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 deburring and countersinking holes in industrial manufacturing.

What are the specifications of the KEO 919-000-153 countersink?

The KEO 919-000-153 is a 120° countersink with a single flute and a 3/4 in body diameter, made from high-speed steel. It is designed for fast cutting and is suitable for use in drill presses and handheld tools. The part number is 919-000-153, and it is manufactured by KEO.

Where to buy the KEO 919-000-153 countersink worldwide?

You can source the KEO 919-000-153 countersink through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations, ensuring you receive the correct KEO tool for your machining needs.

How to select the right KEO countersink for your application?

To select the right KEO countersink, match the body diameter and angle to your fastener requirements. For flat-head screws, a 120° angle is standard. Consider material hardness and choose high-speed steel for general use. Ensure the flute count suits your speed and finish needs; single-flute designs offer fast chip removal.
