JDMW140520ZDSR-FT VP15TF
Mitsubishi Materials | AJX14 Series Heavy-Duty High-Feed Milling
The Mitsubishi JDMW140520ZDSR-FT VP15TF is a premium high-feed milling insert engineered for the AJX14 series—the largest in the AJX family. Designed for massive metal removal rates (MRR), this insert is the go-to solution for heavy-duty roughing in large-scale components. By utilizing the FT (Flat Top) chipbreaker, this insert prioritizes maximum edge strength, while the VP15TF Miracle PVD coating ensures exceptional performance across Carbon Steel, Alloy Steel, and Stainless Steel.

VP15TF Miracle Coating
The VP15TF grade is Mitsubishi's flagship for versatility. Combining a micro-grain carbide substrate with the Miracle PVD coating, it provides high hardness and thermal stability. It is particularly effective at preventing built-up edge (BUE) when indexable milling stainless steel or gummy low-carbon steels.
FT (Flat Top) Geometry
The FT chipbreaker is the "Hardened Specialist." It features a flat-top, high-strength edge that lacks the aggressive rake of the JM or JL breakers. This makes it uniquely suited for roughing through hard skin, forged surfaces, and interrupted cuts where impact toughness and fracture resistance are critical.

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.
