KEO Smooth-Finish Six-Flute Countersinks.

Frequently Asked Questions

What is the KEO 6-flute countersink used for?

The KEO 6-flute countersink is used for creating smooth, burr-free 90° chamfered holes in metal and other materials. Its six-flute design reduces chatter and vibration, making it ideal for precision deburring and countersinking in industrial machining, automotive, and aerospace applications.

What are the specifications of the KEO 919-002-729 countersink?

The KEO 919-002-729 is a 90° countersink with six flutes and a 3/8 in body diameter. It features an AlTiN (aluminum titanium nitride) coating on high-speed steel for extended tool life and heat resistance. This smooth-finish countersink is designed for precise, chatter-free operation in ferrous and non-ferrous materials.

Where to buy the KEO 919-002-729 countersink worldwide?

You can source the KEO 919-002-729 countersink through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we supply genuine KEO tooling for your machining needs.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the required chamfer angle (90° for standard fasteners), flute count (6-flute for smoother finish), and body diameter matching your hole size. The AlTiN coating suits high-speed machining of hardened steels. Always match the tool to your material and machine RPM for optimal results.
