CNMG120404-MJ VP05RT
Super Alloy Specialist | VP05RT High-Hardness PVD | MJ Stability Geometry
Engineered for High-Speed Excellence in Tough Materials
VP05RT Grade (High-Wear Miracle PVD): The VP05RT grade is the high-hardness evolution of Mitsubishi’s "Miracle" series. It utilizes a specialized substrate paired with a dense PVD coating to provide maximum wear resistance. It is specifically designed for S-Class (Super Alloys) and hardened materials where tool life is usually cut short by extreme heat and abrasive wear.
MJ Chipbreaker (The Stable Performer): The MJ geometry is a semi-finishing to medium-duty breaker. It features a robust edge design that prevents chipping when encountering the unpredictable micro-structures of Titanium and Nickel-based alloys. It ensures excellent chip control even at the high surface speeds required to prevent work-hardening.
0.4mm (1/64") Precision Radius: The 04 radius is the "accuracy king." By reducing the contact area between the tool and the workpiece, it significantly lowers radial cutting forces. This is vital for preventing chatter and maintaining tight tolerances on thin-walled or high-precision components.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CNMG120404-MJ | 12.7 mm | 4.76 mm | 0.40 mm |
| Imperial | CNMG431-MJ | 1/2" | 3/16" | 0.0157" (1/64") |
Recommended Cutting Parameters
*VP05RT is optimized for high-speed finishing. Use high-pressure coolant to maximize crater wear resistance.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Nickel Alloys (Inconel 718) | 40 - 80 m/min | 0.08 - 0.20 mm/r | 0.30 - 2.00 mm |
| Hardened Steel (40-50 HRC) | 80 - 150 m/min | 0.05 - 0.15 mm/r | 0.20 - 1.50 mm |

VP05RT (The Speed Star): Choose this grade when high surface speed is possible and wear resistance is the priority. It excels in long continuous finishing cuts.
VP10RT (The Versatile Toughness): Switch to VP10RT if you encounter vibrations or minor interrupted cuts, as it offers a higher degree of fracture toughness.
