Product Description

KEO Smooth-Finish Six-Flute Countersinks.

Frequently Asked Questions

What is the KEO 6-flute countersink used for?

The KEO 6-flute countersink is used for deburring and countersinking holes in metal, producing a smooth 90° chamfer. It is ideal for aerospace, automotive, and general machining applications where a clean finish is required. The six-flute design reduces chatter and vibration.

What are the specifications of the KEO countersink 919-000-786?

The KEO countersink model 919-000-786 has a 90° included angle, 6 flutes, and a 7/8 in body diameter. It features a TiN (titanium nitride) coating on cobalt steel for extended tool life. This smooth-finish countersink is designed for precision chamfering in ferrous and non-ferrous materials.

Where to buy the KEO 6-flute countersink worldwide?

You can source the KEO 6-flute 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 on this KEO tool.

How to select the right KEO countersink for your application?

Select the KEO countersink based on hole size and material. For a 90° chamfer, match the body diameter to your hole depth. The 6-flute design suits harder materials like stainless steel, while the TiN coating reduces friction. Always use proper cutting speeds and coolant for best results.
