Seco 03080728 Indexable Insert Drill 26.97mm 2xd

Product Description

The SECO 03080728 is a straight-shank indexable insert drill from the PerfoMAX series, designed for general-purpose drilling in metal fabrication and machining operations. It accepts two indexable inserts and produces a bore diameter of 26.97mm (1.0620 inches) to a maximum drill depth of 53.85mm, representing a 2xD depth-to-diameter ratio. The tool body is constructed from steel and features through-coolant capability, making it suitable for demanding production environments. Installation and operation require a CNC machining center or similar equipment configured for right-hand cutting.

This drill is intended for use in production machining applications where consistent hole quality and repeatable insert positioning are required. The straight cylindrical shank measures 1-1/4 inches in diameter with a shank length of 2.375 inches, fitting standard toolholders used in vertical and horizontal machining centers. The modular connection size is R7. Compatible insert styles are SCGX and SPGX, with compatible insert size codes 070308 and 0903. The series designation is PerfoMAX, and the compatible drill style is SD522.
