The Ultimate Finishing Solution
NX2525 Grade (Precision Cermet): The NX2525 is a titanium-based cermet grade. Cermets are harder than standard carbide and offer superior chemical stability. Because the material does not react with steel at high temperatures, it prevents the workpiece from "sticking" to the edge. This results in incredibly long edge life for finishing passes and a "mirror" surface quality that carbide cannot match.
MV Chipbreaker (High-Versatility Medium): The MV geometry is designed for light to medium cutting. Even though it is a finishing tool, the MV breaker is engineered to handle varied depths of cut while maintaining excellent chip evacuation. It prevents long, bird-nesting chips from scratching your finished surface.
0.4mm (1/64") Radius: The 04 radius is the industry standard for precision finishing. It offers the lowest possible cutting force, which is critical for preventing deflection on small diameters or thin-walled parts.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CPMH080204-MV | 7.94 mm | 2.38 mm | 0.40 mm |
| Imperial | CPMH2.521-MV | 5/16" | 3/32" | 0.0157" (1/64") |
Precision Finishing Parameters
*Cermet thrives at high speeds. For the best mirror finish, run at the upper end of the speed range with light feeds.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Carbon/Alloy Steel | 180 - 350 m/min | 0.05 - 0.20 mm/r | 0.20 - 1.50 mm |
| Ductile Cast Iron | 150 - 300 m/min | 0.08 - 0.25 mm/r | 0.30 - 1.20 mm |

Shop Finishing HoldersPro-Tip: NX2525 vs. Carbide Grades
NX2525 (The Finisher): Use this when the drawing requires a high surface finish (Ra 0.8 or better) and dimensional stability.
Carbide (The Remover): Switch to carbide for roughing or when the depth of cut exceeds 2.0mm, as cermet is more brittle and susceptible to fracture under heavy shock.

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.
