Frequently Asked Questions

What is a KEO 110° countersink used for?

A KEO 110° countersink creates a smooth, chamfered recess for flat-head screws in metalworking. Its six-flute design and TiN-coated cobalt construction deliver a fine finish in steel, stainless, and alloys. 3G Electric supplies this tool across 14 industrial departments, including machining and instrumentation.

What are the specifications of the KEO 55581-TiN countersink?

The KEO 55581-TiN is a 110°, six-flute countersink with a 3/16 in body diameter and 3/16 in shank. It is made of TiN-coated cobalt for heat resistance and extended tool life. This smooth-finish design is ideal for precision chamfering in production environments.

Where to buy KEO countersinks worldwide?

How to select the right KEO countersink for metal?

Match the countersink angle to your fastener (e.g., 110° for sheet metal screws). Choose flute count based on finish: six flutes reduce chatter for smoother results. TiN coating suits harder materials like stainless steel. 3G Electric can help interpret your application and source the correct KEO tool.
