DCMT11T304-HM YBD151 Cast Iron Turning Inserts
Product Overview
The DCMT11T304-HM YBD151 is a specialized 55° rhombic positive insert purpose-built for Cast Iron (K-Class). By integrating the YBD151 Grade—a high-strength substrate paired with a multi-layer CVD coating—this insert excels in high-speed dry cutting and high-temperature environments. The -HM (Medium-Duty) chipbreaker is engineered with a unique land and rake angle that prevents edge chipping while ensuring consistent chip breaking in abrasive materials.
Key Advantages
- ✔ YBD151 Performance Grade: Optimized for K10–K25 materials, offering extreme abrasive wear resistance and high thermal stability.
- ✔ -HM Chipbreaker: Designed for medium-duty turning, balancing edge strength with efficient chip evacuation in cast materials.
- ✔ Advanced CVD Multi-Layer: Reduces friction and prevents built-up edge (BUE) during high-velocity cutting.
- ✔ Stable Edge Geometry: Peripheral grinding ensures high repeatability and minimal vibration.

Customer Feedback
⭐⭐⭐⭐⭐
"Perfect for Brake Rotors"
We switched to YBD151 for HT250 gray iron. Tool life increased by 30% over our previous Japanese supplier.
— John M., USA⭐⭐⭐⭐⭐
"Super Standzeit"
Consistent quality and very high cutting speeds possible. Excellent finish on ductile iron parts.
— Klaus R., Germany⭐⭐⭐⭐
"Ottimo rapporto qualità-prezzo"
Dependable for semi-finishing. The -HM breaker is very versatile for different cast iron grades.
— Roberto L., Italy⭐⭐⭐⭐⭐
"鋳物加工の定番"
Stable machining performance in heavy production runs. Highly recommended for CNC lathes.
— Tanaka Y., JapanFrequently Asked Questions
A: Yes, but it is optimized for high-speed dry cutting in gray iron. If you use coolant, ensure it is high volume and consistent to avoid thermal cracking.
A: -HM is for medium-duty semi-finishing to finishing, whereas -HR is designed for roughing with heavier chip loads.
A: Yes, as long as the holder is designed for the 11T3 (3/8" IC) size, such as the SDJCR or SDUCR series.
Material Comparison Tip: For high-speed machining of Gray Cast Iron, YBD151 is your first choice due to its extreme hardness. However, if you are machining Ductile Iron (Nodular) with heavy interruptions, the YBD252 provides better edge toughness to prevent fracturing.
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.
