CNMG 120412EL-SI INSERT GRADE T8430

Experience precision and efficiency with the double-sided negative turning insert from Dormer Pramet®. Featuring an 80-degree rhomboid design, an ISO-tolerance class-M indexing accuracy, and chip-breaker SI with rounded cutting edges, this insert excels in medium to heavy machining of steels and stainless steels.

Features and Benefits
• Rounded edges facilitate smooth machining with light feed and shallow depths, ensuring ample edge strength without inducing work-hardening risks
• 2-D chip-breaker guarantees precise chip control, enhancing performance in the application area
• Wide chip groove optimises chip control for tough materials, promoting efficient chip evacuation during machining
• WC-Co substrate, submicron-grained, offers high hardness and resistance to abrasive wear and comb cracks
• PVD coating enhances thermal cracking resistance, ensuring consistent performance even in fluctuating cutting temperatures
• Multi-layered PVD coating, including TiN and AlTiN layers, provides optimized productivity and durability, resisting crater and flank wear
• Unique TiBN top layer reduces build-up edge, enhancing overall performance in various machining scenarios
• A new coating generation ensures heightened durability and performance, making it the most versatile choice for general turning and heavy roughing, even in challenging conditions
