Frequently Asked Questions

What is a KEO 90° single-flute countersink used for?

This KEO countersink creates a 90° chamfer around a pre-drilled hole, allowing screw heads to sit flush with the workpiece surface. It is commonly used in metalworking, machining, and fabrication for deburring and countersinking operations on steel, aluminum, and other materials.

What are the specifications of the KEO 919-000-601 countersink?

The KEO 919-000-601 is a 90° single-flute countersink with a 1/4 in body diameter, made from cobalt steel for heat resistance and durability. It is designed for fast cutting and clean finishes in industrial machining applications. 3G Electric supplies this KEO tool worldwide.

Where to buy KEO countersink 919-000-601 worldwide?

3G Electric supplies the KEO 919-000-601 countersink to customers worldwide. As a global industrial sourcing partner, we handle logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this cobalt single-flute countersink.

How to select the correct KEO countersink for a job?

Match the countersink angle (90° for standard flat-head screws) and body diameter to your fastener size. For hard materials like stainless steel, choose cobalt or carbide. Single-flute designs like this KEO model offer fast chip removal. 3G Electric can help you select the right tool for your application.
