Horn R105181323TN35 Boring Bar

Product Description

The HORN R105181323TN35 is a boring bar designed for precision internal machining operations. Boring bars are used to enlarge or finish pre-drilled holes to tight dimensional tolerances. This type of tooling is installed in CNC lathes, machining centers, or manual boring mills and is handled by machinists and tooling technicians. The R105181323TN35 weighs 0.05 pounds, making it a compact, lightweight insert-style tool suited for fine-bore applications where rigidity and minimal deflection are critical to achieving consistent results.

Boring bars of this type are used in metalworking environments for both roughing and finishing passes on internal diameters. Typical applications include production machining of valve bodies, hydraulic components, and precision housings. This part is packaged individually and is intended for professional machining operations where tooling selection is matched to specific bore diameters and depth-to-diameter ratios.

Key Features

• Compact and lightweight at 0.05 pounds for reduced tool deflection in tight-bore applications
• Insert-style boring bar design supports repeatable, precise internal diameter machining
• Suitable for use in CNC lathes, machining centers, and manual boring equipment
• Individually packaged for single-unit deployment and tooling inventory management

Compatibility

Designed as an OEM-style replacement or direct-fit boring bar for compatible HORN tooling systems. Verify bore diameter, shank size, and insert geometry against your machine tool specifications before installation.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully powered down and locked out before mounting or changing tooling. Secure the boring bar shank firmly in the tool holder to the manufacturer-recommended clamping method to prevent chatter or pullout during cutting. Follow applicable shop safety procedures and machine tool manufacturer guidelines during setup.
