Hertel 7000419 Indexable Boring Bar Left Hand 6in

Product Description

The HERTEL 7000419 is a left-hand indexable boring bar designed for precision internal boring operations on CNC lathes and turning centers. Built to toolholder style A06MSCLCL2, it accepts CC..21.51 series inserts secured by screw clamping. The bar features a 3/8-inch shank diameter and an overall length of 6 inches, with a minimum bore diameter of 0.48 inches and a maximum bore depth of 1.125 inches. Through-coolant capability is standard, supporting extended tool life and chip evacuation in tight-bore applications. The steel construction provides rigidity for consistent finish and dimensional control.

This boring bar is suited for small-bore turning work in job shop and production environments. It is most applicable in applications where left-hand tool orientation is required, such as specific turret positions or back-turning setups. The through-coolant design makes it effective when machining deeper bores or gummy materials that generate significant heat. A minimum bore diameter of 0.25 inches is achievable when using a diamond insert cartridge configuration, expanding its utility across a range of bore sizes.

Key Features

• Left-hand holder orientation for specific turret and back-turning setups
• Through coolant with a 0.13-inch coolant hole diameter for effective chip and heat management
• Accepts CC..21.51 series inserts via screw clamping for secure, repeatable indexing
• Minimum bore diameter of 0.48 inches standard; 0.25 inches with diamond insert cartridge
• Steel construction for rigidity and vibration resistance in small-bore applications
• Back of bar to cutting edge measures 0.25 inches for close-clearance work

Compatibility

Designed for use with CC..21.51 series inserts in A06MSCLCL2 toolholder style. Compatible with standard 3/8-inch shank boring bar setups on CNC lathes and turning centers that support left-hand tooling.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Secure the shank in a properly sized boring bar holder and verify turret orientation matches left-hand cutting direction before operation. Ensure the coolant supply line is connected and the through-coolant port is clear before engaging the spindle. Follow machine tool manufacturer guidelines for toolholder torque and insert clamping procedures.
