Product Description

KEO Fast-Cutting Single-Flute Countersinks.

Frequently Asked Questions

What is a KEO 82° countersink used for?

A KEO 82° single-flute countersink creates a conical recess for flat-head screws in metal. The 82° angle matches standard US fastener heads, and the TiN-coated cobalt construction handles hardened steels and abrasive materials in machining and fabrication.

What are the specifications of the KEO 919-000-578 countersink?

The KEO 919-000-578 is an 82° single-flute countersink with a 1/4 in body diameter. It features a TiN coating on cobalt steel for heat resistance and wear life. This fast-cutting design suits production deburring and countersinking in ferrous metals.

Where to buy KEO countersinks worldwide?

3G Electric supplies KEO countersinks like the 919-000-578 to global buyers. We handle full logistics, customs clearance, and delivery worldwide. Contact us for pricing and lead time on this TiN-coated cobalt tool.

How to select the right KEO countersink for my application?

Match the countersink angle to your screw head — 82° for US flat-head screws. Choose a single flute for fast chip removal in softer metals, or multi-flute for smoother finish in harder alloys. TiN coating extends tool life in abrasive materials like stainless steel.
