Seco 03080535 Indexable Insert Drill 3xd 33.32mm

Product Description

The SECO 03080535 is a 3xD indexable insert drill designed for general-purpose drilling operations in metal fabrication, machining, and manufacturing environments. It accepts two indexable inserts — compatible styles SPGX11T3 and SCGX09T308 — and delivers a maximum drill depth of 100.08mm (3.94 inches) with a cutting diameter of 33.32mm (1.352 inches). The steel body features a 1-1/2 inch Weldon flat and flange shank for secure toolholder engagement, and the drill includes axial concentric coolant-through entry to manage heat and chip evacuation at the cutting zone. This tool is installed and operated by machinists and CNC operators on vertical or horizontal machining centers.

This indexable drill is suited for general-purpose through-hole and blind-hole drilling in production machining applications. The 3xD depth-to-diameter ratio makes it appropriate for moderate-depth bores where rigidity and insert life are priorities. The right-hand cutting direction and coolant-through capability support consistent performance in steel and similar workpiece materials. The SD523 series designation identifies the compatible insert pocket geometry and toolholder interface used with this body.

Key Features

Compatibility

Compatible with SD523 drill style inserts SPGX11T3 and SCGX09T308. Insert size codes 11T3 and 09T308 apply. This body is matched to SD523 series tooling and is not interchangeable with other series insert geometries.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. The machine spindle must be fully stopped and the machine placed in a safe, locked-out state before mounting or removing the drill body. Confirm shank-to-toolholder fit and torque the retention fasteners per the machining center manufacturer specifications. Verify insert seating and lock screw engagement before initiating a cut, and confirm coolant-through passages are clear and the coolant supply is active before drilling.
