APKT11T308-PM YBC302 ZCC.CT Milling Insert
Balanced High-Toughness CVD Solution for ISO P Steel Milling
Product Overview
"Need a reliable milling insert that handles both general purpose steel and challenging interrupted cuts?"
The APKT11T308-PM YBC302 is the go-to choice for versatility in ISO P (Steel) machining. Featuring the PM (General Purpose) geometry, it provides smooth chip evacuation and a stable cutting edge suitable for medium-duty milling. The YBC302 Grade is a high-performance CVD coating that offers a perfect blend of wear resistance and extreme toughness. This combination makes it exceptionally reliable when dealing with rough surfaces, inconsistent materials, or less-than-rigid setups.

Verified Customer Feedback
"YBC302 is incredibly stable. We use it for roughing mold plates and it never lets us down, even on heavy cuts."
M. Roberts - USA"Ottimo inserto per acciaio. Resistente e con una buona finitura superficiale."
Fabio L. - Italy"The PM chipbreaker handles chip control well across a range of feeds. Very reliable tool life."
S. Miller - UKTechnical FAQ
Yes. While PR is even more reinforced, PM is the best middle ground. It handles moderate interruptions while requiring less spindle power than a full roughing geometry.
Yes, indexable tooling like APKT 11 works well on manual machines, but ensure you maintain enough feed to allow the chipbreaker to function correctly.
CNC Performance Tip:
When roughing with YBC302, dry milling (using compressed air instead of coolant) is often better for CVD coatings. It prevents thermal shock, which can lead to microscopic cracks in the coating and premature edge failure. If the material is gummy, use high-pressure air to clear chips from the cutting zone.
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.
