Horn R105182325 TN35 Profile Boring Bar Solid Carbide Tin

Product Description

The HORN R105182325 TN35 is a solid carbide profile boring bar designed for internal profile turning and boring operations on CNC lathes and turning centers. Built from solid carbide with a TiN finish coating, this bar delivers rigidity and wear resistance in tight-bore applications. It features a minimum bore diameter of 0.197 inches and a maximum bore depth of 0.591 inches, making it well suited for small-diameter internal work. The overall length is 1.1811 inches with a 4.00 mm shank diameter. This tooling is installed and qualified by machinists and CNC setup technicians working in precision turning environments.

This profile boring bar is intended for small-bore internal profiling on CNC turning equipment. It handles right-hand cut operations in applications where bore diameter access is restricted and depth control is critical. The TN35 grade designation indicates a coated carbide substrate appropriate for a range of ferrous and non-ferrous materials. It is used in job shop, production, and precision machining environments where consistent, repeatable bore geometry is required. The 0.008-inch corner radius supports controlled surface finish on internal profiles.

Key Features

• Solid carbide construction for rigidity and resistance to deflection in small-bore applications
• TiN finish coating for improved wear resistance and tool life
• Minimum bore diameter of 0.197 inches for tight-clearance internal work
• Maximum bore depth of 0.591 inches
• Right-hand cut orientation
• 0.008-inch corner radius for controlled internal profile geometry

Compatibility

Designed as a profile boring bar for use in CNC lathes and turning centers that accept a 4.00 mm shank diameter toolholder. Verify toolholder bore and clamping method prior to installation.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the machine is in a safe, locked-out state before mounting or removing any cutting tool. Confirm shank seating and clamping torque per the toolholder manufacturer specifications. Do not exceed the maximum bore depth rating of 0.591 inches, as overhang beyond rated depth increases deflection risk and reduces tool life.
