Frequently Asked Questions

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

The KEO 100° 6-flute countersink is used for creating smooth, burr-free 100° countersunk holes in metal, plastic, and wood. 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 919-000-428 countersink?

The KEO 919-000-428 is a 100° countersink with six flutes and a 7/8 in body diameter, made from high-speed steel. It is part of KEO's Smooth-Finish Six-Flute Countersinks line, designed for clean, chatter-free operation. The manufacturer part number is 919-000-428.

Where to buy the KEO 919-000-428 countersink worldwide?

You can source the KEO 919-000-428 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 KEO cutting tools to procurement teams and engineers globally.

How to select the right KEO countersink for your application?

To select the right KEO countersink, match the included angle (e.g., 100°) to your fastener's head angle, and choose flute count based on material: 6-flute designs like the 919-000-428 reduce chatter in harder metals. Body diameter should clear the hole size. For high-speed steel tools, use moderate speeds and coolant for best results.
