Hertel H08614950 Indexable Boring Bar Left Hand Steel

Product Description

The HERTEL H08614950 is a steel indexable boring bar designed for internal turning and boring operations on CNC lathes and manual turning centers. Built to toolholder style HBBS, it accepts WPMT inserts secured by a screw clamping method, providing repeatable cutting geometry and fast insert changes. The bar features a 0.75-inch shank diameter and an overall length of 8 inches, with a minimum bore diameter of 0.8 inches and a maximum bore depth of 3 inches. Coolant-through capability allows direct coolant delivery to the cutting zone, helping to manage heat and chip evacuation in deep bore applications. This tool is installed by machinists and CNC operators in production and job-shop environments.

This boring bar is suited for left-hand cutting operations in both ferrous and non-ferrous bore finishing and semi-finishing applications. The screw-lock insert holding method keeps the WPMT insert firmly seated under interrupted cuts and continuous passes alike. With a 3-inch maximum bore depth, it handles moderate-depth bores typical in shaft work, housing bores, and sleeve fits. It is appropriate for use in standard ANSI-dimension tool blocks and turrets that accept a 0.75-inch round shank.

Key Features

• Left-hand cut orientation for specific lathe setup requirements
• Coolant-through design delivers fluid directly to the insert tip for heat and chip control
• Screw clamping method for secure, repeatable WPMT insert seating
• 0.8-inch minimum bore diameter enables work on tight-diameter bores
• Steel construction provides rigidity for accurate bore geometry
• 3-inch maximum bore depth suits a wide range of standard bore lengths

Compatibility

Designed as an OEM-style indexable boring bar using WPMT series inserts; verify insert grade and geometry selection based on workpiece material and cutting parameters.

Installation Notes

Installation is performed by qualified machinists or CNC setup personnel. Ensure the machine spindle is fully stopped and the turret or tool block is de-energized before installing or removing the boring bar. Secure the shank to the specified clamping torque for your toolholder system per the machine tool manufacturer guidelines. Confirm coolant-through supply lines are connected and free of obstruction before initiating a cut.
