IMCO Variable Helix End Mill Carbide AlCrN Ball Nose Ball Standard Flute Flutes 4 Single End Pow-R-Feed Mill Carbide As the name suggests, Aluminum Chromium Nitride is a chromium-based coating that was developed in the early part of the 2000’s. Since then, it has been found to be an excellent choice for coating machining tools based on its superior performance in just about every category that matters. This is due in part to the way the chromium atoms interact with the aluminum in the substance, forming a tough layer that gets even stronger as you add more chromium to the mix. The result is a light, silver-grey substance that contains some remarkable properties.
