Product Description

KEO Smooth-Finish Six-Flute Countersinks.

Frequently Asked Questions

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

This KEO countersink is designed for creating smooth, burr-free 120° chamfered holes in metal, ideal for aerospace, automotive, and general machining applications. Its six-flute design provides a finer finish than standard three-flute tools.

What are the specifications of the KEO 919-000-878 countersink?

The KEO 919-000-878 is a 120° countersink with six flutes, a 1/4 in body diameter, and a TiN-coated cobalt construction. The TiN coating reduces friction and extends tool life when machining hard materials.

Where to buy the KEO 919-000-878 countersink worldwide?

You can source the KEO 919-000-878 countersink through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations, ensuring reliable supply for your operations.

How to select the right KEO countersink for your application?

Select based on hole angle (120° for standard countersunk screws), material (TiN-coated cobalt for steel or stainless), and desired finish. Six-flute designs like this KEO model produce smoother surfaces than three-flute versions, ideal for precision work.
