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 design and AlTiN-coated carbide body provide fast, clean cutting in hardened steels and alloys, common in aerospace and automotive manufacturing.

What are the specifications of the KEO 919-002-355 countersink?

The KEO 919-002-355 is a 100° single-flute countersink with a 1/4 in body diameter. It features AlTiN-coated carbide construction for heat resistance and extended tool life. The 100° angle suits metric flat-head fasteners used in precision machining.

Where to buy KEO countersinks worldwide?

3G Electric supplies KEO countersinks like the 919-002-355 to global customers. We handle full logistics, customs clearance, and delivery worldwide. Contact us for pricing and lead time on this AlTiN-coated carbide tool.

How to select the right KEO countersink for your application?

Match the countersink angle to your fastener head (100° for metric flat-head screws). Choose AlTiN coating for high-temperature alloys or uncoated carbide for softer materials. Single-flute designs like KEO’s offer faster chip evacuation in production runs.
