KEO General Purpose Three-Flute Countersinks.

Frequently Asked Questions

What is a KEO 110° countersink used for?

A KEO 110° countersink is used to create a conical recess in a workpiece, typically for countersinking flat-head screws or deburring holes. The 110° angle is common in aerospace and sheet-metal applications where flush fastening is required.

What are the specifications of the KEO 50581-TIN countersink?

The KEO 50581-TIN is a general-purpose three-flute countersink with a 110° included angle, 5/8 in body diameter, and TiN-coated high-speed steel construction. The TiN coating reduces friction and extends tool life when machining steel or aluminum.

Where to buy KEO countersinks worldwide?

3G Electric supplies KEO countersinks like the 50581-TIN to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this and other KEO cutting tools.

How to select the right countersink angle for a job?

Select the countersink angle to match the fastener head angle — 82° for standard flat-head screws, 90° for metric, and 110° for aerospace or thin-sheet applications. The KEO 110° three-flute design provides smooth cutting and reduced chatter in harder materials.
