APKT11T312-PM YBG302 ZCC.CT Milling Insert
1.2mm Reinforced Corner | The Ultimate Universal PVD Solution
Product Overview
"Looking for one insert to handle interrupted cuts across steel, stainless, and alloys?"
The APKT11T312-PM YBG302 is ZCC.CT's answer to high-versatility milling. Built on the standard 11mm platform, this insert features a significantly larger 1.2mm radius to protect the cutting edge from thermal and mechanical shocks. The YBG302 Grade is a specialized PVD grade that combines a sub-micron substrate with high-thermal stability coating. It is engineered to perform where other inserts chip, making it the perfect choice for interrupted milling and mixed-material production batches.

General Purpose
Core Advantages
- Universal YBG302 Grade: Superior impact resistance across ISO P, M, K, and S groups.
- 1.2mm Radius Security: Specifically designed to prevent corner breakdown during heavy or interrupted cuts.
- PVD Nano-Coating: Excellent thermal stability reduces thermal cracking in dry or semi-dry milling.
- Sharp but Tough: The PM geometry ensures low cutting resistance while maintaining edge integrity.
Common Applications
- Milling of weldments and parts with irregular surfaces.
- Machining of alloy steels, 304/316 stainless, and cast iron.
- Shoulder milling and face milling in multi-material workshops.
- Suitable for high-load operations where tip security is the top priority.

Global Verified Feedback
"The YBG302 is the only grade that survived our interrupted face milling project on welded steel. Highly recommend for rough shops."
J. Dawson - UK"The 1.2 radius provides so much more security than the 0.8. Excellent tool life on cast iron too."
M. Weber - Germany"Ottimo inserto universale. Lo usiamo sia su acciaio che inox senza problemi."
P. Conti - ItalyFrequently Asked Questions
Yes. 11T3 and 1103 both refer to the 3.97mm thickness. These are compatible with all 11-size holders.
Choose the 1.2mm radius when you need maximum edge strength for roughing or when the component drawing specifies a 1.2mm internal fillet. It is far superior at absorbing impacts.
Universal Machining Pro-Tip:
When utilizing the YBG302 grade for interrupted cutting, using compressed air instead of coolant can often prevent thermal shock cracks, significantly extending the life of the PVD coating in steel machining.
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.
