Tungaloy RCMT0602MO-61 NS9530 Insert
Precision Round Turning | 61 Finishing Breaker | Premium NS9530 Cermet
How can I achieve a mirror-like finish on carbon steel parts?
The Tungaloy RCMT0602MO-61 NS9530 is a high-performance round cermet turning insert engineered for precision finishing operations. Utilizing the advanced NS9530 cermet grade, this insert offers exceptional chemical stability and oxidation resistance, which prevents material welding and ensures an ultra-smooth surface finish. The 61 chipbreaker is specifically designed for light-duty finishing, providing superior chip control at high speeds. As a genuine Japan-made CNC turning insert, the RCMT round geometry offers the strongest cutting edge for profiling and multi-directional turning.
Mirror Finish Quality
NS9530 cermet grade minimizes friction, ensuring a superior surface Ra finish compared to standard carbide grades.
Round Edge Strength
The round geometry provides maximum edge strength, making it ideal for profile turning and variable depths of cut.
61 High-Speed Breaker
Optimized for high-speed finishing (150-350 m/min) while maintaining excellent chip evacuation.

8. FAQ - Common Technical Questions
Q: Is NS9530 better than carbide for stainless steel?
A: Cermet (NS9530) is best for general steel finishing. For stainless steel, we recommend PVD coated carbide like AH725 for better stability.
Q: What is the benefit of a round insert?
A: Round inserts have no weak corner, making them the strongest geometry for high-feed profiling and variable cutting directions.
Q: Does the 61 chipbreaker work for roughing?
A: No, the 61 breaker is specifically for light-duty finishing. For roughing, please check our medium-duty breakers.
Expert Insight: Cermet for Precision Finishing
In CNC turning, cermet (NS9530) provides superior chemical stability over carbide at high temperatures. This prevents the workpiece material from sticking to the tool, ensuring the RCMT0602 delivers a mirror-like shine and tight dimensional tolerances throughout your production run.
