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. The 100° angle is common in aerospace and precision machining. The cobalt construction provides heat resistance for use on hardened steels and stainless alloys.

What are the specifications of the KEO 919-000-831 countersink?

The KEO 919-000-831 is a 100°, six-flute countersink with a 2-inch body diameter and a 3/4-inch shank. It is made from cobalt for durability in high-temperature machining. This smooth-finish design reduces chatter and delivers a clean surface for fastener seating.

Where to buy KEO countersinks worldwide?

3G Electric supplies KEO countersinks like the 919-000-831 to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. As a global industrial sourcing partner, we provide genuine KEO tooling without requiring a local distributor.

How to select the right KEO countersink for your application?

Match the countersink angle to your fastener head — 100° is common for aerospace screws. Choose flute count based on finish: six flutes reduce vibration for smoother results. Cobalt material suits harder workpieces. Confirm shank diameter fits your toolholder before ordering.
