APKT11T308-PM YB9320 ZCC.CT Milling Insert
0.8mm Standard Radius | Advanced Nano-PVD for Stainless Steel
Product Overview
"Need a reliable insert that conquers the stickiness and heat of stainless steel?"
The APKT11T308-PM YB9320 represents the premium tier of ZCC.CT's milling lineup. While the 0.8mm radius provides the versatility needed for 90° shoulder milling across diverse components, the YB9320 Grade is the star performer. It is engineered with a high-toughness substrate and a nano-structured PVD coating that offers exceptional resistance to "built-up edge" and thermal cracking. Whether you are machining 304, 316, or tricky alloy steels, this insert ensures stable tool life and high-efficiency metal removal.

Core Advantages
- Premium YB9320 Grade: Exceptional heat resistance and toughness for unstable stainless steel machining.
- Anti-Adhesion Coating: Specially treated PVD surface prevents metal chips from welding to the insert edge.
- Stable Edge Geometry: PM chipbreaker provides excellent chip control while maintaining a sharp cutting action.
- High Reliability: Optimized for semi-finishing to roughing, even in mildly interrupted cuts.
Application Scenarios
- Milling of austenitic stainless steels (304, 316, 316L).
- Processing of heat-resistant alloys and duplex stainless steel.
- Efficient shoulder milling in low-carbon steel components.
- General milling where tool life consistency is a priority.
Technical Data & Parameters
| Metric Model | Inch Equivalent | Cutting Speed (Vc) | Feed per Tooth (fz) |
|---|---|---|---|
| APKT11T308-PM | APKT 0.433" x 0.156" R0.031" | 120 - 280 m/min | 0.10 - 0.25 mm/z |
*Optimal speed varies by material hardness. Use high-pressure coolant for best results in stainless steel.

Technical FAQ
Yes. 11T3 (3.97mm) is the ISO standard designation. 1103 is often used interchangeably to indicate the same thickness. Both fit the same 11-size holders.
YB9320 is a higher-tier grade specifically optimized for the unique thermal properties of stainless steel. It offers better resistance to the chemical and heat-related wear that usually causes early failure in universal grades.
Stainless Steel Pro-Tip:
When machining stainless steel with YB9320, ensure you maintain a consistent minimum feed rate. Stainless steel tends to work-harden; if the feed is too light, the insert will "rub" against the work-hardened layer, causing rapid edge wear.
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.
