Chipbreaker and Grade Selection Guide for Turning Material Work Steel Steel Uncoated Cermet Coated Cermet Grades T1000A / T1500A / T1500Z T1000A : High-hardness cermet with outstanding wear resistance and toughness. Realises 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 Insert Grades provides an excellent balance of wear resistance and toughness, along with good surface finish quality. T1500Z : Employs 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. Performance T1000A A ● Wear Resistance Exhibits excellent ● Fracture Resistance Provides excellent fracture and wear resistance. 0.20 Steel wear resistance.
