Product Description

KEO Smooth-Finish Six-Flute Countersinks.

Frequently Asked Questions

What is the KEO 60° 6-flute countersink used for?

The KEO 60° 6-flute countersink is used for deburring and countersinking holes in metal, plastic, and wood. Its six-flute design provides a smooth finish and reduces chatter. It is commonly used in machining, fabrication, and assembly operations where precise 60° chamfers are required.

What are the specifications of the KEO 919-000-321 countersink?

The KEO 919-000-321 countersink has a 60° included angle, 6 flutes, and a 1 1/4 in body diameter. It is made of high-speed steel (HSS) for durability. The manufacturer part number is 919-000-321, and it is designed for smooth-finish applications in industrial settings.

Where to buy the KEO 60° countersink worldwide?

You can source the KEO 60° countersink worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time; we provide reliable sourcing for this and other KEO tooling.

How to select the right KEO countersink for your application?

To select the right KEO countersink, match the angle (e.g., 60°) to your fastener or chamfer requirement. Choose flute count based on finish: 6-flute designs like this one minimize chatter for smooth results. Ensure body diameter (1 1/4 in) fits your tool holder. KEO high-speed steel tools suit general-purpose machining.
