Hertel 7000461 Indexable Boring Bar 0.93 in Right Hand

Product Description

The HERTEL 7000461 is a right-hand indexable boring bar designed for precision internal boring operations on CNC lathes and machining centers. Built to A12STLPR3 toolholder style specifications, it accepts TP.. 32.52 series inserts secured by a screw-clamp holding method. The steel shank measures 0.75 inches in diameter with an overall length of 10 inches, allowing reach into bores with a maximum depth of 2.25 inches. A built-in through-coolant channel threaded at 1/8-27 NPT delivers cutting fluid directly to the insert tip, supporting tool life and chip evacuation in demanding bore finishing and semi-finishing applications.

This boring bar is suited for job shops, production turning cells, and tool rooms running ferrous and non-ferrous materials. The 0.93 inch minimum bore diameter makes it appropriate for medium-bore internal turning work. When fitted with a triangle insert cartridge, the minimum bore diameter extends down to 0.375 inches, expanding its range of usable setups. It is intended for installation by machinists and tooling technicians in shop environments where indexable turning toolholders are standard.

Key Features

• Right-hand cutting orientation for standard lathe turret and boring bar holder setups
• Through-coolant capability via 1/8-27 NPT coolant hole for directed flood or high-pressure coolant delivery
• Accepts TP.. 32.52 inserts with screw-clamp holding for repeatable edge indexing
• 0.75 inch shank diameter and 10 inch OAL provide rigidity across the 2.25 inch maximum bore depth
• Steel construction for durability in production boring environments
• Triangle insert cartridge compatibility reduces minimum bore diameter to 0.375 inches

Compatibility

Designed for use with TP.. 32.52 series indexable inserts as specified for the A12STLPR3 toolholder style. Compatible with boring bar holders accepting a 0.75 inch round shank.

Installation Notes

Installation is performed by qualified machinists following shop tooling procedures. Ensure the machine spindle is fully stopped and the turret or tool block is locked before mounting or removing the boring bar. Torque the shank set screws to the machine tool manufacturer's specification for the holder being used. Connect the through-coolant line to the 1/8-27 NPT port using appropriate fittings rated for the system operating pressure before initiating a cutting cycle.
