JDMW120420ZDSR-FT MP6130
Mitsubishi Materials | AJX Series High-Efficiency Steel Milling
The Mitsubishi JDMW120420ZDSR-FT MP6130 is a specialized high-feed milling insert engineered for high-speed metal removal in Carbon and Alloy Steels. Designed for the AJX12 cutter series, this insert features the MP6130 PVD coating, a grade specifically optimized to combat heat and wear in steel milling. The FT (Flat Top) geometry provides a reinforced, high-strength cutting edge, making it the primary solution for heavy roughing and machining through tough surface skins or scale.
Technical Specifications

|---|---|
| ANSI Designation (Inch) | JDMW 434ZDSR-FT |
| Insert Size | 12 (For AJX 12 Type Cutters) |
| Corner Radius (RE) | 2.0 mm (.0787") |
| Grade / Coating | MP6130 (Al-Ti-Cr-N PVD Coating) |
MP6130 Steel Grade
The MP6130 grade is a specialized PVD coated carbide for ISO-P Steel applications. It employs an accumulated Al-Ti-Cr-N coating that offers superior thermal crack resistance. This makes it highly effective for dry milling where heat flux is high, significantly extending tool life compared to general-purpose grades.
FT (Flat Top) Chipbreaker
The FT geometry is a flat-top chipbreaker engineered for maximum edge strength. By removing aggressive rakes, the FT design minimizes the risk of edge chipping when milling through interrupted cuts or forged surfaces. It is the most reliable choice for heavy-duty roughing in the AJX system.
