APMT 1604PDER-WK OS5105B Carbide Milling Insert

Description

The APMT 1604PDER-WK OS5105B carbide milling insert is designed for productive CNC milling operations where stable cutting, controlled chip formation and dependable tool life are required. The APMT 1604 format is commonly used in 90° shoulder mills, face mills and end mills for general-purpose milling of steel, stainless steel and cast iron. The PDER right-hand geometry with WK chipbreaker supports smooth entry into the cut and helps reduce cutting load, making it suitable for roughing to semi-finishing operations on a wide range of components. OS5105B is a carbide grade intended for practical workshop use where consistent performance and good value are important. This insert is suitable for machining flat surfaces, shoulders, pockets and edges when used in compatible APMT/APKT 1604 milling cutter bodies. Recommended cutting data below are safe starting ranges and should be adjusted according to machine rigidity, coolant use, tool overhang, workpiece material and required surface finish.
