TiCN Coating, formally known as Titanium Carbo-Nitride coating, is an all-purpose strengthening coating that does especially well with cutting applications. Adding a total thickness of approximately .0001″ – .0002″ (2 – 5 Microns), TiCN coating will lengthen the life of your reamer and keep your tools sharper for longer.
