ZCC.CT APKT160408-PF YBC301 Inserts
Advanced CVD Coated Carbide for High-Speed Steel Finishing Operations
Product Overview
"Which milling insert is most effective for achieving superior surface finishes in steel while maintaining high cutting speeds?"
The ZCC.CT APKT160408-PF YBC301 is a high-performance milling solution specifically engineered for steel (P-class) machining. Featuring the YBC301 CVD Al2O3 + TiCN coating, this insert is built to withstand high temperatures generated during high-speed cutting. The PF chipbreaker is precision-honed for finishing to semi-finishing, providing exceptional chip control and reducing cutting resistance. Its 0.8mm radius is the industry standard for 90° square shoulder milling where precision and edge integrity are paramount.
Key Features
- ✔ Thick CVD Coating: Al2O3 + TiCN coating provides a massive heat barrier for stable high-speed machining.
- ✔ PF Finishing Chipbreaker: Sharp cutting edge and positive rake angle reduce power consumption and BUE (Built-up Edge).
- ✔ Substrate Toughness: A gradient carbide substrate ensures the edge remains intact during moderate interrupted cuts.

ZCC.CT Grade Material Comparison
YBC301 vs. YBG202: While YBG202 is a PVD grade versatile for multiple materials, YBC301 is a specialized CVD steel grade. The thick Al2O3 layer in YBC301 provides significantly higher crater wear resistance at high temperatures. If you are milling carbon or alloy steel at high speeds, YBC301 will offer a 40% longer tool life and better thermal stability than PVD-coated alternatives.

— Kenji S., JapanFrequently Asked Questions
Is YBC301 suitable for stainless steel?
YBC301 is primarily optimized for steel (P). For stainless steel (M), we recommend ZCC.CT YBM grades or YBG202 for better results.
What depth of cut (Ap) is recommended for PF chipbreakers?
The PF (Finishing) chipbreaker is best used with an Ap between 0.5mm and 2.5mm for optimal chip breaking.
Material Pro Tip: High-Velocity Cutting
When using APKT160408-PF YBC301, do not be afraid to push the cutting speed (Vc). CVD coatings like the one on YBC301 require heat to activate the Al2O3 thermal barrier effectively. Cutting too slowly can actually reduce tool life by preventing the coating from reaching its optimal performance state.
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.
