improved strength and wear resistance to carbide
        grades, enabling higher productivity.


        In CVD coatings, due to the difference in thermal
        expansion coefficients between the substrate
        and the coating layers, internal tensile stresses
        are produced. Also, PVD coatings feature
        surface droplets. These factors negatively affect
        a coating and therefore shorten insert tool life.
        Applying SUMOTEC post-coating technologies
        considerably reduces and even removes these
        unwanted defects and results in increasing the
        tool life of the grade and greater productivity.

        Continuous developments in carbide insert
        technology have opened several areas of progress.
        Advanced methods of pressing and sintering,
        coating processes, post-coating treatments, new
        options for surface treatment
        and the optimization of cutting geometry result
        in the manufacturing of indexable inserts that
        meet the machining requirements of today’s
        metalworking industries.

        ISCAR’s recently developed grade IC6025 is intended
        specifically for turning materials related to ISO M
        group (austenitic and duplex stainless steel). The
        grade substrate is a multi-layered coating that features
        post-coated treatment.The grade enabled significant
        improvements in productivity related to turning
        materials in the aerospace industry. (fig.6)
