Hertel H08614935 Indexable Boring Bar Left Hand Steel

Product Description

The HERTEL H08614935 is a left-hand indexable boring bar designed for precision internal turning and boring operations on metal cutting machines. Built from steel, this toolholder uses a screw-type insert holding method compatible with WPMT-style inserts. It features a 5/8-inch shank diameter and an overall length of 7 inches, making it well-suited for shops that need reliable, repeatable bore geometry on CNC lathes and manual turning equipment. Coolant-through capability allows for improved chip evacuation and extended insert life during continuous cutting cycles. This bar is a single-use toolholder style, not a multi-use configuration.

This boring bar is intended for machining environments where left-hand cutting geometry is required, typically in situations involving back-boring or specific lathe setup orientations. The HBBS toolholder style accommodates a minimum bore diameter of 0.675 inches and a maximum bore depth of 2.5 inches. It is appropriate for job shops, production machining facilities, and maintenance operations where close-tolerance internal diameters are required. Professional machinists and CNC operators handling steel and similar materials will find this bar fits standard toolpost and turret setups with a 5/8-inch shank pocket.

Key Features

• Left-hand cutting orientation for back-boring and specialized lathe setups
• Coolant-through design improves chip flushing and insert longevity
• Screw-type insert retention provides secure clamping with WPMT inserts
• 0.675-inch minimum bore diameter with up to 2.5-inch maximum bore depth
• Steel construction for rigidity and durability in metalworking applications
• HBBS toolholder style for consistent, repeatable setup

Compatibility

Designed for use with WPMT-style indexable inserts. Compatible with machine tool setups requiring a 5/8-inch shank diameter boring bar with left-hand cutting geometry.

Installation Notes

Installation and setup should be performed by a qualified machinist familiar with indexable toolholder systems. Ensure the machine spindle is fully stopped and all motion has ceased before changing inserts or adjusting the bar in the turret or toolpost. Verify proper shank clamping torque per the machine tool manufacturer guidelines and confirm insert seating before taking any cuts. Do not exceed the maximum bore depth rating of 2.5 inches to avoid deflection or insert failure.
