Frequently Asked Questions

What is the KEO 6-flute countersink used for?

The KEO 6-flute countersink creates smooth, chatter-free 90° countersunk holes in metal, plastic, and wood. Its TiN-coated cobalt construction resists heat and wear, making it ideal for production machining, tool-and-die work, and aerospace or automotive applications where a clean finish is required.

What are the specifications of the KEO countersink 919-000-768?

This KEO countersink has a 90° included angle, 6 flutes, a 3/16 in body diameter, and a 3/16 in shank. It is made from TiN-coated cobalt for extended tool life. The manufacturer part number is 919-000-768, and it is designed for smooth-finish countersinking in hard materials.

Where to buy KEO countersinks worldwide?

Contact us for availability and lead time on the KEO 919-000-768 or other six-flute countersink sizes. We source and deliver to any country.

How to select the right KEO countersink for my application?

Choose a KEO countersink with the same angle as your fastener head—90° is standard for flat-head screws. Match the body diameter to the screw head size. For hard materials like stainless steel, select TiN-coated cobalt for heat resistance. The 6-flute design reduces vibration for a smoother finish.
