ZCC.CT CCMT09T304-HM YBC151: High-Speed Precision Steel Finishing
Product Overview
The ZCC.CT CCMT09T304-HM YBC151 is the professional's choice for precision steel turning (P-group). The YBC151 grade features a high-wear-resistance substrate combined with a thick Al2O3 and TiCN CVD coating, engineered for high cutting speeds where thermal resistance is paramount. With a precision 0.4mm (0.016") nose radius and the HM chipbreaker, this insert provides superior surface integrity and stable chip breaking even at lower feed rates.
Key Features
- YBC151 Wear-Resistant Grade: Specifically optimized for high-speed finishing of carbon and alloy steels (P05-P15 range).
- HM Chipbreaker: Designed for stable medium-to-finishing operations, providing excellent chip control across varying depths of cut.
- CVD Coating Technology: Advanced multi-layer coating reduces friction and crater wear during prolonged machining.
- Precision 0.4mm Radius: Minimizes cutting force and vibration, making it perfect for slender shafts and thin-walled parts.

Frequently Asked Questions
Q: Can I use YBC151 for interrupted cutting?
A: YBC151 is optimized for high-speed continuous cutting. For heavy interrupted cuts, we recommend the tougher YBC251 grade.
Q: What is the benefit of the 04 (0.4mm) radius over the 08 (0.8mm)?
A: The 0.4mm radius generates lower cutting forces and heat, making it superior for fine surface finishes and machining thin-walled parts.
Q: Is this insert compatible with stainless steel?
A: While it can cut ferritic stainless steel, it is primarily designed for steel. For austenitic stainless steel (304/316), the YBM series is highly recommended.
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.
