Seco 74077371 Indexable Drill Insert SPGX06C1 T400D

Product Description

The SECO 74077371 is a square SPGX-style indexable drill insert designed for use with Perfomax series indexable drills. Made from solid carbide with a PVD-applied coating and T400D manufacturer grade, this insert is built for consistent performance across a wide range of workpiece materials. It features an inscribed circle diameter of 0.2500 inches (6.35 mm), an included angle of 90 degrees, and an 11-degree relief angle. The C1 chipbreaker geometry promotes controlled chip evacuation in demanding drilling applications. Installation and replacement are performed by machinists and tooling technicians working on CNC and manual drilling operations.

This insert is rated for universal material compatibility, covering material codes H, K, M, N, P, and S. That range encompasses steels, stainless steels, cast irons, non-ferrous metals, and superalloys, making the 74077371 a versatile tooling choice for job shops and production environments running varied workpiece materials. It is sized at 0602 and fits Perfomax series drill bodies configured for SPGX06 inserts.

Installation Notes

Insert seating and clamping should be performed with the drill body secured and machine power off. Use the correct torx or clamping screw driver as specified by the drill body manufacturer to achieve proper seating without overtightening. Inspect the insert pocket for chips, debris, or wear before installing a new insert, as a contaminated pocket can cause premature edge failure or runout. Minimum order quantity for this insert is 10 pieces.
