KEO Smooth-Finish Six-Flute Countersinks.

Frequently Asked Questions

What is the KEO 100° countersink used for?

The KEO 100° countersink is used for creating smooth, chamfered holes in metal and composite materials. Its six-flute design and TiN coating reduce chatter and extend tool life, making it ideal for aerospace, automotive, and general machining applications where a clean finish is required.

What are the specifications of the KEO 919-000-806 countersink?

The KEO 919-000-806 is a 100° countersink with six flutes, a 1/4 in body diameter, and a TiN-coated cobalt construction. It is designed for smooth-finish countersinking in hard materials. The manufacturer part number is 919-000-806, and it is produced by KEO.

Where to buy KEO countersinks worldwide?
