Seco 02450443 Indexable Boring Bar 0.433 in Bore

Product Description

The SECO 02450443 is an indexable boring bar designed for internal boring and turning operations on CNC lathes and manual turning centers. Part of the Mini Shaft series, it features a 5/8-inch shank diameter and a minimum bore diameter of 0.433 inches, making it well suited for small-diameter internal work where clearance is tight. The bar uses a screw-clamping insert holding method for secure seating under cutting load. Overall length is 3.88 inches. Compatible inserts are LCEX11.. style in size code 1105 with a rectangular insert shape. Coolant-through capability is built in, supporting chip evacuation and tool life in continuous cuts.

This boring bar is intended for professional machinists and toolroom technicians working on small-bore applications in both production and job-shop environments. The neutral cut geometry and zero lead angle make it adaptable to both boring and turning applications on the same setup, reducing tool changes. Its multi-use designation means it can transition between boring and turning passes within a single operation. The Mini Shaft series is suited for sliding headstock machines, small gang-tool lathes, and compact turret setups where shank real estate is limited.

Installation Notes

Installation and setup should be performed by a qualified machinist or toolroom technician. Secure the shank in the toolholder or turret to the full recommended clamping depth before engaging a cut. Confirm insert seating and screw torque per the insert manufacturer's clamping guidelines before initiating spindle rotation. Always verify clearance between the bar body and bore wall before beginning the operation.
