Horn R105181333 TN35 Boring Bar

Product Description

The HORN R105181333 TN35 is a boring bar designed for precision internal turning and boring operations on metal workpieces. Boring bars are used to enlarge or finish pre-existing holes to tight dimensional tolerances. This tool fits into compatible toolholding systems and is installed by machinists and tool-and-die professionals working on CNC or manual lathes. At 0.025 pounds, the bar is a compact, lightweight cutting tool suitable for fine boring passes where rigidity and accurate fit are critical to the finished bore diameter.

This boring bar is suited for internal machining applications in production and job-shop environments. It is typically used when a drilled or rough-bored hole requires accurate sizing, improved surface finish, or tighter roundness. The UNSPSC code 23241601 classifies this as a cutting tool component. It is sold individually per package, with a minimum order quantity of 2 units.

Installation Notes

Boring bars are installed by qualified machinists following standard toolroom practices. Ensure the machine spindle is fully stopped and power is isolated before changing or seating the bar in the toolholder. Secure the bar to the specified clamping torque for the toolholding system as documented by the machine or toolholder manufacturer. Do not exceed the recommended overhang length for the bar diameter, as excessive overhang increases deflection and chatter risk.
