Core Performance Benefits:
- Superior Anti-BUE Coating: The specialized PVD coating prevents "Built-Up Edge," the primary cause of poor surface finish and tool failure in stainless steel.
- Golden Ratio Radius: The 0.4mm (R0.4) radius is ideal for both semi-finishing and finishing, offering enough strength to resist chipping while delivering excellent光洁度.
- Thermal Shock Resistance: Designed to excel in both wet and dry machining, resisting the cracks that often occur due to rapid temperature changes.
- Versatile 09 Size: Fits a wide range of standard tool holders and boring bars, making it an essential stock item for any CNC workshop.

Choosing between PC9030 and PC5300:
Best for general finishing, small holes, and high-precision parts. Provides the smoothest surface finish.
Best for interrupted cuts, roughing, or unstable setups. More resistant to impact and chipping.
Machinist's Tip: If your work material is very gummy and sticks to the tool, PC9030 is your best first choice.
Packaging: 10 pieces per box.
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.
