APKT11T308-PM YBG202 ZCC.CT Milling Insert
0.8mm Standard Radius | High-Precision Nano-PVD Performance
Product Overview
"Looking for a versatile milling insert that delivers both edge security and a superior surface finish?"
The APKT11T308-PM YBG202 is a cornerstone of precision milling. Designed for the versatile 11mm platform, this insert features a standard 0.8mm radius, the industry-preferred specification for general 90° shoulder milling. The YBG202 Grade utilizes ZCC.CT’s advanced Nano-TiAlN PVD coating, known for its smooth surface and high oxidation resistance. This makes it an exceptional choice for ISO P, M, and K materials, offering stable performance even when facing work-hardening stainless steels or alloyed steels.

Core Advantages
- Precision YBG202 Grade: Balanced PVD grade for high-speed finishing and semi-finishing.
- Standard 0.8mm Radius: The ideal balance between edge strength and precision finish for most industrial parts.
- Nano-Structured Coating: Reduces friction and prevents built-up edge (BUE) on stainless steel.
- Smooth Chip Removal: PM geometry provides excellent control across a wide feed range.
Common Applications
- 90° shoulder milling in 304/316 and other stainless steels.
- Semi-finishing of alloyed steels and cast iron components.
- High-precision contouring and profiling in CNC centers.
- Multi-purpose milling in job shops requiring high tool versatility.

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 YBG202 if your priority is surface finish and stable machining of a variety of materials. If you are doing heavy interrupted cuts or roughing, YBG302 provides slightly more toughness.
CNC Performance Pro-Tip:
When milling stainless steel with YBG202, using high-pressure coolant directed at the cutting edge is vital. This prevents the nano-coating from overheating and ensures the chips are evacuated quickly to avoid re-cutting, which is the primary cause of sudden insert 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.
