Material Science & Chip Control
VP15TF Grade: The "Miracle Coated" PVD carbide substrate offers a perfect balance of toughness and wear resistance. It prevents built-up edge (BUE) on stainless steels and remains stable under high thermal loads when cutting titanium or nickel-based alloys.
MA Chipbreaker: Designed for Medium-range cutting, the MA geometry features a specialized rake angle that ensures smooth chip evacuation at varying depths of cut, reducing vibration in long-reach CNC turning applications.

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.
