DNMG150608-PM YBD252: High-Stability Cast Iron Turning
Product Overview
The DNMG150608-PM YBD252 is an industrial-grade turning solution specifically designed for the Cast Iron (K-Class) family. The YBD252 grade features a specialized thick CVD coating that offers superior resistance to abrasive wear and thermal cracking. Paired with the -PM (Semi-Finishing to Medium) chipbreaker, this insert delivers exceptional stability and chip control in materials like Ductile Iron (FCD) and Grey Iron (FC).
Key Performance Advantages
- ✔ YBD252 Technology: Advanced CVD coating with Al2O3 and TiCN layers provides high hardness and heat resistance at the cutting zone.
- ✔ -PM Geometry: A versatile chipbreaker that balances edge strength with sharp cutting action, ideal for cast iron's brittle chip nature.
- ✔ Abrasive Resistance: Specifically formulated substrate to prevent flank wear caused by the high carbon/silicon content in cast iron.

Stable at 300 m/min. The finish is excellent for a PM breaker.
— Sato M., Japan 🇯🇵⭐⭐⭐⭐
"Qualità costante"
Great balance between cost and tool life. Minimal edge chipping.
— Paolo C., Italy 🇮🇹Frequently Asked Questions
Q: Why use YBD252 instead of a general steel grade?
A: Cast iron contains high amounts of silicon and carbon, which are highly abrasive. YBD252 has a coating thickness and substrate toughness designed specifically to combat this abrasive wear, which would quickly destroy a steel grade insert.
Q: What is the optimal coolant setup for this insert?
A: While YBD252 handles dry machining well on grey iron, using high-pressure coolant on ductile iron can significantly improve tool life and surface finish.
Q: Is this original ZCC.CT?
A: Yes, we are an authorized distributor. All inserts come in original factory-sealed 10-piece packaging with QR code verification.
Material Selection Tip: For Grey Cast Iron (GG) with stable cuts, you can increase speed up to 400 m/min. For Ductile Iron (GGG), maintain a more conservative feed rate to protect the nose radius.
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.
