Hertel 7000453 Indexable Boring Bar 0.98in Right Hand

Product Description

The HERTEL 7000453 is a right-hand indexable boring bar designed for precision internal turning and boring operations on CNC lathes and machining centers. Built from steel with a 3/4-inch shank diameter and a 10-inch overall length, this toolholder accepts VB..221 series inserts secured by a screw-clamp holding method. The minimum bore diameter is 0.98 inches and the maximum bore depth reaches 2.25 inches, making it well-suited for moderate-depth internal features. Through-coolant capability is supported via a 1/8-27 NPT coolant hole, enabling effective chip evacuation and heat management during continuous cutting cycles. Licensed machinists and CNC operators specify this bar for consistent, repeatable bore geometry.

This boring bar is intended for use in production and job-shop machining environments where indexable tooling is preferred over solid carbide for cost efficiency and insert replaceability. The A12SSVQBR2 toolholder style is a recognized series configuration for steel-shank boring applications. It is suited to horizontal and vertical turning centers where a 3/4-inch shank mount is available. The through-coolant feature makes it appropriate for materials that generate significant heat or require continuous chip removal, such as steel, stainless, and cast iron.

Key Features

• Minimum bore diameter of 0.98 inches with a maximum bore depth of 2.25 inches
• 3/4-inch shank diameter, 10-inch overall length for reach into moderate-depth bores
• Right-hand cut orientation for standard lathe and turning center setups
• Through-coolant design with 1/8-27 NPT coolant port for improved chip control and tool life
• Screw-clamp insert holding method for secure, repeatable insert indexing
• Accepts VB..221 series inserts for broad cutting geometry availability

Compatibility

Designed to accept VB..221 series inserts. Toolholder style is A12SSVQBR2 in the Series A boring bar lineup. Minimum bore diameter using a diamond insert cartridge is 0.25 inches.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle and turret are fully stopped and the machine is in a safe, locked-out state before mounting or adjusting the toolholder. Verify shank clamping torque per the machine tool manufacturer specifications and confirm insert seating and screw torque per the insert manufacturer guidelines before cutting. Through-coolant connections should be checked for proper sealing at the 1/8-27 NPT port before initiating coolant flow.
