Horn R10518090112T35 Boring Bar Carbide Insert

Product Description

The HORN R10518090112T35 is a carbide boring insert designed for precision internal boring operations in metal cutting applications. This insert mounts in a compatible boring bar holder and provides the cutting edge geometry needed for accurate bore sizing in lathe and machining center work. At 0.006 pounds, it is a compact, single-piece insert suited for production and maintenance machining environments. Installation and tool changes are typically performed by machinists or toolroom technicians working with CNC or manual turning equipment.

This boring insert is used in internal turning and boring operations where tight bore tolerances and surface finish quality are required. It is appropriate for light to medium material removal in steel, cast iron, and similar workpiece materials depending on toolholder setup and cutting parameters. The TH35 designation indicates the insert grade, which is relevant for matching the insert to the correct cutting application and workpiece material group.

Key Features

• Carbide construction for wear resistance in internal boring operations
• TH35 grade designation for targeted application matching
• Compact, lightweight form factor at 0.006 pounds

Installation Notes

Insert replacement and seating should be performed by a qualified machinist or toolroom technician with the machine powered down and all axes locked. Use the correct torque wrench and HORN-specified clamping screw to seat the insert without over-torquing the clamping mechanism. Inspect the insert pocket and seating surface for chips or debris before installing a new insert. Follow applicable shop safety procedures and machine manufacturer guidelines during tooling changes.
