Hertel 7000443 Indexable Boring Bar 1.2in Bore Left Hand

Product Description

The HERTEL 7000443 is a left-hand indexable boring bar designed for precision internal boring operations on CNC lathes and turning centers. Built to toolholder style A16SCLPL3, it accepts CP.. 32.52 series inserts secured by screw clamping. The bar features a 1-inch shank diameter and a 12-inch overall length, providing rigidity and reach for demanding boring applications. Through-coolant delivery via a 1/4-27 NPT coolant hole thread keeps the cutting zone clear and helps extend insert life. The steel construction offers durability in production environments where consistent bore geometry is required.

This boring bar is suited for shops running left-hand turning operations that require a minimum bore diameter of 1.2 inches and a maximum bore depth of 3 inches. The through-coolant feature makes it a practical choice for deep-bore work where chip evacuation and heat management are critical. It is typically installed and used by machinists and tooling technicians in job shops, production machining facilities, and manufacturing operations requiring repeatable internal diameter control.

Key Features

• Left-hand holder orientation for compatible left-hand turning setups
• Through-coolant capable with 1/4-27 NPT coolant hole thread for effective chip and heat management
• Screw-clamping insert holding method for secure, repeatable insert positioning
• Accepts CP.. 32.52 series inserts
• Steel construction for rigidity and wear resistance
• Back of bar to cutting edge: 0.64 inches

Compatibility

Designed for use with CP.. 32.52 series inserts in A16SCLPL3 toolholder-style setups. The minimum bore diameter using a diamond insert cartridge is 0.375 inches as specified by the manufacturer.

Installation Notes

Installation and setup should be performed by a qualified machinist or tooling technician familiar with lathe tooling and insert-clamping systems. Ensure the machine spindle is fully stopped and the machine is powered down before mounting or removing the boring bar. Verify shank clamping torque meets your machine tool manufacturer's specifications for a 1-inch shank. Confirm coolant line connections are secure before resuming through-coolant operation.
