Seco 02493655 Milling Insert SPMX0903AP-75 F40M Carbide

Product Description

The SECO 02493655 is a solid carbide milling insert carrying the ANSI/ISO designation SPMX0903AP-75 in manufacturer grade F40M. It is a square-shaped, single-sided insert with a neutral rake and T-Land cutting edge style, designed for use in indexable milling cutters on CNC and manual milling machines. The insert features a PVD-applied TiAlN and TiN dual-coating on a fine-grain carbide substrate, delivering wear resistance and thermal stability across a broad range of workpiece materials. With four usable cutting edges, a 0.375 inch inscribed circle, and a 0.1252 inch thickness, this insert suits medium to finish milling passes at controlled depths of cut up to 0.375 inches.

This insert is intended for milling operations on steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It is well suited for production machining environments where consistent tool life and predictable edge performance are required across material transitions. The 75 chip breaker geometry supports controlled chip evacuation in face milling and shoulder milling applications. Machinists and CNC operators working in job shops, aerospace, and general manufacturing will find this insert appropriate for light to medium roughing and semi-finishing passes on the listed workpiece materials. Cutter compatibility is confirmed for SECO cutter series R215.39, R215.49-3, and R417.19-3.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the spindle before indexing or replacing inserts. Use the correct Torx or hex key specified by the cutter body manufacturer to seat the clamping screw — do not overtighten. Inspect the cutter pocket seating surface for chips or damage before seating the new insert to ensure proper edge geometry and runout.
