Product Description

KEO Fast-Cutting Single-Flute Countersinks.

Frequently Asked Questions

What is a KEO 120° countersink used for?

A KEO 120° countersink creates a conical recess for flat-head screws or deburrs holes in metal. Its single-flute design and TiN-coated cobalt construction deliver fast, clean cutting in hardened steels and alloys across machining, fabrication, and maintenance applications.

What are the specifications of the KEO 919-000-678 countersink?

The KEO 919-000-678 is a 120° single-flute countersink with a 1/2 in body diameter. It features a TiN-coated cobalt substrate for wear resistance and heat dissipation. This tool is designed for high-speed, burr-free countersinking in ferrous and non-ferrous materials.

Where to buy KEO countersinks worldwide?

3G Electric supplies KEO countersinks like the 919-000-678 to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact our team for a quote and lead time on this and other KEO cutting tools.

How to select the right KEO countersink for your job?

Match the countersink angle (e.g., 120°) to your fastener head angle. Choose flute count based on material: single-flute tools like this KEO model cut aggressively in metals. TiN coating extends tool life in abrasive alloys. Confirm body diameter fits your drill chuck or holder.
