EXOCARB® WXL® (3790)

Premium High Performance Carbide Ball Mills for Pre-hardened & Hardened Steels


EXOCARB® WXL end mills are the new industry standard for hard milling. Everything about WXL is designed for rigidity and performance in wide variety of materials and a wide variety of milling applications. Substrates, geometry, and proprietary WXL coating are all specifically tailored for nonferrous materials, mild steels, and steels up to 50HRC.


Ultra-fine micrograin carbide

The hardest ost wear resistant carbide possible for incredible wear resistance.

High Precision geometry - Ball End Mills have +/-5um radius tolerance

High accuracy all but eliminates need for benching and rework for mold makers.

High strength core diameter

Tools utilize thicker core diameters for the ultimate in strength and rigidity.

WXL coating - +1100 Celsius Oxidation Temp. & +3100Hv in hardness

Higher coating oxidation temp & hardness dramatically improve wear resistance.
