Frequently Asked Questions

What is a KEO 100° countersink used for?

A KEO 100° countersink creates a conical recess for flat-head screws in metalworking. Its single-flute, cobalt design cuts fast and resists heat, making it ideal for production machining, tool-and-die work, and maintenance applications across industrial departments.

What are the specifications of the KEO 919-000-627 countersink?

The KEO 919-000-627 is a 100°, single-flute countersink with a 3/8 in body diameter, made from cobalt steel. It is designed for fast cutting in hard materials and is commonly used in drill presses and CNC machines for precision chamfering.

Where to buy KEO countersinks worldwide?

3G Electric supplies KEO countersinks like the 919-000-627 to customers worldwide. We handle full logistics, customs clearance, and delivery, ensuring you receive the correct cutting tool for your application, regardless of your location.

How to select the right KEO countersink for my job?

Match the countersink angle (e.g., 100°) to your screw head, and choose body diameter (3/8 in) to suit hole size. For hard metals, select cobalt steel like the KEO 919-000-627. Single-flute designs offer faster chip evacuation in production runs.
