Mitsubishi VCMT110304 NX2525
High-Precision Cermet Grade for Superior Surface Finishing
The Mitsubishi VCMT110304 NX2525 is a premium 35° rhombic positive displacement cermet insert designed specifically for the high-speed finishing of steel and ductile cast iron. Unlike traditional carbide, the NX2525 cermet grade provides exceptional resistance to built-up edge (BUE) and oxidation, ensuring a mirror-like surface finish on your workpieces.
Ideal for CNC lathe precision turning, this insert is your first choice when surface quality and dimensional accuracy are non-negotiable.

Advanced Material Technology
NX2525 Cermet Grade: Cermet (Ceramic-Metal composite) is renowned for its high chemical stability. The NX2525 grade is a versatile, uncoated cermet that provides an excellent balance of wear resistance and toughness. It excels in stable cutting conditions, preventing the material from sticking to the tool (BUE).
Chipbreaker Geometry: Designed for light depths of cut, this chipbreaker ensures smooth chip evacuation at high speeds, reducing heat buildup and protecting the cutting edge.
Cutting Parameters (Recommended)
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Low 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 |

Use NX2525 when you need the highest surface gloss on steel. If you are machining under unstable or interrupted cutting conditions, consider switching to VP15TF (PVD coated carbide) for higher impact resistance. For mass production of stainless steel, US735 is the preferred choice.

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.
