Description

The SECO 74077370 is a solid carbide indexable drill insert in the SPGX05C1 T400D configuration, designed for use in indexable drill bodies within the Perfomax series. The insert features a square shape with a 90-degree included angle and an 11-degree relief angle, providing positive cutting geometry suited for a wide range of workpiece materials. The PVD-applied TiAlN and TiN dual coating improves wear resistance and heat tolerance during drilling operations. With a 0.2189-inch (5.56 mm) inscribed circle and a thickness of 0.094 inches, this insert is sized for the 05 insert size code. Licensed machinists and CNC operators working in production or job-shop environments are the typical installers.

This insert is rated for universal application across multiple material grades, including cast iron (K), non-ferrous metals (N), steel (P), stainless and heat-resistant alloys (S), hardened materials (H), and general-purpose medium-alloy materials (M). It is intended for use in compatible Perfomax series indexable drill bodies where the SPGX insert style and 05 size code are specified. It is sold individually with a minimum order quantity of 10 units.

Installation Notes

Insert seating and torque should be performed by a qualified machinist or CNC tooling technician per the drill body manufacturer specifications. Ensure the drill body pocket is clean and free of chips or debris before seating the insert. Power down and lock out the machine spindle before changing inserts. Do not exceed the recommended cutting parameters published by SECO for the T400D grade and target workpiece material.
