Seco 03080507 Indexable Insert Drill 7/8 in 3xd

Product Description

The SECO 03080507 is a 7/8 inch (0.8750 inch decimal) indexable insert drill from the PerfoMAX series, designed for general-purpose drilling in metalworking and machining applications. Built with a straight cylindrical shank measuring 1 inch in diameter, the drill body accepts two indexable inserts — compatible styles include SCGX and SPGX — allowing insert replacement without removing the full tool from the spindle. Maximum drill depth is 66.8 mm at a 3xD depth-to-diameter ratio. Coolant-through capability supports chip evacuation and heat management during production drilling. The tool body is constructed from steel and weighs approximately 2.0 pounds.

This drill is suited for production and job-shop environments where consistent hole quality and repeatable depth performance are required. The PerfoMAX platform is engineered for general-purpose drilling in steel, cast iron, and similar workpiece materials on CNC machining centers and drill presses with adequate spindle rigidity. The straight cylindrical shank interfaces with standard toolholders accepting a 1 inch shank. The modular connection size is R7, and the neck diameter measures 1.378 inches. Shank length is 2.25 inches and overall body length is approximately 96.8 mm.

Installation Notes

Installation and setup should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool is secured in a properly rated toolholder before tightening. Verify coolant-through supply lines are connected and flow is confirmed before initiating a cut. Follow the machine tool manufacturer and insert manufacturer recommendations for feed rate and speed parameters appropriate to the workpiece material.
