Dorian Tool 73310195294 Milling Insert Solid Carbide Sdgx

Product Description

The DORIAN TOOL 73310195294 is a solid carbide, PVD-coated milling insert engineered for precision material removal on non-ferrous metals. Conforming to ANSI code SDGX-19C16-E-DUP25GT, this single-sided, square-shaped insert features a grade designation of DUP25GT and delivers a positive rake geometry with a 15-degree relief angle. It measures 0.75 inches in length and width with a thickness of 0.1875 inches, and carries a corner radius of 0.2500 inches. With four cutting edges and a screw-type holding method, it offers repeatable indexing and consistent performance in milling applications. Machining professionals and toolroom technicians install this insert in compatible SDGX-series milling toolholders.

This insert is designed for milling operations on non-ferrous workpiece materials, including aluminum alloys and similar materials coded N under standard material classification systems. Its positive rake face geometry and chip breaker designation E support efficient chip evacuation and reduced cutting forces, making it well suited to high-speed finishing and semi-finishing passes. It fits into SDGX-series toolholders used on CNC machining centers and manual mills in both production and job-shop environments. The screw-clamp holding method provides secure seating and straightforward indexing during routine insert changes.

Installation Notes

Installation is performed by machining professionals or toolroom technicians on CNC or manual milling equipment. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate Torx or hex key as specified by the toolholder manufacturer to secure the clamping screw - do not overtighten. Inspect the toolholder pocket and seating surfaces for chips or damage before seating a new insert.
