KEO Smooth-Finish Six-Flute Countersinks.

Frequently Asked Questions

What is the KEO 120° 6-flute countersink used for?

The KEO 120° 6-flute countersink is used for deburring and countersinking 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 919-000-506 countersink?

The KEO 919-000-506 is a 120° countersink with six flutes and a 1 1/4 in body diameter. It is made from high-speed steel (HSS) for durability. This tool is designed for smooth-finish applications and is suitable for use in drill presses and handheld tools.

Where to buy the KEO 120° countersink worldwide?

You can source the KEO 120° 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 times on this KEO tool.

How to select the right KEO countersink for your application?

To select the right KEO countersink, match the angle (e.g., 120°) to your screw head type and choose flute count based on finish quality—six flutes provide smoother results. Ensure body diameter fits your hole size. For high-speed steel tools, use proper cutting speeds to extend tool life.
