Hertel 7000080 Indexable Boring Bar 0.6 in Right Hand

Product Description

The HERTEL 7000080 is a right-hand A-STFP indexable boring bar designed for internal turning and boring operations on metalworking lathes and machining centers. Built from steel with a 0.5-inch shank diameter and an 8-inch overall length, this bar accepts TP.. 21.51 inserts held in place by a screw-clamping method. The through-coolant design delivers cutting fluid directly to the cutting zone via a 1/16-27 NPT coolant port, helping control heat and extend insert life during deep-bore applications. A neutral rake angle of 0 degrees suits a broad range of workpiece materials and cutting conditions.

This boring bar is suited for shop environments where minimum bore diameter requirements begin at 0.6 inches. It is a single-purpose toolholder intended for right-hand cutting operations on CNC lathes, manual engine lathes, and turning centers. Machinists and tool-and-die professionals working on precision internal diameters will find the screw-lock insert retention and through-coolant capability particularly useful in high-volume production and close-tolerance jobbing work.

Key Features

• Through-coolant design with 1/16-27 NPT port delivers coolant directly to the cutting edge
• Screw-holding insert retention method provides rigid, repeatable insert indexing
• Neutral rake angle (0 degrees) offers broad material compatibility
• Steel shank construction with 0.5-inch diameter and 8-inch overall length
• Compatible with TP.. 21.51 series inserts, 1/4-inch inscribed circle, 3/32-inch thickness

Compatibility

Designed to accept TP.. 21.51 series indexable inserts with a 1/4-inch inscribed circle and 3/32-inch thickness. Intended as an OEM-style replacement or direct toolholder for right-hand A-STFP boring bar setups using the HERTEL insert system.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Before mounting or indexing inserts, confirm the machine spindle is locked and all motion has stopped. Secure the shank in a properly sized boring bar holder or tool block torqued to the machine manufacturer's specifications. Use appropriate insert-handling tools when seating or replacing the TP.. 21.51 inserts to avoid edge chipping and personal injury.
