T1000A / T1500A / T1500Z / T2500Z
T1000A : H igh-hardness cermet with outstanding wear resistance and toughness. Creates high dimensional accuracy for continuous steel machining or finishing of powdered metal or cast iron. T1500A : A general-purpose cermet made from hard grains with different grain sizes, delivering functionality that provides an excellent balance of wear resistance and toughness, along with good surface finish quality. T1500Z : Incorporates Brilliant Coat ® PVD coating with excellent lubricity to provide better wear resistance and consistent surface finishes in low-speed cutting applications such as machining of small products or low carbon steel. T2500Z : Features Brilliant Coat ® PVD coating along with optimized substrate for doubling breakage resistance in moderate to interrupted cutting applications.
