CCMT060202 AP25N
High-Speed Finishing | TiCN Cermet Grade | Mirror Finish Specialist
Material & Geometry Analysis
AP25N Grade (TiCN Cermet): This is a Titanium Carbonitride-based cermet designed specifically for Steel finishing. AP25N features exceptional resistance to oxidation and plastic deformation. Because it has a low chemical affinity for steel, it virtually eliminates Built-Up Edge (BUE), allowing for incredible surface gloss and dimensional stability over long production runs.
Positive 80° Rhombic Geometry: The CCMT design is a positive rake insert, which reduces cutting forces and heat generation. This makes it ideal for boring bars and slender workpieces where vibration control is essential. The 0.2mm radius is perfect for fine finishing and intricate profiles.
Model & Dimensional Comparison
| Unit System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CCMT060202 | 6.35 mm | 2.38 mm | 0.20 mm |
| Imperial | CCMT21.50.5 | 0.250" (1/4") | 0.0937" (3/32") | 0.0079" |
Recommended Cutting Parameters
*AP25N performs best in dry machining or with minimal lubrication for high-gloss results. Use higher speeds to prevent chipping.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Carbon Steel (S45C) | 180 - 350 m/min | 0.03 - 0.12 mm/r | 0.1 - 1.0 mm |
| Alloy Steel (SCM440) | 150 - 300 m/min | 0.03 - 0.10 mm/r | 0.1 - 0.8 mm |

Shop SCLCR ToolingSelection Tip: AP25N vs VP15TF
AP25N (Cermet): Choose for Continuous Finishing. It provides a better surface finish and higher speed capability in steel than carbide.
VP15TF (PVD Carbide): Switch to VP15TF for Interrupted Cuts or Stainless Steel. Cermet is brittle and may chip in heavy interruptions where carbide survives.

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.
