ZCC.CT CCMT09T304-HM YBM151: High-Speed Stainless Steel Precision
Product Overview
The ZCC.CT CCMT09T304-HM YBM151 is a premium industrial grade insert engineered specifically for the M-group (Stainless Steel). The YBM151 grade utilizes a thin, high-density CVD coating coupled with a fine-grained substrate, providing extreme wear resistance at elevated cutting speeds. Combined with the HM (Medium-Finishing) chipbreaker, it effectively manages long, stringy stainless steel chips, preventing workpiece scratching and ensuring high dimensional accuracy.
Key Features
- YBM151 High-Speed Grade: Optimized for finishing to semi-finishing at high velocities with minimal thermal deformation.
- HM Precision Geometry: A stable cutting edge that balances sharpness and strength to minimize built-up edge (BUE).
- Superior Surface Finish: The 0.4mm (0.016") nose radius is designed for low cutting forces and ultra-smooth finishes.
- Advanced CVD Coating: Provides a hard barrier against chemical wear and notch wear, common in austenitic stainless steels.

Frequently Asked Questions
Q: Can I use this for titanium machining?
A: While optimized for stainless steel, YBM151 can handle some titanium alloys at lower speeds. For dedicated titanium work, we recommend the YBS series.
Q: What is the main benefit of the HM chipbreaker?
A: It is designed for medium-finishing, providing a stable cutting edge that excels in chip evacuation for stainless steel to prevent tool failure.
Q: Is it suitable for dry machining?
A: For stainless steel, we always recommend high-pressure coolant to prevent work hardening and extend the life of the YBM151 coating.
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.
