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.
