Seco 02794477 SCGX12 T250D Carbide Indexable Drill Insert

Product Description

The SECO 02794477 is an indexable drill insert in the SCGX12 style, manufactured from solid carbide with a PVD-applied T250D grade coating. Designed for use in Perfomax series indexable drills, this insert features a 90-degree square shape with a 7-degree relief angle and a 0.80 mm (0.0315 inch) corner radius. The inscribed circle measures 12.70 mm (0.5000 inches) and thickness runs 0.1874 inches. Installation and changeover are performed by machining professionals and tooling technicians during scheduled insert indexing or replacement cycles on CNC and manual drilling operations.

This insert is suited for a wide range of workpiece materials, classified under universal primary workpiece material codes H, M, N, P, and S. That coverage spans steel, stainless steel, non-ferrous metals, cast iron, and superalloys, making it a versatile choice for job shops, production machining environments, and maintenance operations requiring consistent hole-quality performance in Perfomax-compatible drill bodies.

Installation Notes

Insert changeover should be performed by a qualified machining technician with the drill body removed from the spindle and the machine placed in a locked-out, de-energized state per facility lockout/tagout procedures. Use the appropriate torx or hex key as specified by the drill body manufacturer when securing the insert clamp screw. Inspect the insert pocket and clamping surfaces for chips or debris before seating the new insert. Do not exceed the clamping torque recommended in the drill body documentation.
