JDMW120420ZDSR-FT VP15TF
Mitsubishi Materials | AJX12 Series Heavy-Duty High-Feed Milling
The Mitsubishi JDMW120420ZDSR-FT VP15TF is an industrial-strength high-feed milling insert engineered for the AJX12 series cutter bodies. This 12-size insert is the backbone of high-efficiency roughing, designed for maximum metal removal rates (MRR). Utilizing the FT (Flat Top) chipbreaker for enhanced edge strength and the legendary VP15TF Miracle PVD coating, this insert excels in Carbon Steel, Alloy Steel, and Stainless Steel, specifically where edge chipping is a concern.

VP15TF Miracle Coating
The VP15TF grade is Mitsubishi's most versatile PVD coated carbide. It features a micro-grain carbide substrate that offers a perfect balance of toughness and hardness. The Miracle Coating effectively resists built-up edge (BUE) and heat-related wear, making it the top choice for indexable milling stainless steel and tough alloy steels.
FT (Flat Top) Chipbreaker
The FT (Flat Top) geometry is designed for maximum fracture resistance. Unlike more aggressive rakes, the FT chipbreaker provides a strengthened cutting edge that withstands the heavy impact of interrupted cuts and high table feeds. This makes it ideal for rough machining through scale or forging surfaces.
