Hertel H59868349 Indexable Boring Bar Solid Carbide

Product Description

The HERTEL H59868349 is a solid carbide indexable boring bar designed for precision internal turning and bore finishing operations on CNC lathes and manual turning centers. It carries the HBBC toolholder style designation and accepts CD-type inserts secured by a screw clamping method. With a minimum bore diameter of 0.18 inches and a maximum bore depth of 1.5625 inches, this bar is suited for small-diameter, deep-reach boring work where rigidity and dimensional accuracy are critical. The solid carbide construction delivers the stiffness needed to minimize deflection in tight-bore applications. Coolant-through capability supports chip evacuation and tool life in production environments.

This boring bar is used in metalworking operations requiring precise internal diameter control in small-bore workpieces. The right-hand cut orientation is standard for conventional lathe setups. Its 5/32-inch shank diameter and 6-inch overall length make it appropriate for use in small-to-medium turning centers and dedicated boring fixtures. Machinists, toolroom operators, and CNC turning specialists working in job shops or production facilities are the typical installers and users of this tooling.

Key Features

• Solid carbide construction for high stiffness and reduced deflection in small-bore applications
• Minimum bore diameter of 0.18 inches enables machining of tight internal diameters
• Maximum bore depth of 1.5625 inches for reach into deeper bores
• Screw-lock insert holding method provides secure, repeatable insert indexing
• Coolant-through design supports chip removal and extends insert life
• Right-hand cut orientation for standard lathe tool post setups

Compatibility

Designed to accept CD-style indexable inserts. No specific machine model compatibility is stated in the available product data. Confirm shank diameter and insert type against your tool block or turret specification before ordering.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is stopped and the turret or tool post is in a safe, locked position before mounting or indexing inserts. Use the appropriate torque wrench and screw driver to seat the insert screw — do not overtighten. Verify boring bar runout and overhang within the toolholder before taking initial cuts.
