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 steel, aluminum, and other materials, making it ideal for deburring and countersinking holes in industrial manufacturing.

What are the specifications of the KEO 919-000-057 countersink?

The KEO 919-000-057 is a 120° countersink with 1 flute and a 1-inch body diameter, made from high-speed steel. It is designed for fast cutting and produces a smooth finish. The single-flute geometry reduces vibration, and the 120° angle matches standard flat-head screw angles for precise seating.

Where to buy KEO countersinks worldwide?

You can source KEO countersinks like the 919-000-057 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 times on this and other KEO cutting tools.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the screw head angle (e.g., 120° for flat-head screws), material (high-speed steel for general use), and body diameter matching the screw head size. For deburring, a single-flute design reduces chatter. Always match the countersink angle to the screw's included angle for proper seating.
