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° chamfers on drilled holes in metal and other materials. Its six-flute design reduces chatter and vibration, making it ideal for precision finishing in machining, fabrication, and assembly applications.

What are the specifications of the KEO 919-002-728 countersink?

The KEO 919-002-728 is a 90° countersink with six flutes and a 1/2 in body diameter. It features an AlTiN (aluminum titanium nitride) coating on high-speed steel for increased wear resistance and tool life. The brand is KEO, and the manufacturer part number is 919-002-728.

Where to buy KEO countersinks worldwide?

How to select the right KEO countersink for your application?

Select a KEO countersink based on hole size, material, and desired finish. For general metalworking, a 90° six-flute design like the 919-002-728 reduces chatter. Match the body diameter to your hole size and choose AlTiN coating for harder materials. Always verify RPM and feed rates per manufacturer guidelines.
