Frequently Asked Questions

What is a KEO 100° countersink used for?

A KEO 100° countersink is used to create a conical recess in metal or plastic for flat-head screws or rivets. The 100° angle is common in aerospace and sheet-metal work. Its six-flute design produces a smooth finish and reduces chatter during operation.

What are the specifications of the KEO 919-000-436 countersink?

The KEO 919-000-436 is a 100°, six-flute countersink made from high-speed steel. It has a 1 3/4 in body diameter and a 3/4 in shank. This tool is designed for smooth-finish applications and is suitable for use in drill presses or handheld tools.

Where to buy KEO countersinks worldwide?

KEO countersinks are available to order through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for pricing and lead time on the KEO 919-000-436 or other models.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the screw head angle (e.g., 100° for aerospace), material (high-speed steel for general use), and shank size matching your tool holder. For a smooth finish on steel or aluminum, the six-flute design reduces vibration. Always match body diameter to the recess depth needed.
