Coolant :Wet AH7025 provides stability, while preventing coating from peeling off evenafter machining twice the number of passes compared to the conventional grade.

The combination of Nano-multi-layered AlTiN Coating with

high Al content and tough substrate provides highly efficient

machining in various grooving operations
