Mitsubishi VNMG160408-SH NX2525
Premium Cermet Grade for High-Precision Steel Finishing
The Mitsubishi VNMG160408-SH NX2525 is a professional-grade 35° rhombic negative cermet turning insert. Unlike traditional carbide, the NX2525 cermet grade utilizes a ceramic-metal composite to deliver a mirror-like high surface finish on steel workpieces. This VNMG 332-SH ANSI equivalent is optimized for high-speed finishing where dimensional accuracy and aesthetic gloss are the top priorities.

- ANSI (Imperial): VNMG 332-SH
NX2525 Cermet & SH Geometry
NX2525 Cermet Grade: Cermet (Ceramic + Metal) provides a high chemical affinity for steel, which prevents "built-up edge" (BUE). The NX2525 micro-grain cermet allows for much higher cutting speeds than standard carbide, ensuring the tool maintains a sharp edge for high-precision steel finishing.
SH Chipbreaker: The SH geometry is specifically designed for finishing at low depths of cut. It features a sharp rake angle that reduces cutting resistance and minimizes work hardening on the workpiece, resulting in a superior surface gloss.
Recommended Cutting Parameters
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Carbon Steel (Finishing) | 150 - 350 m/min | 0.08 - 0.25 mm/rev | 0.3 - 1.5 mm |
| Alloy Steel (Finishing) | 120 - 280 m/min | 0.05 - 0.20 mm/rev | 0.3 - 1.2 mm |
System Integration
For maximum surface quality, pair this VNMG 332 insert with our high-rigidity tool holders.

NX2525 Cermet is superior for high-speed finishing and mirror finishes. However, if your application involves heavy interrupted cuts or roughing, carbide grades like UE6110 or MC6025 are recommended for better impact resistance.

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.
