DCMT11T304-HM YBC151 Turning Inserts
Product Overview
The DCMT11T304-HM YBC151 is a high-performance 55° rhombic positive insert designed for Steel (P-Class) machining. Utilizing the YBC151 Grade—a thick Al2O3 and TiCN CVD coating—this insert is optimized for high-speed operations where heat resistance and wear resistance are paramount. The -HM (Medium-Duty) chipbreaker geometry provides a versatile range of chip control, ensuring smooth evacuation even at varying depths of cut, making it the industry standard for semi-finishing to finishing applications.
Key Technical Features
- ✔ YBC151 High-Stability Grade: Specifically designed for P05–P20 applications, offering superior crater wear resistance at high temperatures.
- ✔ -HM Chipbreaker Geometry: A reinforced cutting edge combined with a wide chip-breaking range to handle medium-duty finishing.
- ✔ Enhanced CVD Coating: Thick Al2O3 layer ensures tool longevity during long-run high-speed continuous cutting.
- ✔ Positive Rake Angle: Reduces vibration and cutting resistance, perfect for internal boring and high-precision external turning.

Customer Feedback
"Excellent for long runs"
Running these at 300 m/min in 1045 steel. Tool life is consistent and finish is superb. Better than more expensive German brands.
— Robert K., Germany"Great chip control"
The -HM breaker handles variations in depth of cut very well. No more bird nesting on my CNC lathe.
— David L., USA"Versatile finishing"
Molto buono. Used for internal boring. Very stable and low vibration.
— Giorgio M., ItalyFrequently Asked Questions
A: While it can cut stainless, YBC151 is optimized for Steel (P). For Stainless, we recommend the YBM series for better thermal management.
A: -HM is best for semi-finishing to finishing. For heavy roughing, the -HR breaker is more appropriate to handle larger chip loads.
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.
