DCMT11T308 NX2525
High-Speed Cermet | Robust 0.8mm Radius | Mirror Finish Grade
High-Efficiency Cermet Finishing
NX2525 Grade (Titanium-Based Cermet): Mitsubishi's NX2525 is a micro-grain cermet grade designed for finishing. Unlike carbide, Cermet has a very low chemical affinity for steel, which prevents "Built-up Edge" (BUE). This results in a glossy, mirror-like finish and exceptional dimensional stability. It is the premier choice for high-speed continuous cutting where surface aesthetics are critical.
DCMT Geometry (Positive 55° Diamond): The 55-degree diamond shape provides excellent clearance for profiling and facing. The positive rake angle significantly reduces cutting resistance and heat generation, protecting the workpiece from thermal distortion during the final pass.
0.8mm Radius (Increased Productivity): The 0.8mm (08) radius offers superior edge toughness compared to smaller radii. It allows for higher feed rates while maintaining a high-quality surface finish, making it ideal for larger components or semi-finishing applications where speed is essential.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DCMT11T308 | 9.525 mm | 3.97 mm | 0.80 mm |
| Imperial | DCMT32.52 | 3/8" | 5/32" | 0.0315" (1/32") |
Recommended Cutting Parameters
*Cermet requires high spindle speeds to prevent chipping. The 0.8mm radius allows for more aggressive feeds than smaller radii.
| 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) | 150 - 350 m/min | 0.08 - 0.25 mm/r | 0.30 - 1.50 mm |

NX2525 (Cermet): Specifically optimized for high-speed continuous finishing. It provides a superior "Mirror" finish compared to any coated carbide. However, it is more brittle than carbide and should not be used for heavy interrupted cuts.
VP15TF (PVD Carbide): Use this when toughness is required, such as in interrupted cuts, machining through scale, or when working with stainless steels and superalloys.

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.
Our automatic quantity discount is 6% off for 2–9 items and 12% off for 10 or more items, based on the total product quantity in the cart. Other offers may not combine with this discount; check the applicable offer conditions.
