ZCC.CT DNMG150408-PM YBC151 Carbide Inserts
Product Overview
The DNMG150408-PM YBC151 is a high-performance 55° rhombic negative insert optimized for Steel (P-Class) machining. Featuring the YBC151 grade—a combination of a thick Al2O3 and TiN CVD coating on a high-speed substrate—it offers exceptional wear resistance and thermal stability. The -PM (Semi-Finishing to Medium) chipbreaker is engineered for versatile chip control, preventing "birds-nesting" during long-cut cycles in mild and alloy steels.
Core Technical Advantages
- ✔ YBC151 High-Speed Grade: Optimized for P05–P20 steel applications with extreme resistance to crater wear.
- ✔ -PM Chipbreaker Geometry: A dual-angle rake design that reduces cutting forces while ensuring stable chip breaking.
- ✔ Thick CVD Coating: Provides a massive thermal barrier for high-speed dry or wet machining.
- ✔ Precision 0.8mm Radius: Offers enhanced edge strength and superior surface finishes at higher feed rates.

— Luca V., Italy 🇮🇹Frequently Asked Questions
Q: Can I use this for stainless steel?
A: While it can cut stainless in a pinch, YBC151 is a P-grade (Steel). For Stainless Steel, we highly recommend the YBM series.
Q: What is the benefit of the PM chipbreaker?
A: It is a general-purpose medium-duty breaker that offers a wide application range between finishing and roughing.
Q: Is coolant necessary?
A: Yes, using coolant is recommended to maximize the life of the CVD coating, especially at higher speeds.
Industrial Tip: YBC151 is your go-to for speed. If you experience edge chipping due to vibration or interrupted cuts, consider switching to YBC251 for increased 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.
