JOMT080320ZZSR-JM MP9120
Mitsubishi Materials | AJX08 Series Exotic Alloy & Titanium Specialist
The Mitsubishi JOMT080320ZZSR-JM MP9120 is a high-feed milling powerhouse specifically developed for Heat Resistant Super Alloys (HRSA) and Titanium Alloys. Designed for the AJX08 cutter platform, this insert utilizes the ultra-tough MP9120 PVD coating to combat the extreme heat and work-hardening characteristics of exotic materials. The JM chipbreaker ensures a sharp yet reinforced edge, making it the premier choice for aerospace and medical component manufacturing.

| Insert Size | 08 (AJX08 Compatible) |
| Corner Radius (RE) | 2.0 mm (.0787") |
| Grade / Coating | MP9120 (Advanced Al-Ti-Cr-N PVD) |
MP9120 Exotic Grade
The MP9120 grade features a specialized Al-Ti-Cr-N PVD coating with a ultra-fine grain carbide substrate. This combination provides maximum welding resistance and prevents the "plucking" effect often seen when milling Titanium or Inconel. It is engineered to maintain edge hardness at temperatures exceeding 1000°C.
JM High-Feed Geometry
The JM (General Machining) chipbreaker is optimized for chip thinning. By distributing cutting forces over a larger edge area, it reduces the pressure on the tool tip. This is critical for high feed milling titanium, where controlling heat and preventing tool deflection are essential for part accuracy.
Recommended Cutting Parameters
| Workpiece Material | Cutting Speed ($v_c$) | Feed Per Tooth ($f_z$) |
|---|---|---|
| Titanium Alloy (Ti-6Al-4V) | 40 - 80 m/min | 0.4 - 1.0 mm/t |
| Inconel / HRSA | 20 - 50 m/min | 0.3 - 0.8 mm/t |
AJX08 TOOLING SYSTEM
Optimized for AJX 08 Type end mills and modular heads. Ensure high-pressure coolant is used for best results in HRSA.

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.
