JDMT120420ZDSR-JM VP15TF
Mitsubishi Materials | AJX Series Large-Scale High-Feed Milling
The Mitsubishi JDMT120420ZDSR-JM VP15TF is a heavy-duty high-feed milling insert engineered for the AJX12 series cutters. This 12-size insert is the powerhouse of the AJX family, designed for maximum metal removal rates (MRR) in large-scale machining. Featuring the advanced VP15TF Miracle PVD coating, it provides exceptional durability in Stainless Steel, Carbon Steel, and Alloy Steels. The JM chipbreaker is specifically designed to manage the high chip loads associated with high-feed milling while maintaining a stable cutting edge.

VP15TF Miracle Coating
The VP15TF grade combines a tough carbide substrate with a specialized PVD coating to resist welding and chipping. This "Miracle Coating" is the standard for stainless steel milling, offering a long tool life by preventing the built-up edge (BUE) often encountered in austenitic materials.
JM Chipbreaker Advantage
The JM (General Machining) chipbreaker is the first choice for high-feed applications. Its optimized rake angle and edge preparation reduce cutting force, which is essential for preventing vibration in long-overhang milling and maintaining dimensional accuracy during heavy roughing.

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.
