VP15TF Miracle Coating
The VP15TF grade is Mitsubishi's versatile PVD Miracle coating. It offers extreme wear resistance and resistance to oxidation. Because of its excellent adherence to the carbide substrate, it is highly effective at preventing built-up edge (BUE), making it the premier choice for stainless steel turning and heat-resistant alloys.
FM Chipbreaker Design
The FM Chipbreaker (Finishing-Medium) is engineered for high-precision finishing. It features a sharp cutting edge and a specific rake profile that curls chips tightly even at very low depths of cut. This prevents long "bird-nesting" chips from scratching the workpiece, ensuring a high-quality surface finish.

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.
