CNMG120408M XC7120

The CNMG120408M XC7120 is an 80° Rhombic (Diamond) insert featuring 4 cutting edges for maximum economy. Combined with the advanced XC7120 PVD-coated grade, this insert excels at managing the high heat and work-hardening tendencies of stainless steel, ensuring a stable process and extended tool life.

Key Features:

• Grade XC7120: A premium PVD-coated grade with high-density TiAlN layers. It provides exceptional thermal stability and prevents Built-Up Edge (BUE), which is common when machining austenitic stainless steels like 304 and 316.

• Chipbreaker: Specifically designed for Medium (M) machining. The geometry features a reinforced edge and a unique rake angle that ensures smooth chip evacuation and reduces cutting pressure, preventing vibration in slender workpieces.

• 0.8mm Nose Radius: Offers a robust cutting edge capable of handling varied depths of cut. It provides excellent durability for semi-roughing while still delivering a clean surface finish during finishing passes.

• Superior Toughness: The substrate is engineered to resist thermal cracking and mechanical shock, making it ideal for slightly interrupted cuts or varying skin conditions on raw material.

Best For:

• General turning and semi-finishing of all Stainless Steel series (200, 300, and 400).

• High-performance machining of Inconel, Titanium, and Duplex alloys.

• Fits standard DCLNR / PCLNR / MCLNR style tool holders.
