Hertel H59868729 Indexable Boring Bar 0.23 in Right Hand

Product Description

The HERTEL H59868729 is a solid carbide indexable boring bar designed for internal turning and bore finishing operations on CNC lathes and boring machines. Built to the HBBC toolholder style, it features a 0.5 inch shank diameter and a 2.5 inch overall length, making it suitable for small-bore precision work. The insert is secured by a screw-clamp holding method for rigid, repeatable positioning. With a minimum bore diameter of 0.23 inches and a maximum bore depth of 1 inch, this bar is engineered for tight-tolerance applications where tool rigidity and insert stability are critical. Coolant-through capability supports chip evacuation and heat management during high-speed cuts.

This boring bar is intended for use in metal-cutting environments requiring access to small-diameter bores. It is typically installed by machinists and toolroom technicians in production or job-shop settings on manual or CNC turning centers. The right-hand cut orientation suits standard spindle rotation setups. It accepts CD-style inserts, allowing grade and geometry selection to match the workpiece material and surface finish requirement.

Installation Notes

Installation should be performed by a qualified machinist following standard toolroom procedures. Ensure the machine spindle is fully stopped and the tool turret or holder is locked out before mounting or removing the bar. Verify shank clamp torque per the machine tool manufacturer specifications. Confirm insert seating and screw engagement before running at cutting speed.
