TNGA160412 WXM 255

WXM255 Grade: This grade offers extraordinary wear resistance, setting new standards for shape and dimensional accuracy. Its thermally stable binder phase and low chemical affinity to chrome make it particularly suitable for machining hardened ball bearing steels. The tipped geometry is optimized for light cutting, offering excellent surface finish and dimensional accuracy.
