ZCC.CT APKT160408-PF YBG302 Inserts
Professional PVD Nano-TiAlN Coated Carbide for Versatile Precision Milling
Product Overview
"Which milling insert grade offers the best heat resistance and edge toughness for finishing stainless steel and alloy steel components?"
The ZCC.CT APKT160408-PF YBG302 is a world-class indexable milling solution designed for multi-material excellence. Utilizing the advanced YBG302 PVD Nano-TiAlN coating, this insert provides a superior thermal barrier and oxidation resistance. The PF chipbreaker (Precision Finishing) features a highly positive rake angle that slices through gummy materials like 304 stainless steel with minimal cutting force, effectively eliminating vibration and ensuring a mirror-like surface finish.
Key Features
- ✔ Nano-TiAlN PVD Coating: Optimized for medium-speed milling of high-temperature alloys and stainless steels.
- ✔ PF Finishing Geometry: Sharp, precision-ground cutting edge specifically designed for high-quality surface requirements.
- ✔ Universal Substrate: A balanced ultra-fine carbide grain that provides the edge security needed for interrupted cuts.

ZCC.CT Grade Material Comparison
YBG302 vs. YBC301: While YBC301 utilizes CVD coating for high-speed steel roughing, YBG302 is a PVD Nano-grade that offers superior edge sharpness. The PVD process allows for a thinner, tighter coating layer on the sharp PF chipbreaker, which is critical for stainless steel applications where a dull edge would cause work-hardening and poor tool life. For precision finishing, YBG302 is the superior choice.
Customer Success Stories
"Genuine ZCC.CT quality. The YBG302 grade is a beast on 316 stainless steel. Finishing is mirror-like."
— David S., USA"Ausgezeichnete Standzeit. Die PF-Geometrie bricht die Späne perfekt bei niedrigen Schnitttiefen."
— Hans M., Germany"Great value. Replaced our expensive EU brands with these for finishing ops."
— Marco L., Italy"Reliable ZCC.CT performance. Dimensional accuracy is consistent over long batches."
— Sato Y., JapanFrequently Asked Questions
Is YBG302 suitable for dry milling?
Yes. The Nano-TiAlN coating has excellent thermal stability, allowing it to perform well in dry milling or with minimal quantity lubrication (MQL).
What is the recommended depth of cut for the PF chipbreaker?
The PF chipbreaker is optimized for finishing. We recommend a depth of cut (Ap) between 0.3mm and 2.0mm for optimal chip control.
Material Pro Tip: Finishing Stainless
When finishing stainless steel with the APKT160408-PF YBG302, avoid allowing the insert to "dwell." Constant feed is required to prevent the cutting edge from rubbing, which leads to immediate work-hardening and premature coating failure.
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.
