DNMG 110408ER-SI Insert Grade T8430

Experience unmatched precision and efficiency with the double-sided negative turning insert from Dormer Pramet. Tailored for medium to heavy machining of steels and stainless steels, the 55-degree rhomboid design and ISO-tolerance class-M indexing accuracy ensure reliability in diverse applications. Compatible with left-handed turning tools, this insert stands out for its versatility, making it essential for engineering industries. Features and Benefits Raised chip-breaker back wall height compels tighter chip curls, enabling effective machining of tough materials with lower feeds WC-Co-based substrate, submicron-grained, provides superior hardness and resistance against abrasive wear and comb cracks PVD coating enhances thermal cracking resistance and excels in operations with cutting temperature fluctuations Multi-layered PVD coating optimised for increased productivity and durability, featuring a thick TiN coating for crater wear resistance and a hard AlTiN layer for flank wear resistance Unique Titanium-Boron-Nitride (TiBN) top layer reduces build-up edge, enhancing overall performance grade for general turning and heavy roughing, even in challenging conditions Rounded edges without T-land facilitate smooth machining with light feed and shallow depths, delivering ample edge strength while mitigating work-hardening risks 2-D chip breaker ensures precise chip control at the application area Typical Applications Steel Stainless steel Automotive Aerospace
