CNMG120408‑MM 1125 Grade Tungsten Carbide Indexable Turning Insert Compatible with Sandviks Coromant For CNC Metal Lathe Turning Machining

CNMG120408-MM 1125 is a high-performance 80° rhombic turning insert belonging to the Coromant T-Max® P series, specifically designed for semi-finishing of steel, stainless steel, and superalloys. Combining advanced PVD TiAlN coating technology with a cemented carbide substrate, it achieves excellent wear resistance and thermal shock resistance while ensuring cutting edge toughness, making it ideal for precision machining requirements in high-end manufacturing sectors such as aerospace and energy equipment.

• Multi-material Machinability:ISO application range covers P15-P45 (steel), M15-M35 (stainless steel), S15-S35 (superalloys), providing a one-stop solution for semi-finishing of various difficult-to-machine materials.
• Superior Wear & Heat Resistance:PVD TiAlN coating maintains stable hardness at temperatures above 500°C, increasing crater wear resistance by 30% compared to traditional coatings and extending tool life.
• Optimized Chip Control:MM chip breaker design enables efficient chip evacuation through special edge geometry, reducing chip entanglement especially in stainless steel machining and minimizing downtime for chip cleaning.
• Cutting Edge Security:Gradient combination structure of cemented carbide substrate and coating effectively prevents edge chipping under low-speed heavy-load or light interrupted cutting conditions, improving machining stability.

Widely used in aerospace (turbine blades, engine components), energy equipment (wind power shaft parts), construction machinery (hydraulic cylinders) and other fields, especially suitable for semi-finishing of nickel-based superalloys such as Inconel 718 and Hastelloy 276.
