JDMT140520ZDSR-JM FH7020
Mitsubishi Materials | AJX Series Heavy-Duty Cast Iron Specialist
The Mitsubishi JDMT140520ZDSR-JM FH7020 is a heavy-duty high-feed milling insert specifically engineered for high-speed machining of Cast Iron (Gray & Ductile). Designed for the AJX14 series cutters, this insert leverages the FH7020 PVD coated grade to provide superior abrasion resistance in brittle and abrasive materials. The JM chipbreaker (General Machining) offers a strengthened cutting edge, ensuring stable metal removal even at aggressive feed rates common in high-efficiency CNC milling.

FH7020 Grade Efficiency
The FH7020 grade is a specialized PVD-coated carbide optimized for flank wear resistance. In cast iron milling, the abrasive nature of the material often leads to rapid tool wear; FH7020 uses a hard, heat-resistant layer to maintain edge sharpness, reducing machine downtime and improving surface finish consistency.
JM Chipbreaker Advantage
The JM (General Machining) geometry features a reinforced cutting edge. This design prevents chipping during the heavy impact of high-feed milling. It effectively thins the chip for smoother evacuation, reducing the thermal load transferred to the tool and workpiece.

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.
