Product Description

KEO Smooth-Finish Six-Flute Countersinks.

Frequently Asked Questions

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

The KEO 120° 6-flute countersink is designed for creating smooth, burr-free 120° chamfers on drilled holes in metal, plastic, and wood. Its six-flute geometry reduces chatter and vibration, making it ideal for precision deburring and countersinking in automotive, aerospace, and general manufacturing applications.

What are the specifications of the KEO 919-002-673 countersink?

The KEO 919-002-673 is a 120° countersink with six flutes, a 5/16 in body diameter, and an AlTiN-coated high-speed steel construction. The AlTiN coating enhances wear resistance and heat dissipation for longer tool life. It is manufactured by KEO and is suitable for use on ferrous and non-ferrous materials.

Where to buy the KEO 919-002-673 countersink worldwide?

You can source the KEO 919-002-673 countersink 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; we provide reliable sourcing for KEO cutting tools.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the required chamfer angle (e.g., 120°), material type, and hole size. For hard metals, choose AlTiN-coated high-speed steel tools like the 919-002-673 for extended life. Match the body diameter to your hole size and ensure the flute count suits your finish requirements—six flutes reduce chatter for smoother results.
