Dorian Tool 73310194764 Milling Insert Apkt 1604

Product Description

The DORIAN TOOL 73310194764 is a solid carbide, PVD-coated milling insert designed for face and shoulder milling operations in metalworking applications. The insert follows the APKT-1604 designation and carries the DMC35UM manufacturer grade, indicating a wear-resistant coating engineered for demanding cutting conditions. It features a parallelogram shape with an 85-degree included angle, positive rake geometry, and an 11-degree relief angle. A 0.0315-inch (0.80 mm) corner radius helps distribute cutting forces and extend edge life. Installation is by screw-clamp holding method. This insert is used by machining professionals in job shops, manufacturing facilities, and toolroom environments.

This insert is optimized for machining stainless steel, corresponding to ISO material group M. Its positive rake and PDSR chip breaker geometry promote efficient chip evacuation and reduced cutting forces when working with tough, work-hardening alloys. The APKT-style insert seats in compatible right-hand toolholders and is suitable for face milling, shoulder milling, and light profiling passes. Maximum depth of cut is 0.0800 inches. It is a single-sided insert, meaning one usable cutting edge per corner orientation.

Installation Notes

Insert installation should be performed by a qualified machinist or toolroom technician. Shut down the machine spindle and engage the lockout before handling or indexing inserts. Use the correct torque screwdriver or insert wrench for the APKT screw-clamp system to avoid stripping the mounting screw. Inspect the insert pocket and seating surfaces for chips or debris before seating the insert.
