EXOCARB® WXS® (While Supplies Last!) (4430)

Premium High Performance Carbide End Mills for Hardened Steels

While Supplies Last


EXOCARB®-WXS end mills are the new industry standard for hard milling. Everything about WXS is designed for rigidity and performance in hardened steel 50 HRC and greater. Substrates, geometry, and proprietary WXS coating are all specifically tailored for hardened steels like D2, A2, S7, H13 and CPM.

While Supplies Last!

We are currently in the process of phasing out and discontinuing List #4410 WXS-EBM-(Inch). Limited quantities continue to be available while supplies last, check stock by item on the product offering page.

List #4430 will be replaced with #8430 AE-BM-H (Inch),the full crossover file can be found here.


Ultra-fine micrograin carbide

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

High Precision geometry - All corner radius & ball 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.

WXS coating - +1300 Celsius Oxidation Temp. & +3500Hv in hardness

Higher coating oxidation temp & hardness dramatically improve wear resistance.
