Mitsubishi VCMT160404 NX2525
Premium Cermet Turning Insert for High-Speed Finishing
The Mitsubishi VCMT160404 NX2525 is a professional-grade 35° rhombic positive displacement cermet turning insert. Engineered specifically for steel finishing, the NX2525 grade provides excellent oxidation resistance and low affinity for workpiece materials, preventing built-up edge (BUE) and ensuring a mirror-like high surface finish on CNC lathe components.
This VCMT 331 ANSI equivalent insert is the industry standard for precision dimensional control in stable cutting conditions.

Material & Chipbreaker Details
NX2525 Grade (Cermet): A Ti(C, N) based uncoated cermet. It is optimized for high-speed finishing where thermal stability and chemical inertness are critical. It significantly reduces tool wear when cutting carbon steel and alloy steel.
MV Chipbreaker: Designed for light cutting to medium-light loads. The geometry ensures superior chip control at lower depths of cut, preventing long, stringy chips from scratching your finished surface.
Cutting Parameters (Recommended)
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Carbon Steel | 150 - 350 m/min | 0.05 - 0.20 mm/rev | 0.2 - 1.5 mm |
| Alloy Steel | 100 - 250 m/min | 0.05 - 0.15 mm/rev | 0.2 - 1.0 mm |
Perfect Compatibility
This insert is designed to fit standard SVJCR and SVVCN tool holders.

NX2525 is your first choice for the ultimate glossy finish on steel. However, if your application involves high-speed continuous cutting of stainless steel, consider MP7035. For interrupted cutting or roughing where toughness is required over surface finish, a coated carbide grade like UE6020 is recommended.
