ZCC.CT CCMT09T308-HM YBC151: High-Performance Steel Turning Insert
Product Overview
"Which insert is best for achieving stable chip control and long tool life during medium-duty turning of carbon and alloy steels at high speeds?"
The ZCC.CT CCMT09T308-HM YBC151 is a premier choice for professionals tackling steel machining (P-group). The YBC151 grade features a thick Al2O3 and TiCN CVD coating, engineered for high-speed continuous cutting where thermal stability is critical. Combined with the HM (Medium) chipbreaker, this insert offers a reinforced cutting edge that balances sharpness with strength, effectively managing chips across various depths of cut to prevent workpiece scratching and tool breakage.
Key Features
- Optimized YBC151 Grade: High wear resistance for continuous high-speed steel turning.
- HM Chipbreaker Geometry: Designed for medium-range machining with excellent chip breaking stability.
- Advanced CVD Coating: Thick multi-layer coating reduces crater wear and enhances heat resistance.
- Robust 0.8mm Radius: Provides a durable edge for higher feed rates and improved surface integrity.

— Robert K., USA
"Perfect Chip Control"
"The HM chipbreaker works perfectly on our automated lines in Germany. No birds-nesting even at medium feeds."
— Lukas M., Germany
"Reliable Performance"
"Running these in Italy for internal boring. The tolerance is stable part after part. Great value."
— Marco B., Italy
"Consistent Quality"
"Our machine shop in Japan relies on ZCC.CT for predictable tool life. YBC151 never disappoints on carbon steel."
— Hiroshi T., Japan
Frequently Asked Questions
Q: Is YBC151 suitable for interrupted cutting?
A: YBC151 is optimized for high-speed continuous cutting. For heavy interrupted cutting, we recommend the tougher YBC251 grade.
Q: Can I use this for stainless steel?
A: While it can cut some ferritic stainless, the YBM series is dedicated to austenitic stainless steel for better anti-sticking performance.
Q: What depth of cut (Ap) is recommended for HM chipbreaker?
A: The HM geometry excels between 1.0mm and 3.5mm depth of cut for optimal chip formation.
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.
