DCMT11T308-HR YBD151 Turning Inserts for Cast Iron
Product Overview
The DCMT11T308-HR YBD151 is a 55° rhombic positive insert engineered specifically for Cast Iron (K-Class) machining. By integrating the YBD151 Grade—a high-strength substrate paired with a thick Al2O3 CVD coating—this insert excels in high-speed applications by resisting abrasive wear. The -HR (Heavy Roughing) chipbreaker features a reinforced cutting edge and a wider landing, specifically designed to handle large depths of cut and heavy feed rates while maintaining stable chip breaking in porous cast materials.
Key Performance Advantages
- ✔ YBD151 Advanced Coating: Optimized for K10–K25 range, providing extreme resistance to thermal shock and abrasive wear.
- ✔ -HR Roughing Geometry: Reinforced edge strength prevents chipping during heavy-duty and slightly interrupted cuts.
- ✔ High-Speed Productivity: Designed to run at higher surface speeds (Vc) compared to universal grades, shortening cycle times.
- ✔ 0.8mm Radius Durability: The 308 radius offers a robust tip profile, ideal for heavy metal removal rates (MRR).

⭐⭐⭐⭐⭐
"Perfect for brake discs"
The -HR breaker handles the scale on the casting beautifully. Long life.
— Mike S., USA 🇺🇸⭐⭐⭐⭐⭐
"Exzellente Standzeit"
Running at 300m/min in GG25 without issues. Highly recommended.
— Hans W., Germany 🇩🇪⭐⭐⭐⭐
"Consistent performance"
Reliable inserts for our automated production line in Japan.
— Sato T., Japan 🇯🇵⭐⭐⭐⭐⭐
"Ottima qualità"
The best price-to-performance ratio for ductile iron roughing.
— Fabio L., Italy 🇮🇹Frequently Asked Questions
Q: Can I use this for Stainless Steel?
A: No. YBD151 is a K-Class grade (Cast Iron). For Stainless, use the YBM series.
Q: What is the benefit of the -HR breaker?
A: The -HR is a "Heavy Roughing" breaker. It has a stronger edge than finishing breakers, allowing for deeper cuts without edge chipping.
Q: Is this suitable for dry cutting?
A: Yes. The thick Al2O3 coating on YBD151 provides excellent thermal protection for dry machining of cast iron.
Material Comparison Tip: When machining Gray Cast Iron at ultra-high speeds, YBD151 is your primary choice. If you face heavy interruptions or uneven casting surfaces, consider shifting to YBD252 for increased impact toughness.
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.
