Hertel H08614745 Indexable Boring Bar Right Hand Steel

Product Description

The HERTEL H08614745 is a steel indexable boring bar designed for internal turning and boring operations on lathes and machining centers. Built to the HBBG toolholder style, it accepts WPGT inserts secured by a screw-clamping method, providing repeatable insert positioning and rigid cutting performance. The bar has a minimum bore diameter of 0.26 inches and a maximum bore depth of 0.748 inches, making it well suited for small-bore finish and semi-finish applications. The 3/16-inch shank diameter and 4-inch overall length give it reach and clearance in tight bore profiles. Coolant-through capability supports chip evacuation and extended insert life in production environments.

This boring bar is used in precision machining environments where small internal diameters require consistent, repeatable tooling. It is a right-hand cut configuration, appropriate for standard lathe rotation on conventional and CNC turning centers. Machinists working on components with bore diameters at or above 0.26 inches and bore depths up to 0.748 inches will find this bar a direct-fit toolholder for WPGT insert geometries. It is not a multi-use tool and is intended as a dedicated boring bar for the specified bore range.

Key Features

• Minimum bore diameter of 0.26 inches with maximum bore depth of 0.748 inches
• HBBG toolholder style with screw-clamp insert holding for secure WPGT insert retention
• Right-hand cut orientation for standard lathe rotation
• Coolant-through design supports chip evacuation and insert longevity
• Steel construction provides rigidity in small-bore applications
• 3/16-inch shank diameter and 4-inch overall length for compact reach

Compatibility

Designed for use with WPGT series indexable inserts. Compatible with lathe and CNC turning center tooling systems that accept a 3/16-inch round shank boring bar in the HBBG style.

Installation Notes

Installation should be performed by a qualified machinist familiar with indexable tooling 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. Set shank overhang to the minimum required for the bore depth to maximize rigidity and minimize chatter. Verify insert seating and screw torque according to the insert manufacturer's guidelines before initiating a cut.
