ZCC.CT CPGT050204 YBC151 Turning Inserts
Product Overview
"Which carbide insert provides the best surface finish and dimensional stability for high-speed precision turning of carbon and alloy steels?"
The CPGT050204 YBC151 is a high-precision 80° rhombic positive insert designed for finishing operations. Utilizing the YBC151 grade—a combination of a specialized CVD coating (thick Al₂O₃ + TiN) and a fine-grained carbide substrate—this tool excels in high-speed steel machining (P10–P20 range). Its geometry is optimized for minimal cutting forces, making it the go-to choice for small-diameter parts where surface integrity and precision are paramount.
Key Performance Features
- ✔ Grade YBC151: Advanced CVD coating ensures extreme wear resistance at high temperatures.
- ✔ Precision Finishing: Specifically designed for stable, high-speed finishing of P-class materials (Steels).
- ✔ Low Cutting Resistance: The positive rake angle reduces tool pressure, preventing workpiece deflection.
- ✔ Edge Sharpness: Maintains a keen cutting edge for superior surface Ra values.

— Marco L., Italy⭐⭐⭐⭐⭐
"精度が非常に高い"
Japan automation line choice. Excellent durability.
— Takashi Y., JapanFrequently Asked Questions
A: While possible for very light finishing, the YBM series (like YBM151/251) is specifically engineered for Stainless Steel applications.
A: The 'G' tolerance ensures higher repeatability in insert mounting, critical for automatic tool offset systems.
A: Yes, the CVD coating in YBC151 provides high thermal stability, though coolant is recommended for the best surface finish.
Material Comparison Tip: When machining Pre-hardened Steels (>HRC40), consider the YBC151 for finishing. For roughing of the same material, the YBC252 grade offers better edge toughness to prevent micro-chipping.
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.
