Frequently Asked Questions

What is the KEO 120° 6-flute countersink used for?

The KEO 120° 6-flute countersink is used for creating smooth, burr-free 120° countersunk holes in metal, plastic, and composite materials. 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 919-002-474 countersink?

The KEO 919-002-474 is a 120° countersink with six flutes, a 1/2 in body diameter, and an AlTiN (aluminum titanium nitride) coating on cobalt steel. It is designed for smooth-finish countersinking and is manufactured by KEO under MPN 919-002-474.

Where to buy the KEO 919-002-474 countersink worldwide?

You can source the KEO 919-002-474 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 cutting tools to industrial buyers globally.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the required angle (e.g., 120° for standard flat-head screws), flute count (6-flute for smoother finish), body diameter matching the hole size, and coating (AlTiN for heat resistance on hard materials). Always match the tool to your material and desired surface finish for optimal results.
