Description
The Worldia ManaNova CNGA MHN20C turning insert (CNGA120402-2N) is a premium CBN insert engineered for hardened steel turning. With CNGA rhombic geometry and a durable coating, it’s built for medium interrupted cuts and helps shops extend tool life.
This design eliminates the need for additional grinding, delivering wear resistance and reliable results right from the first pass, which translates to higher throughput and fewer tool changes in demanding turning operations.
- Wear-Resistant Coating for Longer Life: The advanced coating protects the cutting edge under medium interrupted cutting, increasing tool life and reducing replacement frequency.
- CNGA Rhombic Geometry for Stable Cutting: Balanced geometry promotes even contact and predictable performance when turning hardened steel, helping maintain accuracy and finish quality.
- Grind-Free Process for Faster Setup: Eliminates extra grinding steps, saving setup time and speeding up production without sacrificing reliability.
By combining wear resistance, stable geometry, and grind-free setup, the Worldia ManaNova CNGA MHN20C helps you maintain tight tolerances, achieve consistent surface finishes, and improve overall machining efficiency in hardened-steel applications.
