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
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
