CNMG120408R XC8120

The CNMG120408R XC8120 features a robust 80° rhombic shape with 4 usable cutting edges, making it a highly economical choice for CNC production. Paired with the XC8120 grade, it is designed to conquer the abrasive wear challenges of grey and ductile iron, providing a stable cutting edge that resists cratering even at high temperatures.

Key Features:

• Grade XC8120: A premium CVD-coated grade featuring a thick, wear-resistant coating. It is specifically optimized for Cast Iron (K) applications, ensuring that the tool maintains its geometry despite the highly abrasive nature of cast iron skins and inclusions.

• 0.8mm Nose Radius: Provides a significantly stronger cutting edge than the 0.4mm version. It allows for higher feed rates and provides better durability when facing "crusty" cast surfaces or interrupted cuts.

• CVD Multi-Layer Coating: The advanced coating technology acts as a thermal barrier, allowing for increased cutting speeds and reducing the risk of thermal cracking during long production runs.

• Double-Sided Economy: With 4 true cutting edges, this negative geometry insert offers a lower cost-per-component compared to positive inserts, without sacrificing metal removal rates.

Best For:

• Medium-duty roughing and semi-finishing of Grey Cast Iron (GG) and Ductile Iron (GGG).

• High-production environments where tool life predictability is essential.

• Fits all standard DCLNR / PCLNR / MCLNR style external tool holders and boring bars.
