ZCC.CT KNUX160405R11 YBC151 turning insert
Precision High-Speed Finishing for Steel Applications
Product Overview
The ZCC.CT KNUX160405R11 YBC151 is a specialized 55° parallelogram turning insert engineered for the ISO P10-P20 steel range. The YBC151 grade features a thick Al2O3 and TiN CVD coating that provides an exceptional thermal barrier, allowing for high-speed continuous cutting. Combined with the R11 chipbreaker, this insert excels in profiling and finishing operations where precise chip control and surface integrity are non-negotiable.
Key Features
- ✔ YBC151 CVD Coating: Thick layer technology optimized for crater wear resistance during high-velocity machining.
- ✔ R11 Geometry: A precision-ground right-hand chipbreaker designed for aggressive chip evacuation at low depths of cut.
- ✔ Substrate Integrity: High-hardness carbide base ensures minimal plastic deformation at the cutting edge.

— Luigi B., Italy 🇮🇹⭐⭐⭐⭐
"Very consistent performance in batch production. Right-hand orientation is precise."
— Kenji S., Japan 🇯🇵Frequently Asked Questions
Q: Can YBC151 handle interrupted cuts?
A: YBC151 is a high-hardness grade optimized for continuous finishing. For heavy interrupted cuts, we recommend using YBC252 or YBC351.
Q: What is the benefit of the R11 chipbreaker?
A: The R11 is specifically designed for profiling. It ensures that chips do not wrap around the workpiece or tool holder, even at small cutting depths.
Q: Does this work with stainless steel?
A: While it can cut some stainless, YBC151 is optimized for P-group steel. For stainless steel, the YBM series is a better match.
Industrial Tech Tip: When using YBC151 for finishing, ensure your cutting speed (Vc) is high enough to enter the thermal softening zone for the chip, which dramatically improves surface finish and reduces tool pressure.
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.
