Frequently Asked Questions

What is the KEO 120° countersink used for?

The KEO 120° countersink is used to create a conical recess for flat-head screws in metalworking and machining applications. Its single-flute design provides fast, chatter-free cutting in materials like steel and aluminum, making it ideal for precision deburring and countersinking in industrial manufacturing.

What are the specifications of the KEO 919-000-166 countersink?

The KEO 919-000-166 is a 120° countersink with 1 flute and a 3/8 in body diameter. It features a TiN coated high speed steel construction for extended tool life and reduced friction. This fast-cutting single-flute countersink is designed for efficient material removal in metalworking.

Where to buy the KEO 919-000-166 countersink worldwide?

You can source the KEO 919-000-166 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 the KEO countersink based on the screw head angle (120° for flat-head screws), material hardness (TiN coated HSS for ferrous metals), and body diameter matching the screw head size. For optimal results, match the flute count to your material—single-flute designs reduce chatter in softer metals.
