Frequently Asked Questions

What is the KEO 100° countersink used for?

The KEO 100° countersink is used for deburring and countersinking holes in metal, particularly for 100-degree flat-head screws. Its three-flute design provides smooth cutting and reduced chatter, making it suitable for general-purpose machining in automotive, aerospace, and fabrication industries.

What are the specifications of the KEO 919-002-777 countersink?

The KEO 919-002-777 is a 100°, three-flute countersink with a 3/8 in body diameter. It features an AlTiN coating on cobalt steel for heat resistance and extended tool life. This general-purpose tool is designed for countersinking and deburring in ferrous and non-ferrous materials.

Where to buy the KEO 919-002-777 countersink worldwide?

You can source the KEO 919-002-777 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 on this KEO tool.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the screw head angle (e.g., 100°), material type, and hole size. For hard metals, choose AlTiN-coated cobalt tools like the 919-002-777 for durability. Match the body diameter to your workpiece and ensure proper RPM for clean, chatter-free results.
