Product Description

KEO Smooth-Finish Six-Flute Countersinks.

Frequently Asked Questions

What is a KEO 100° countersink used for?

A KEO 100° countersink with six flutes is used to create a smooth, chamfered recess for flat-head screws in metalworking and machining applications. The 100° angle is common in aerospace and automotive industries for flush fastening.

What are the specifications of the KEO 919-000-422 countersink?

The KEO 919-000-422 is a 100°, six-flute countersink with a 5/8 in body diameter, made from high-speed steel. It is designed for smooth-finish countersinking in ferrous and non-ferrous materials, providing chatter-free operation.

Where to buy KEO countersinks worldwide?

3G Electric supplies KEO countersinks like the 919-000-422 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 tool.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the required angle (e.g., 100° for aerospace fasteners), flute count for finish quality, and body diameter matching the screw head. High-speed steel suits general machining; ensure RPM matches material hardness for optimal chip evacuation.
