DCGT 11T308ER-SI Insert Grade T8430

Revolutionise precision machining with the single-sided positive turning insert from Dormer Pramet. The 55-degree rhomboid design features a 7-degree clearance, specifically tailored for left-handed turning tools. Crafted from grade T8430 and PVD-coated, the fine-grained WC-Co carbide operates within ISO ranges P20-P40 and M20-M35 to ensure optimal cutting performance and extended tool life. Features and Benefits Multi-layered PVD coating for increased productivity and durability Unique TiBN top layer reduces build-up edge, improving overall performance Rounded edges without T-land enable smooth machining with light feed and shallow depths, balancing edge strength and preventing work-hardening 3-D chip-breaker ensures precise control at various feeds and depths of cut WC-Co-based substrate, submicron-grained, provides high hardness and resistance against abrasive wear and comb cracks PVD coating enhances thermal cracking resistance and performance in operations with cutting temperature fluctuations Typical Applications Steel Stainless steel Automotive Aerospace Fine to medium machining
