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?

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.
