ZCC.CT CCMT120404-HF YBC151: Ultimate Finishing for Steel Machining
Product Overview
"Which insert grade and chipbreaker combination delivers the highest surface gloss and most reliable chip breaking during high-speed precision finishing of alloy steels?"
The ZCC.CT CCMT120404-HF YBC151 is a high-performance turning insert precision-engineered for the P-group (Steel). The YBC151 grade utilizes a thick CVD coating (TiCN + Al2O3) to provide exceptional thermal stability and wear resistance in continuous high-speed cutting. The HF (High Finishing) chipbreaker features a specialized sharp edge and rake angle design, specifically optimized to handle small depths of cut while maintaining perfect chip evacuation, ensuring a mirror-like surface on carbon and alloy steels.
Key Features
- Advanced YBC151 CVD Coating: Thick Al2O3 layer ensures maximum resistance to heat and crater wear during high-speed machining.
- HF (High-Finishing) Geometry: Specifically designed for precision finishing with outstanding chip control at very low feed rates.
- Exceptional Edge Strength: The high-strength carbide substrate prevents chipping and ensures dimensional consistency.
- Sharp R0.4 Radius: Reduces cutting resistance and prevents vibration, making it ideal for thin-walled and small-diameter parts.

"We run our machines at full speed in Germany with YBC151. Very predictable tool life and extremely stable edge."
— Dieter M., Germany
"Excellent Chip Control"
"The HF geometry handles small depths of cut perfectly in our automated lathe. No birds-nesting."
— Luca F., Italy
"Consistent Japanese Quality"
"Even after 500 parts, the dimensional accuracy is still within 0.005mm. Amazing reliability from ZCC.CT."
— Sato K., Japan
Frequently Asked Questions
Q: When should I choose HF over HM chipbreakers?
A: Choose HF for finishing passes with very small depths of cut (Ap < 0.5mm). Choose HM for general purpose semi-finishing and larger depths of cut.
Q: Is this insert suitable for dry machining?
A: Yes, the CVD coating on YBC151 is highly heat-resistant and performs exceptionally well in dry or high-speed wet machining environments.
Q: Can I use this for stainless steel?
A: While it can cut stainless, we recommend the YBM series (e.g. YBM251) which is specifically designed for stainless steel to prevent work hardening and edge sticking.
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.
