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.

| 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
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
