VP15TF Miracle Grade
The VP15TF grade is a fusion of a high-toughness micro-grain substrate and a specialized PVD Miracle coating. This allows the indexable turning insert to resist built-up edge (BUE) and chipping, making it the primary choice for stainless steel machining and low-to-medium carbon steels.
MA Medium-Cut Breaker
The MA chipbreaker features a geometry optimized for medium cutting applications. It provides excellent chip evacuation across varied feed rates, preventing the workpiece surface from being damaged by continuous chips, especially in gummy materials like SUS304.
Recommended Cutting Parameters
| Material Group | Speed ($v_c$) | Feed per Rev ($f$) | DOC ($a_p$) |
|---|---|---|---|
| Stainless Steel (300 Series) | 80 - 180 m/min | 0.15 - 0.45 mm/rev | 1.0 - 4.0 mm |
| Carbon/Alloy Steel | 100 - 220 m/min | 0.15 - 0.40 mm/rev | 1.0 - 4.0 mm |

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.
