Product Description

KEO Smooth-Finish Six-Flute Countersinks.

Frequently Asked Questions

What is the KEO 55087 countersink used for?

The KEO 55087 is a 110°, 6-flute countersink used for deburring and chamfering holes in metal, plastic, and wood. Its six-flute design produces a smooth finish and reduces chatter, making it ideal for precision machining and assembly work in industrial manufacturing.

What are the specifications of the KEO 55087 countersink?

The KEO 55087 is a high-speed steel countersink with a 110° included angle, 6 flutes, and a 5/8 in body diameter. It is manufactured by KEO under part number 55087. The six-flute geometry provides smooth, chatter-free operation for countersinking and deburring applications.

Where to buy the KEO 55087 countersink worldwide?

3G Electric supplies the KEO 55087 countersink worldwide. As a global industrial equipment distributor since 1990, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on this KEO part.

How to select the correct KEO countersink for your application?

Select a KEO countersink based on the required angle (e.g., 110° for standard flat-head screws), flute count (6-flute for smoother finish), body diameter matching the hole size, and material compatibility. High-speed steel suits general-purpose use on metals and plastics. Always match the countersink angle to your fastener.
