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. This single-flute, 5/8 in body diameter cobalt tool is ideal for machining, fabrication, and maintenance across industrial departments.

What are the specifications of the KEO 919-000-679 countersink?

The KEO 919-000-679 is a fast-cutting single-flute countersink with a 120° included angle, 5/8 in body diameter, and cobalt construction. It is designed for use in drill presses or handheld tools for precise chamfering and deburring.

Where to buy KEO countersinks worldwide?

3G Electric supplies KEO countersinks like the 919-000-679 to customers worldwide. We handle full logistics, customs clearance, and delivery, ensuring you receive genuine industrial tooling for your machining or maintenance operations.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the screw head angle (e.g., 120° for metric flat-head screws) and material. Cobalt tools suit harder metals like stainless steel. Match the body diameter to your hole size and ensure proper RPM for clean cuts.
