Seco 03079573 Indexable Insert Drill 1-1/4 in 5xd

Product Description

The SECO 03079573 is a straight-shank indexable insert drill from the PerfoMAX series, designed for high-productivity drilling in metal cutting applications. It accepts two indexable inserts and delivers a maximum drill diameter of 1-1/4 inches (32.31 mm) with a maximum drill depth of 6-1/4 inches, achieving a 5xD depth-to-diameter ratio. The steel tool body features through-coolant capability to manage heat and chip evacuation at the cutting zone. Compatible insert styles include SCGX and SPGX, with insert size codes 09T308 and 11T3. This drill is intended for right-hand cutting and is installed by machinists and toolroom technicians in CNC machining centers and drill presses.

The 03079573 is suited for general-purpose drilling operations in production and job-shop environments. Its 1-1/2 inch straight cylindrical shank fits standard toolholders and collet chucks common in both horizontal and vertical machining centers. The modular connection size is R7, and the neck diameter measures 1.969 inches. Typical applications include through-hole and blind-hole drilling in steel, cast iron, and other machinable metals where consistent bore diameter and depth control are required.

Compatibility

Compatible with SCGX and SPGX indexable inserts in size codes 09T308 and 11T3, including SPGX11T3 style inserts. Designed for use with the SECO PerfoMAX drill series with an R7 modular connection. Fits toolholders accepting a 1-1/2 inch straight cylindrical shank.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the machine is in a locked-out state before inserting or removing the tool from the toolholder. Verify insert seating and screw torque according to the insert manufacturer specifications before beginning a cut. Confirm through-coolant supply lines are clear and delivering adequate flow before initiating drilling operations.
