Hertel 7000048 Indexable Boring Bar 0.98 in Right Hand

Product Description

The HERTEL 7000048 is a right-hand A-SVUB indexable boring bar designed for precision internal turning operations on CNC lathes and manual turning centers. Built from steel with a 0.75-inch shank diameter and a 10-inch overall length, this bar accepts VB.. 332 inserts secured by a screw clamp method. The neutral rake geometry and -3-degree lead angle support controlled chip formation and stable cutting across a range of ferrous and non-ferrous workpiece materials. A through-coolant design with a 1/8-27 NPT coolant inlet keeps the cutting zone cool and aids chip evacuation during deep-bore operations.

This boring bar is suited for production and job-shop turning applications requiring a minimum bore diameter of 0.98 inches. The through-coolant capability makes it particularly effective in deep-bore finishing and semi-finishing passes where chip packing is a concern. Machinists and CNC operators in general machining, aerospace, and fluid-power component shops will find the 0.5620-inch center-to-cutting-edge dimension useful for precise tool-offset setup. Sold individually.

Key Features

• Minimum bore diameter of 0.98 inches supports a wide range of internal turning applications
• Through-coolant design with 1/8-27 NPT inlet improves chip evacuation and tool life in deep bores
• Screw-clamp insert holding method provides rigid, repeatable insert indexing
• Neutral rake angle (0 degrees) with -3-degree lead angle for stable cutting geometry
• 1/4-inch insert inscribed circle with 1/8-inch insert thickness using VB.. 332 compatible inserts
• Steel construction with 0.75-inch shank diameter for solid machine interface

Compatibility

Accepts VB.. 332 A-SVUB style inserts with a 1/4-inch inscribed circle and 1/8-inch thickness. Designed for use in tool holders and turrets accommodating a 0.75-inch round shank boring bar.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician with the spindle fully stopped and the machine in a locked-out state before mounting or indexing inserts. Ensure the shank is clamped to the full recommended engagement depth in the tool block or turret to minimize overhang-related vibration. Connect the coolant supply line to the 1/8-27 NPT inlet and verify flow before initiating the cut. Follow the insert manufacturer torque guidance for the screw clamp to avoid insert seat damage.
