Seco 03134326 Indexable Drill Insert SPGX19MC DS4050

Product Description

The SECO 03134326 is a square indexable drill insert in the SPGX19MC style, engineered for use with Perfomax series indexable drills. It is manufactured from solid carbide with a PVD-applied DS4050 grade coating, providing wear resistance across a broad range of workpiece materials. The insert features a 3/4 inch (0.7500 inch) inscribed circle, a 90-degree included angle, and an 11-degree relief angle. The MC chipbreaker geometry promotes controlled chip evacuation during drilling operations. This insert is installed by machinists and CNC operators performing hole-making in production environments.

The 03134326 is suited for drilling applications in universal material groups, covering ISO material codes M, N, P, and S. These codes correspond to stainless steels, non-ferrous materials, carbon and alloy steels, and heat-resistant superalloys respectively. The Perfomax platform is used in both manual and CNC machining centers for production drilling. Cutting action is bidirectional, supporting both left-hand and right-hand cutting directions. Typical applications include through-hole and blind-hole drilling in job shop and high-volume production settings.

Compatibility

Designed for use with SECO Perfomax series indexable drill bodies that accept SPGX-style inserts with a 19 insert size code (1904). Verify seat geometry and screw torque specifications in the Perfomax toolholder documentation before installation.

Installation Notes

Insert replacement should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before accessing the insert pocket. Use the correct Torx or hex key as specified by the toolholder manufacturer to secure the clamping screw — do not substitute fasteners. Inspect the insert seat and clamping screw for wear or damage each time inserts are indexed or replaced.
