Hertel 7000439 Indexable Boring Bar 0.98 in Right Hand

Product Description

The HERTEL 7000439 is a right-hand indexable boring bar designed for internal turning and boring operations on CNC lathes and machining centers. Built to toolholder style A12SSDUCR3, it accepts DC.. 32.52 inserts secured by a screw-holding method for rigid, repeatable cutting performance. The steel shank measures 3/4 inches in diameter and 10 inches in overall length, providing the reach and rigidity needed for precise bore finishing. A through-coolant port with a 1/8-27 NPT thread delivers coolant directly to the cutting zone, extending insert life and improving chip evacuation during deep boring passes.

This boring bar is suited for precision bore work in ferrous and non-ferrous materials across job shop and production machining environments. Its 0.98-inch minimum bore diameter makes it appropriate for tight bore entry applications, while the 2-1/4-inch maximum bore depth handles a practical range of workpiece geometries. The minimum bore diameter using a diamond insert cartridge drops to 0.375 inches, expanding the tool's range when reconfigured. Licensed machinists and CNC operators working in metalworking, tool-and-die, and general machining will find this bar a standard-duty fit for lathe boring setups.

Installation Notes

Installation should be performed by a qualified machinist familiar with indexable tooling and CNC or manual lathe setup. Ensure the machine spindle is fully stopped and the machine is in a safe, locked-out state before mounting or adjusting the boring bar. Confirm insert seating and screw torque per the insert manufacturer's standard procedure before initiating a cut. Connect the coolant supply line to the 1/8-27 NPT port using appropriate fittings and verify coolant flow before running the tool at depth.
