CCMT Turning Insert, 80° Rhombus, Grade T8430

Experience precision machining with the single-sided positive turning insert from Dormer Pramet®. This tool ensures reliable indexing thanks to the eighty-degree rhomboid design, seven-degree clearance, and ISO-tolerance class-M accuracy. The NF2 chip-breaker with rounded edges enhances chip control, making it ideal for fine to medium machining of stainless steels.

Features and Benefits
• Shallow chip groove for efficient chip breaking across diverse cutting feeds
• WC-Co substrate with submicron graining offers high hardness, abrasive wear resistance, and comb crack resistance
• PVD coating enhances thermal cracking resistance and overall performance in fluctuating cutting temperatures
• Multi-layered coating for increased productivity, featuring thick TiN for crater wear resistance, hard AlTiN for flank wear resistance, and unique TiBN top layer for reduced build-up edge
• Rounded edges without T-land enable smooth machining with light feed and shallow depths of cut, ensuring sufficient edge strength and minimizing work-hardening risk
• 2-D chip-breaker guarantees precise chip control at the application area

Typical Applications
• Stainless steel
• General engineering applications
