Hertel 7000495 Indexable Boring Bar Right Hand E08SDUPR2

Product Description

The HERTEL 7000495 is a right-hand indexable boring bar built for precision internal boring operations in machining and metalworking environments. Constructed from solid carbide, it delivers the rigidity and wear resistance required for demanding bore finishing work. The bar features a minimum bore diameter of 0.73 inches (18.54 mm), a maximum bore depth of 3 inches (76.20 mm), and an overall length of 8 inches (203.20 mm). Through-coolant capability is built in via a 0.1870-inch coolant hole, supporting chip evacuation and extended tool life during deep bore passes. Insert retention is handled by a screw-clamp method for repeatable edge positioning.

This boring bar is suited for CNC turning centers and manual lathes in production and job-shop environments where consistent bore geometry is required. The E08SDUPR2 toolholder style accepts DP.. 21.51 series inserts, which are commonly used in finishing and semi-finishing passes on steel, cast iron, and similar materials. When equipped with a diamond insert cartridge, the minimum bore diameter extends down to 0.25 inches, expanding the range of bore diameters this bar can service. It is typically installed by machinists and toolroom professionals operating turning or boring equipment.

Installation Notes

Installation is performed by qualified machinists following shop safety procedures. The machine spindle must be fully stopped and locked out before mounting or removing the boring bar. Ensure the shank is fully seated and clamped to the specified turret or toolholder torque per the machine manufacturer's guidelines. Verify coolant line connection to the through-coolant port before initiating a cutting cycle.
