Product Description
The SECO 03134324 is a solid carbide indexable drill insert designed for use in Perfomax series indexable drills. Featuring the SPGX insert style with an MC chipbreaker, this square-shaped insert measures 0.5000 inches inscribed circle and carries a DS4050 manufacturer grade. The TiAlN and NbN PVD coating provides wear resistance and heat tolerance across a broad range of workpiece materials. The 90-degree included angle and 11-degree relief angle are engineered for reliable chip formation and stable cutting performance. Installation requires a compatible Perfomax drill body and is performed by machinists and tooling technicians in production or job-shop environments.
This insert is suited for universal application across multiple material groups, including code designations M, N, P, and S, covering carbon steels, stainless steels, non-ferrous metals, and heat-resistant alloys. The Perfomax series is a common platform in CNC turning centers and machining centers for hole-making operations. The insert is sold individually and is a direct replacement insert for Perfomax drill bodies accepting the 12T3 insert size.

Installation Notes
Insert installation and indexing should be performed with the machine powered down and spindle locked. Use the correct Torx or hex key specified by the drill body manufacturer to seat the insert securely in the pocket. Inspect the insert pocket and clamping screw for wear or damage before installing a new insert. Follow the tooling manufacturer guidelines for seating torque class and insert orientation to prevent premature edge failure.
