KEO Fast-Cutting Single-Flute Countersinks.

Frequently Asked Questions

What is a KEO 110° countersink used for?

A KEO 110° countersink is used to create a conical recess for flat-head screws or to deburr holes in metal. Its single-flute cobalt design provides fast cutting and long life in hard materials like stainless steel, common in machining and fabrication.

What are the specifications of the KEO 55459 countersink?

The KEO 55459 is a 110° single-flute countersink with a 2-inch body diameter and a 3/4-inch shank, made from cobalt steel. It is designed for fast cutting in tough materials and is ideal for industrial machining applications.

Where to buy KEO countersinks worldwide?

3G Electric supplies KEO countersinks like the 55459 to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this cobalt single-flute tool.

How to select the right KEO countersink for your job?

Match the countersink angle (110°) to your screw head angle. Choose a single-flute design for fast chip removal in softer metals, or a multi-flute for smoother finish. Cobalt material suits harder workpieces. Verify shank size fits your tool holder.
