Frequently Asked Questions

What is the KEO 6-flute countersink used for?

The KEO 6-flute countersink is used to create a 90° chamfer or countersink hole in metal, plastic, or wood. Its six-flute design produces a smooth finish and reduces chatter, making it ideal for deburring and preparing holes for flat-head screws in industrial machining and fabrication.

What are the specifications of the KEO countersink 919-000-765?

The KEO countersink model 919-000-765 has a 90° angle, 6 flutes, a 1/8 in body diameter, and a 1/8 in shank. It is made from cobalt steel for durability. This smooth-finish countersink is designed for precision chamfering in metalworking applications.

Where to buy the KEO countersink 919-000-765 worldwide?

You can source the KEO countersink 919-000-765 through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time on this cobalt countersink.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the required chamfer angle (90° for flat-head screws), flute count (6 flutes for smoother finish), and shank size matching your tool holder. For hard materials, choose cobalt steel. Ensure body diameter exceeds the hole size for proper countersinking.
