DCMT11T308-MV NX2525
Mirror-Finish Specialist | MV Versatile Chipbreaker | 0.8mm Heavy Finishing
Superior Aesthetics via Cermet Technology
NX2525 Cermet Grade: The NX2525 is a Titanium Carbonitride (TiCN) based Cermet. Unlike standard tungsten carbide, Cermet does not "weld" to steel workpieces at high temperatures. This prevents Built-Up Edge (BUE), resulting in a mirror-like surface finish and excellent dimensional consistency over long production runs.
MV Chipbreaker (Medium Finishing): The MV (Medium-V) geometry is a versatile chipbreaker designed for stability. It covers a wider range of cutting depths and feed rates than ultra-fine finishers, ensuring smooth chip evacuation and preventing "bird-nesting" during automated production.
0.8mm Nose Radius (Strength & Surface): The "08" (1/32") radius offers significant edge strength. It is ideal for semi-finishing passes where you need to remove more material while still achieving a high-gloss final surface. The larger radius also allows for higher feed rates without sacrificing $Ra$ values.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DCMT11T308-MV | 9.525 mm | 3.97 mm | 0.80 mm |
| Imperial | DCMT32.52-MV | 3/8" | 5/32" | 0.0315" (1/32") |
Recommended Cutting Parameters
*Cermet requires high speeds to achieve optimal gloss. Avoid heavy interrupted cuts.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Carbon Steel (1045) | 200 - 450 m/min | 0.10 - 0.30 mm/r | 0.30 - 2.00 mm |
| Alloy Steel (4140) | 180 - 380 m/min | 0.08 - 0.25 mm/r | 0.25 - 1.50 mm |

NX2525 (Cermet): The choice for aesthetic finishing on steel. It is much harder and more heat resistant than carbide, producing a brighter finish at higher speeds.
VP15TF (PVD Carbide): Use this if your cut is interrupted (e.g., holes or keyways). Cermet is brittle and may chip under shock. Also, use carbide for Stainless Steel applications.

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.
