APKT11T308-PM YBG302 ZCC.CT Milling Insert
0.8mm Standard Radius | The Ultimate High-Toughness PVD Solution
Product Overview
"Dealing with heavy vibrations or interrupted cuts across various materials?"
The APKT11T308-PM YBG302 is ZCC.CT's most versatile performer for challenging milling environments. The 11mm size fits standard shoulder mills, while the 0.8mm corner radius ensures compatibility with most industrial design requirements. The standout YBG302 Grade combines a sub-micron carbide substrate with a specialized thermal-stable PVD coating. This makes the insert exceptionally resistant to mechanical shock and thermal cracking, allowing it to excel in interrupted milling of steels, stainless steels, and heat-resistant alloys.

General Purpose
Core Advantages
- Tough YBG302 Grade: Specifically engineered for high-impact and interrupted cutting cycles.
- Standard 0.8mm Radius: The ideal balance between edge strength and precision finish.
- Advanced PVD Nano-Coating: Effectively resists thermal shock cracks in dry or high-speed milling.
- Universal Application: One grade to manage Steel (P), Stainless (M), Cast Iron (K), and Superalloys (S).
Application Scenarios
- Milling parts with holes, slots, or irregular entry/exit points.
- High-stability machining of Stainless Steel and Alloy Steel.
- Heavy-duty shoulder milling where tool security is more critical than pure speed.
- Great for job shops with frequent material changes.

Technical FAQ
No. 11T3 (3.97mm) is the ISO standard designation. 1103 is a common alternative label for the same thickness. Both fit the same 11-size tool holders.
Choose YBG302 if you are experiencing edge chipping or if your workpiece has slots/holes that cause "pounding." It is specifically designed to absorb those shocks better than the YBG202 grade.
Interrupted Cutting Pro-Tip:
When utilizing the YBG302 grade for heavy interrupted cuts, using compressed air instead of liquid coolant can often extend the life of the PVD coating by preventing the thermal cycling that causes microscopic cracks on the cutting edge.
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.
