Seco 02511873 Indexable Boring Bar 0.315 in Bore 5/8 in Shank

Product Description

The SECO 02511873 is an indexable boring bar designed for precision internal boring and turning operations in metal cutting applications. Part of the Mini Shaft series, this tool features a 5/8 inch shank diameter and a minimum bore diameter of 0.315 inches, making it suited for tight-bore work where clearance is limited. The overall length is 3.52 inches and the center-to-cutting-edge measurement is 0.189 inches. Insert retention uses a screw-clamp method for positive holding during interrupted and continuous cuts. The bar is constructed from steel and includes coolant-through capability to support extended tool life and chip evacuation in demanding machining environments. Installation and use are handled by machinists and CNC tooling technicians.

This boring bar is a multi-use tool rated for both boring and turning applications. The 0-degree lead angle and neutral cut geometry make it applicable across a range of materials and setups. With a head length of 0.73 inches and compatibility with LCEX08 series inserts at insert size code 0804, it fits standard tooling configurations used in CNC lathes and manual boring operations. It is sold individually with a minimum order quantity of one unit.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and locked out before changing inserts or mounting the bar. Use the appropriate torque wrench for the insert clamping screw per the insert manufacturer specification sheet. Verify shank clamping rigidity in the turret or holder to minimize vibration and deflection during the cut.
