KEO Smooth-Finish Six-Flute Countersinks.

Frequently Asked Questions

What is the KEO 100° 6-flute countersink used for?

The KEO 100° 6-flute countersink is designed for creating smooth, burr-free 100° countersunk holes in metal, wood, and plastic. Its six-flute design reduces chatter and vibration, making it ideal for precision deburring and chamfering in aerospace, automotive, and general machining applications.

What are the specifications of the KEO 919-002-507 countersink?

The KEO 919-002-507 is a 100° countersink with six flutes, a 3/4 in body diameter, and an AlTiN coating on cobalt steel. The AlTiN coating provides high heat resistance and extended tool life when machining hard materials. It is manufactured by KEO under MPN 919-002-507.

Where to buy the KEO 919-002-507 countersink worldwide?

How to select the right KEO countersink for your application?

Select a KEO countersink based on the required angle (e.g., 100° for flat-head screws), material hardness, and desired finish. For hard metals, choose AlTiN-coated cobalt like the 919-002-507 for heat resistance. Match the body diameter to your tool holder and ensure flute count suits your feed rate to minimize chatter.
