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.

- ANSI (Imperial): VCMT 331
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.

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.
