DCMT11T308-HM YBD151 Cast Iron Turning Inserts
Product Overview
The DCMT11T308-HM YBD151 is a premier 55° rhombic positive insert designed specifically for Cast Iron (K-Class). By utilizing the YBD151 Grade—featuring a high-strength substrate with a thick CVD coating—this insert provides unmatched wear resistance in abrasive cast materials. The -HM (Medium-Duty) chipbreaker is engineered to balance edge strength with efficient chip evacuation, making it the ideal choice for high-productivity CNC operations.
Key Performance Advantages
- ✔ YBD151 Coating Technology: Optimized for K10–K25 range, providing extreme thermal stability and resistance to abrasive wear.
- ✔ -HM Chipbreaker Logic: Designed for stable medium-duty machining with a reinforced rake angle to prevent edge chipping.
- ✔ Reinforced 0.8mm Radius: The 308 geometry offers a stronger edge than the 304, allowing for higher feed rates and better durability.
- ✔ High-Speed Finishing: Allows for significantly higher surface speeds (Vc) without compromising tool life.

Customer Feedback
⭐⭐⭐⭐⭐
"Excellent in Gray Iron"
The 0.8mm radius is much stronger. We've seen a 25% increase in tool life over our previous supplier.
— Michael R., USA⭐⭐⭐⭐⭐
"Sehr Gut"
Consistent quality. The YBD151 grade handles high temperatures without losing the edge.
— Klaus F., Germany⭐⭐⭐⭐
"Reliable Performance"
Great for ductile iron. Chip control is consistent across different feed rates.
— Hiroshi T., Japan⭐⭐⭐⭐⭐
"Top quality"
Highly recommended for anyone machining automotive cast iron parts.
— Fabio L., ItalyFrequently Asked Questions
A: YBD151 is a hard grade optimized for continuous cutting. For heavy interruptions, we recommend switching to YBD252.
A: No. YBD151 is a K-Class grade (Cast Iron). For Stainless Steel, please use the YBM series.
A: The 0.8mm radius (308) provides a stronger cutting edge and allows for higher feed rates, though it requires more machine rigidity.
Material Comparison Tip: When machining Gray Cast Iron at high speeds, YBD151 is the primary choice due to its high abrasive wear resistance. If you experience edge chipping due to vibration, consider dropping the cutting speed or switching to a tougher substrate.
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.
