VP15TF Miracle Coating
The VP15TF Miracle Grade is a multi-layered PVD coating optimized for versatility. It excels in machining stainless steel and alloy steels by providing high resistance to welding (BUE) and oxidation. This grade is famous for its long tool life and stable performance in precision machining across various material groups.
MM Chipbreaker Logic
The MM Chipbreaker (Medium-Cut) is the "all-rounder" geometry. It features a reinforced cutting edge to handle fluctuating cutting resistance. Unlike finishing breakers, the MM is designed to break chips effectively at moderate depths of cut and feed rates, preventing chip entanglement during internal or external CNC turning.

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.
