Frequently Asked Questions

What is the KEO 55450-TiN countersink used for?

The KEO 55450-TiN is a fast-cutting single-flute countersink designed for deburring and chamfering holes in metal. Its 110° included angle and TiN-coated cobalt construction suit hardened steels and alloys, providing extended tool life in industrial machining and fabrication applications.

What are the specifications of the KEO 55450-TiN countersink?

The KEO 55450-TiN has a 1/4 in body diameter, 110° included angle, and one flute. It is made from TiN-coated cobalt steel. The manufacturer part number is 55450-TiN, and it is classified as a fast-cutting single-flute countersink for precision chamfering.

Where to buy the KEO 55450-TiN countersink worldwide?

3G Electric supplies the KEO 55450-TiN countersink worldwide. As a global industrial equipment distributor since 1990, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on this single-flute countersink.

How to select the right KEO countersink for my application?

Select a KEO countersink based on material hardness and hole size. The 55450-TiN with 110° angle and TiN coating is ideal for hardened steels. Match the body diameter to your hole chamfer requirement. For softer materials, consider uncoated HSS variants. Always verify shank compatibility with your tool holder.
