ZCC.CT TCMT220408 YBC151
Premium CVD Coated Carbide Inserts for High-Speed Steel Turning
Product Overview
"Which carbide insert provides the best surface finish and wear resistance for high-speed continuous turning of carbon and alloy steels?"
The ZCC.CT TCMT220408 YBC151 is a high-performance triangular turning insert optimized for ISO P (Steel) materials. Featuring the advanced YBC151 grade—a thick Al2O3 CVD coating combined with a high-hardness substrate—this insert is specifically designed to excel in high-speed, dry or wet continuous cutting environments. It offers unmatched stability and tool life where precision and surface integrity are paramount.
Key Industrial Advantages
Superior Wear Resistance
The thick TiCN and Al2O3 coating layers provide exceptional protection against crater wear and flank wear at high temperatures.
High-Speed Optimization
Engineered for stable, high-velocity continuous machining (Vc up to 450 m/min) in carbon, alloy, and tool steels.
Precision Geometry
The positive 7° relief angle reduces cutting forces, making it ideal for thin-walled parts and internal boring operations.

— Kenji S., Japan 🇯🇵Technical FAQ
Q: Is YBC151 suitable for interrupted cuts?
A: YBC151 is a high-hardness grade optimized for continuous cutting. For heavy interrupted cuts, we recommend switching to the YBC351 grade for better impact toughness.
Q: Can I use this for stainless steel?
A: While it can cut some ferritic stainless steels, YBC151 is specifically optimized for Carbon and Alloy Steels (ISO P). For Austenitic Stainless (304/316), please use the YBM series.
Q: Does this insert require coolant?
A: It performs excellently in both dry and wet conditions. In high-speed steel turning, dry cutting with compressed air is often preferred with CVD coatings to prevent thermal shocking.
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.
