Product Description

KEO Smooth-Finish Six-Flute Countersinks.

Frequently Asked Questions

What is the KEO 100° countersink used for?

The KEO 100° countersink is designed for creating smooth, chamfered holes in metal and composite materials. Its six-flute design and AlTiN coating reduce chatter and extend tool life, making it ideal for aerospace, automotive, and general machining applications where a clean finish is required.

What are the specifications of the KEO 919-002-444 countersink?

The KEO 919-002-444 is a 100° countersink with six flutes, a 3/4 in body diameter, and an AlTiN coated carbide construction. It is manufactured by KEO under part number 919-002-444 and is classified as a Smooth-Finish Six-Flute Countersink for precision deburring and chamfering.

Where to buy KEO countersinks worldwide?

KEO countersinks, including the 919-002-444 model, are available to order through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations, ensuring you receive the correct tool for your machining operations.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the required chamfer angle (e.g., 100°), material type, and desired finish. For hard metals, choose AlTiN coated carbide for heat resistance. Match the body diameter to your hole size and ensure the flute count (six flutes) provides the smooth finish you need.
