Material: VP15TF PVD Coating
VP15TF is Mitsubishi’s premium universal grade. It combines a tough micro-grain carbide substrate with a specialized PVD coating. This coating offers exceptional oxidation resistance and adhesion prevention, making it the top choice for milling stainless steel where built-up edge (BUE) often causes tool failure.
Geometry: Flat-Top (N-Type)
The N-type geometry indicates a flat-top face without a molded chipbreaker. This design maximizes the volume of carbide behind the cutting edge, providing superior impact resistance for interrupted cuts and high-feed roughing in manual or CNC machines.
Recommended Cutting Parameters
| Material | Cutting Speed ($v_c$) | Feed per Tooth ($f_z$) |
|---|---|---|
| Carbon Steel | 100 - 220 m/min | 0.10 - 0.25 mm/t |
| Stainless Steel | 80 - 160 m/min | 0.08 - 0.20 mm/t |
| Cast Iron | 100 - 180 m/min | 0.15 - 0.35 mm/t |

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.
