JOMW080320ZZSR-FT VP15TF
Mitsubishi Materials | AJX08 Series Heavy-Duty High-Feed Milling
The Mitsubishi JOMW080320ZZSR-FT VP15TF is an industrial-grade high-feed milling insert engineered for the AJX08 series cutter bodies. This specific "W" type insert features the FT (Flat Top) chipbreaker, which is the most robust geometry in the lineup. It is designed for maximum metal removal rates (MRR) in challenging conditions. By combining the VP15TF Miracle PVD coating with a reinforced edge, this insert excels in roughing carbon steel, alloy steel, and stainless steel where edge stability is the highest priority.

VP15TF Miracle Coating
The VP15TF grade is Mitsubishi's premier solution for versatility. It features a micro-grain carbide substrate that offers a perfect balance of toughness and hardness. The Miracle PVD Coating (Al-Ti-N based) provides excellent built-up edge (BUE) resistance, which is critical when indexable milling stainless steel and gummy alloy steels.
FT (Flat Top) Geometry
The FT (Flat Top) chipbreaker is engineered for extreme edge strength. Unlike the JM or JL breakers, the FT design eliminates the aggressive rake to provide a blunt, reinforced edge. This makes it the superior choice for rough machining through scale, forged surfaces, and heavy interrupted cuts where high fracture resistance is mandatory.
