Product Description

KEO Smooth-Finish Six-Flute Countersinks.

Frequently Asked Questions

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

This KEO countersink creates smooth, burr-free 100° chamfers on drilled holes in metal, plastic, and wood. Its six-flute design reduces chatter and vibration, making it ideal for precision deburring and countersinking in machining, fabrication, and maintenance applications.

What are the specifications of the KEO 919-000-416 countersink?

The KEO 919-000-416 is a 100° countersink with six flutes, a 3/8 in body diameter, and is made from high-speed steel. It is designed for smooth-finish countersinking and is manufactured by KEO under part number 919-000-416.

Where to buy KEO countersink 919-000-416 worldwide?

3G Electric supplies the KEO 919-000-416 countersink to customers worldwide. We handle full logistics, customs clearance, and delivery to your site. Contact us for pricing and lead time on this high-speed steel, six-flute countersink.

How to select the right KEO countersink for your application?

Choose a KEO countersink based on the required chamfer angle (100° for standard flat-head screws), material hardness (high-speed steel for general metals), and hole size (3/8 in body diameter for smaller holes). Six-flute designs minimize vibration for smoother finishes.
