Seco 03080756 Indexable Insert Drill 1-3/4 in 2xd

Product Description

The SECO 03080756 is a straight-shank indexable insert drill from the PerfoMAX series, designed for general-purpose drilling in steel and compatible workpiece materials. It accepts two indexable inserts and provides a maximum drill depth of 3.5 inches at a 2xD depth-to-diameter ratio. The 1.75-inch cutting diameter pairs with a 1.5-inch straight cylindrical shank, making it compatible with standard toolholders used in CNC machining centers and manual lathes. Coolant-through capability supports chip evacuation and tool life in production drilling environments. Licensed machinists and CNC operators are the primary users of this tooling in job shop and manufacturing settings.

The 03080756 is suited for drilling operations in ferrous and general-purpose materials where consistent hole quality and repeatable depth control are required. The right-hand cutting direction and two-insert configuration allow for efficient material removal at the 1.75-inch diameter. Compatible insert styles include SCGX and SPGX, with insert size codes 120408 and 1504 (SPGX1504 series confirmed). The modular connection size is R7, and the collar diameter measures 50 millimeters, which is relevant when selecting toolholder clearance in tight setups.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the toolchanger or turret is in a safe state before mounting or removing the drill body. Verify insert seating and torque fasteners to the insert manufacturer specification before running the tool. Confirm coolant-through passages are clear and coolant pressure is set per machine guidelines before engaging the cut.
