Share :
The CNMG120404F XC8120 is an 80° Rhombic (Diamond) insert that offers high edge strength and economy with 4 cutting edges. Featuring the XC8120 grade, this insert is engineered to withstand the abrasive nature of Cast Iron, providing exceptional wear resistance and preventing premature edge failure.
Key Features:
Grade XC8120: A specialized CVD-coated grade optimized for Cast Iron (K). It features a thick, hard coating that resists the abrasive wear typical of grey and ductile iron, allowing for stable machining even at high temperatures.
0.4mm Nose Radius: Precision-ground for finishing and semi-finishing tasks. The smaller radius reduces cutting forces and is perfect for achieving tight tolerances and superior surface finishes on cast components.
Negative Geometry: The double-sided design provides 4 usable cutting edges, offering a significantly lower cost-per-edge for high-production machine shops.
Robust Chip Control: Unlike flat-top inserts, this CNMG geometry helps manage chips during variable depths of cut, ensuring they don't mar the finished surface of the workpiece.
Best For:
Finishing and semi-finishing of Grey Cast Iron and Ductile/Nodular Iron.
High-volume production where tool life consistency is critical.
Compatible with standard DCLNR / PCLNR / MCLNR style tool holders.
