VP15TF Miracles Coating
The VP15TF grade features a micro-grain carbide substrate with an AlTiN-based Miracle coating. This grade is optimized for stable machining by reducing chemical wear and thermal cracking. It is highly effective for lathe turning in stainless steel where built-up edge (BUE) often ruins surface quality.
FS "Super-Finish" Breaker
The FS chipbreaker provides a high-positive rake angle that significantly lowers cutting resistance. This allows for superior chip evacuation even at light depths of cut, ensuring that your CNC boring process results in a flawless, scratch-free 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.
