CNMM190612-DR YBC151 ZCC.CT Carbide Turning Inserts
Product Overview
"Which carbide insert is best for high-efficiency heavy roughing of steel with excellent wear resistance?"
The CNMM190612-DR YBC151 is a heavy-duty powerhouse designed for the most demanding Steel (P-Class) turning operations. The YBC151 grade features a thick Al₂O₃ CVD coating combined with a high-strength carbide substrate, optimized for high-speed cutting. The DR chipbreaker is specifically engineered for "Double-Sided Roughing," offering a robust cutting edge that handles large depths of cut and high feed rates while maintaining stable chip breaking.
Key Performance Features
- YBC151 Coating: Thick CVD Al₂O₃ coating for extreme wear resistance in high-temperature dry or wet cutting.
- DR Chipbreaker Geometry: Large rake angle and reinforced edge for heavy roughing and improved tool life.
- High Heat Stability: Maintains hardness at high cutting speeds (P10-P20 range).
- Strong Substrate: Minimizes edge chipping during interrupted cuts.

Verified Global Customer Feedback
⭐⭐⭐⭐⭐
"Monster for steel roughing"
In the USA, we use these for heavy shaft roughing. They take an 8mm cut like it's nothing. Better life than our previous brand.
— Robert M., USA⭐⭐⭐⭐⭐
"Sehr stabil"
Great stability at high speeds in our German plant. The YBC151 coating is perfect for dry cutting alloy steel.
— Hans K., Germany⭐⭐⭐⭐
"Affidabile"
Reliable inserts for heavy-duty turning. Good chip breaking with the DR geometry.
— Luca B., Italy⭐⭐⭐⭐⭐
"耐久性が高い"
Very durable for 4140 steel. Price-to-performance ratio is unbeatable.
— Sato Y., JapanFrequently Asked Questions
Q1: Is YBC151 suitable for stainless steel?
A: While it can cut some series, YBC151 is optimized for Steel (P-Class). For stainless, we recommend the YBM series.
Q2: What is the difference between CNMG and CNMM?
A: CNMM features a reinforced geometry specifically for heavy-duty roughing, whereas CNMG is more for general-purpose turning.
Q3: Can these inserts run dry?
A: Yes, the thick CVD Al₂O₃ coating in YBC151 is designed to withstand the high temperatures associated with dry machining of steel.
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.
