Horn R105183346 TN35 Profile Boring Bar Solid Carbide

Product Description

The HORN R105183346 TN35 is a solid carbide profile boring bar designed for precision internal boring operations on CNC lathes and turning centers. It features a right-hand cutting direction, a minimum bore diameter of 0.236 inches, and a TiN finish coating that extends tool life in ferrous and non-ferrous machining applications. With an overall length of 1.378 inches and a 4.70 mm shank diameter, this bar is suited for tight-tolerance bore profiles where rigidity and surface finish are critical. Machinists and toolroom professionals install this bar in standard boring bar holders on live-tool or fixed-tool turning setups.

This profile boring bar is used in precision machining environments where small-diameter internal profiles must be held to close tolerances. The 0.236 inch minimum bore capacity makes it appropriate for small-bore work on components such as hydraulic bodies, valve seats, and precision housings. The 0.984 inch maximum bore depth and 0.008 inch corner radius allow for controlled profile geometry in short-run and production turning applications. It is compatible with CNC turning centers and manual lathes equipped with appropriate boring bar toolholders.

Key Features

• Right-hand cutting direction for standard CNC lathe orientation
• Solid carbide construction for rigidity and vibration resistance in small-bore applications
• TiN finish coating improves wear resistance and reduces built-up edge
• 0.236 inch minimum bore diameter for small internal profile work
• 0.008 inch corner radius for controlled profile geometry
• 4.70 mm shank diameter compatible with standard small-bore toolholders

Compatibility

Designed for use in CNC turning centers and lathes equipped with boring bar toolholders sized for a 4.70 mm shank diameter. Verify toolholder bore and clamping method before installation.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine before changing or adjusting tooling. Secure the shank fully within the toolholder to the manufacturer-recommended overhang to minimize deflection. Confirm bore diameter and depth clearances before initiating a cutting cycle.
