DNMG150608-DM YBM351 High-Toughness Turning Inserts
Product Overview
The DNMG150608-DM YBM351 is a specialized industrial insert designed for Stainless Steel (M-Class) and difficult-to-machine materials. The YBM351 grade features a sophisticated CVD coating with high toughness, optimized for M25–M45 applications where edge stability is critical during interrupted cuts. The -DM (Double-sided Medium) chipbreaker is engineered for versatility, offering smooth chip flow and reduced cutting resistance during semi-finishing to medium machining.
Key Performance Features
- ✅ YBM351 Grade: Specifically designed for heavy thermal shock and interrupted cutting in stainless steel.
- ✅ DM Chipbreaker: Balanced rake angle provides a strong edge and prevents chip accumulation (Built-up Edge).
- ✅ 0.8mm Nose Radius: Enhanced edge strength (0.8mm vs 0.4mm) for higher feed rates and structural integrity.
- ✅ 6.35mm Thickness (06): Extra thickness allows for superior heat dissipation and higher mechanical load capacity.

1. Can I use YBM351 on Mild Steel?
While it is possible, YBM351 is optimized for Stainless Steel (M). For Mild Steel (P), the YBC series is more economical and efficient.
2. Why choose -DM over -DF?
-DM is a medium machining breaker for versatility. -DF is specialized for finishing and precision surface quality.
3. Is coolant necessary?
Yes. For stainless steel turning, high-pressure coolant is highly recommended to control temperature and prevent work hardening.
Industrial Insight: YBM351 is your safety grade. If your tools are chipping during interrupted cuts in 304/316 stainless, this is the solution to stabilize your production.
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.
