Product Description

KEO Smooth-Finish Six-Flute Countersinks.

Frequently Asked Questions

What is the KEO 100° 6-flute countersink used for?

The KEO 100° 6-flute countersink is used for creating smooth, burr-free 100° countersunk holes in metal, plastic, and composite materials. Its six-flute design reduces chatter and vibration, making it ideal for precision deburring and chamfering in aerospace, automotive, and general machining applications.

What are the specifications of the KEO 919-000-811 countersink?

The KEO 919-000-811 is a 100° countersink with six flutes and a 1/2 in body diameter. It is made from cobalt steel for durability and heat resistance. The smooth-finish design ensures clean, consistent cuts. This tool is suitable for use in CNC and manual machines.

Where to buy the KEO 919-000-811 countersink worldwide?

You can source the KEO 919-000-811 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 supply genuine KEO tooling to industrial buyers globally.

How to select the right KEO countersink for your application?

To select the right KEO countersink, match the angle (e.g., 100°) to your fastener's head angle, and choose body diameter (e.g., 1/2 in) based on hole size. For harder materials, opt for cobalt steel like the 919-000-811. Six-flute designs reduce chatter for smoother finishes in production runs.
