Product Description

KEO Fast-Cutting Single-Flute Countersinks.

Frequently Asked Questions

What is a KEO 90° countersink used for?

A KEO 90° countersink creates a conical recess for flathead screws or deburrs holes in metal. This single-flute, cobalt model is designed for fast cutting in hard materials like stainless steel, delivering a clean finish in machining and fabrication applications.

What are the specifications of the KEO 919-000-603 countersink?

The KEO 919-000-603 is a 90° countersink with 1 flute and a 3/8 in body diameter. It is made from cobalt steel for heat resistance and durability. This fast-cutting single-flute design is ideal for high-speed production work on ferrous metals.

Where to buy KEO countersinks worldwide?

3G Electric supplies KEO countersinks like the 919-000-603 to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this cobalt, single-flute tool.

How to select the right KEO countersink for your job?

Match the countersink angle (90° for standard flathead screws) and body diameter to your fastener size. For hard metals, choose cobalt or carbide. Single-flute designs like this KEO model cut faster with less chatter. Always test on scrap material first.
