Seco 02829673 Indexable Boring Bar 0.5 in Shank 6 in Oal

Product Description

The SECO 02829673 is a steel-bodied indexable boring bar designed for internal turning operations on CNC lathes and manual turning centers. With a minimum bore diameter of 0.571 inches and a 0.5 inch shank diameter, it fits a wide range of standard toolholders and boring head setups. The bar accepts a diamond-shaped insert held by a screw-clamp mechanism and runs a negative rake angle of 0 degrees with a 95-degree lead angle. Coolant-through capability supports chip evacuation and tool life in deep or tight-bore applications. Machinists and toolroom technicians working in production or maintenance turning will find this bar a direct, indexed solution for precision bore work.

This boring bar is suited for right-hand cutting on internal diameters in ferrous and non-ferrous materials. At 6 inches overall length, it handles moderate-depth bore applications without excessive overhang. The screw-in insert retention keeps setup repeatable across index cycles, reducing downtime during insert changes. Compatible insert size code is 21.5, which should be confirmed against the applicable insert catalog before ordering. This bar is not configured as a multi-use tool and is intended specifically for turning rather than milling or grooving operations.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before mounting or removing the boring bar. Secure the shank in the toolholder to the manufacturer-specified clamping depth and confirm runout before cutting. Always verify insert size and grade compatibility before indexing to a new cutting edge.
