Frequently Asked Questions

What is a KEO 100° countersink used for?

The KEO 100° countersink with six flutes is designed for creating smooth, burr-free chamfered holes in metal, ideal for aerospace, automotive, and general machining applications where a 100° countersink angle is specified.

What are the specifications of the KEO 55577-TiN countersink?

This KEO countersink has a 3-inch body diameter, 1-inch shank, six flutes, and a 100° included angle. It features a TiN-coated cobalt construction for extended tool life in hard materials. The manufacturer part number is 55577-TiN.

Where to buy KEO countersinks worldwide?

3G Electric supplies KEO countersinks like the 55577-TiN to customers worldwide. We handle full logistics and customs clearance, ensuring reliable delivery for your industrial tooling needs across global markets.

How to select the right KEO countersink for my application?

Match the countersink angle (e.g., 100°) to your fastener or print specification. Choose flute count based on finish: six-flute designs like this KEO model provide smoother finishes. Ensure shank diameter fits your toolholder, and consider coating (TiN) for harder materials.
