Horn R105181300523TI25 Boring Bar

Product Description

The HORN R105181300523TI25 is a boring bar designed for precision internal turning and machining operations. Boring bars are used to enlarge or finish pre-drilled holes to tight dimensional tolerances. This tool is installed in compatible boring bar holders or turrets on CNC lathes and machining centers. It is suited for metalworking applications where accurate bore diameter and surface finish are required. Machinists and toolroom technicians are the primary users of this tooling component.

This boring bar is applicable to internal diameter machining on CNC turning centers and manual lathes in production and job-shop environments. It is used when boring through or blind holes to achieve precise dimensions and finishes. The compact form factor supports work in confined bore geometries where rigidity and reach must be balanced.

Key Features

• Precision-ground boring bar for internal turning and bore finishing operations
• Lightweight construction at 0.1 pounds for reduced spindle load
• Designed for use in CNC lathe turrets and compatible boring bar holders
• Suitable for through-bore and blind-bore applications

Compatibility

Designed as a direct-fit replacement-style boring bar for use with compatible HORN tooling systems and standard boring bar holder interfaces. Verify holder bore diameter and clamping style before installation.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the CNC program is halted before changing or adjusting tooling. Secure the boring bar to the specified clamping torque indicated in the holder manufacturer documentation. Confirm tool overhang and runout with a dial indicator before commencing a cut.
