Product Description

KEO Smooth-Finish Six-Flute Countersinks.

Frequently Asked Questions

What is a KEO 100° countersink used for?

This KEO 100° countersink creates smooth, countersunk holes for flat-head screws in metalworking and machining applications. Its six-flute design reduces chatter and delivers a clean finish, making it suitable for precision deburring and chamfering in industrial manufacturing.

What are the specifications of the KEO 919-000-420 countersink?

The KEO 919-000-420 is a 100°, six-flute countersink with a 1/2 in body diameter, made from high-speed steel. It is designed for smooth-finish countersinking and is compatible with standard drill chucks. The 100° angle suits metric flat-head fasteners.

Where to buy KEO countersinks worldwide?

3G Electric supplies KEO countersinks like the 919-000-420 to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. 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?

Match the countersink angle to your fastener head angle—100° for metric flat-head screws. Choose flute count based on finish: six-flute designs like this KEO model minimize vibration for smoother results. Body diameter must clear the screw head; high-speed steel suits general-purpose machining.
