Description

ZANHO TNMA1604 is a high-strength triangular negative turning insert specifically designed for Heavy Rough Machining of Cast Iron. Featuring a robust flat-top design, it provides maximum edge stability and superior impact resistance, ensuring reliable performance in demanding high-production CNC environments.

Cast Iron Roughing Performance

  • Cast Iron Specialist: Specifically engineered for the rough machining of grey cast iron and ductile iron, offering excellent wear resistance against abrasive materials.
  • Flat-Top Design: The TNMA geometry without a chipbreaker provides maximum cutting edge strength, ideal for high-impact and interrupted cutting tasks.
  • Extreme Stability: Optimized for stable performance at large depths of cut (ap up to 4.5mm), significantly increasing metal removal productivity.
  • High Cost-Efficiency: Negative triangular design offers 6 robust cutting edges, delivering a long tool life and consistent results in heavy-duty operations.
