Hertel 7000066 Indexable Boring Bar 0.98in Right Hand

Product Description

The HERTEL 7000066 is a right-hand A-SDUP 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 tool accepts DP.. 32.52 style inserts secured by screw clamping. The through-coolant design delivers cutting fluid directly to the cutting zone via a 1/8-27 NPT coolant hole, helping control heat and extend insert life during continuous boring passes. A neutral rake angle and -3-degree lead angle make it well suited for stable, consistent material removal in a variety of bore applications.

This boring bar is intended for use by machinists and toolroom professionals in production and job-shop environments. It handles minimum bore diameters starting at 0.98 inches, making it appropriate for medium-bore internal finishing and semi-finishing work. The 10-inch overall length provides reach for deeper bore applications while the 0.562-inch center-to-cutting-edge and back-of-bar-to-cutting-edge dimensions support accurate setup and offset entry. Insert compatibility is limited to DP.. 32.52 inserts with a 3/8-inch inscribed circle and 5/32-inch thickness. Note: Use insert screw 73575631 and insert wrench 89091243 for proper assembly.

Installation Notes

Installation is performed by qualified machinists following standard toolholder setup procedures for CNC lathes and turning centers. Confirm the machine spindle and turret are fully powered down and locked out before mounting or changing the boring bar. Torque the shank clamp bolts according to the machine tool manufacturer specifications and verify tool offset entry before initiating a cut. Connect the coolant supply line to the 1/8-27 NPT inlet only after confirming thread compatibility with the machine coolant system.
