 100° single-flute countersink with a 2-inch body diameter and a 3/4-inch shank. It features a TiN-coated cobalt construction for extended tool life. This fast-cutting design is suitable for use in drill presses and handheld tools.

Where to buy KEO countersinks worldwide?

3G Electric supplies KEO countersinks like the 919-000-644 to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact our team for a quote on this TiN-coated cobalt tool, and we will source and deliver it to your location.

How to select the right KEO countersink for your application?

Match the countersink angle (e.g., 100°) to your fastener's head angle. Choose body diameter larger than the screw head. For hard materials like stainless steel, select TiN-coated cobalt tools from KEO for heat resistance. Single-flute designs offer faster cutting with less vibration.
