ZCC.CT TCMT16T308-HM YBM351 Turning Insert
Toughness-Oriented CVD Solution for Stainless Steel (ISO M) Machining
Product Overview
"Which carbide insert is most reliable for interrupted cuts and medium-roughing of stainless steel under unstable conditions?"
The ZCC.CT TCMT16T308-HM YBM351 is a high-toughness triangular turning insert designed for demanding ISO M (Stainless Steel) applications. The YBM351 grade utilizes a thick CVD coating combined with a high-strength substrate to resist notch wear and thermal cracking. Paired with the -HM chipbreaker, this insert excels in medium-duty machining where chip control and edge security are critical.

Industrial Real-World Feedback
"Unstoppable on Duplex"
The YBM351 is my go-to for 316 and Duplex 2205. The edge doesn't chip even during heavy interruptions.
— Robert J., USA 🇺🇸"Perfekt für V4A"
Sehr gute Standzeit bei Edelstahl. Der HM-Spanbrecher funktioniert hervorragend.
— Dieter S., Germany 🇩🇪"Reliable Performance"
Good tool life in unstable setups. Great cost-to-performance ratio for stainless steel valve bodies.
— Marco G., Italy 🇮🇹Expert Technical Support
Q: Why is YBM351 better for stainless steel than YBC grades?
A: YBM351 is specifically optimized for the low thermal conductivity and work-hardening properties of stainless steel, whereas YBC grades are tuned for carbon steel hardness.
Q: Can I use this for finishing?
A: The -HM chipbreaker is designed for medium-heavy cuts. For fine finishing, we recommend the -HF or -EM geometry.
Q: What coolant strategy is best?
A: High-pressure emulsion coolant is highly recommended to prevent heat buildup and improve chip evacuation in austenitic alloys.
Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
