Seco 02526787 Indexable Drill Insert SCGX07 T250D Carbide

Product Description

The SECO 02526787 is a solid carbide indexable drill insert designed for use with Perfomax series indexable drills. Classified under insert style SCGX with a square 90-degree geometry and a 7-degree relief angle, this insert is manufactured to grade T250D and features a PVD coating process for extended tool life across a broad range of workpiece materials. The inscribed circle measures 0.3126 inches (7.94 mm), the corner radius is 0.0315 inches (0.80 mm), and the insert thickness is 0.1252 inches. It is sized as an 07 insert and is sold individually, with a minimum order quantity of 10 units.

This insert is suited for production drilling operations in metalworking environments where consistent hole quality and insert interchangeability are required. The universal primary workpiece material classification — covering material codes H, M, N, P, and S — makes it applicable across carbon steels, stainless steels, non-ferrous metals, high-temperature alloys, and hardened materials. It is intended for use by machinists, tool and die tradespeople, and CNC operators running Perfomax indexable drill bodies.

Installation Notes

Installation of indexable drill inserts should be performed by qualified machinists or CNC operators with the machine fully powered down and the spindle locked. Use the appropriate torx or hex key specified by the drill body manufacturer to seat the insert — do not overtighten, as this can crack the insert or damage the pocket. Inspect the insert pocket for chips or debris before seating a new insert, and verify the insert is fully indexed and locked before resuming operation.
