Horn R105183336 TN35 Profile Boring Bar Solid Carbide

Product Description

The HORN R105183336 TN35 is a solid carbide profile boring bar designed for internal profiling operations on CNC lathes and turning centers. Built for right-hand cutting, it features a TiN finish coating and a 0.008-inch corner radius, making it suitable for precise, repeatable bore profiling in tight bores starting at 0.236 inches minimum diameter. With an overall length of 1.5748 inches and a 4.70 mm shank diameter, this bar is engineered for compact internal turning applications where rigidity and dimensional accuracy are critical. It is installed and operated by machinists and CNC turning professionals working in production or job-shop environments.

This boring bar is suited for internal profile turning in small-bore components such as hydraulic fittings, medical parts, aerospace components, and precision mechanical assemblies. The right-hand cutting direction and solid carbide construction make it appropriate for ferrous and non-ferrous materials where consistent finish and bore geometry are required. Maximum bore depth is 0.787 inches, keeping the tool within its designed deflection limits during cuts.

Key Features

• Solid carbide construction provides rigidity and wear resistance in small-bore applications
• TiN finish coating extends tool life and reduces friction at the cutting edge
• 0.236-inch minimum bore diameter allows profiling in very small internal diameters
• 0.008-inch corner radius supports controlled profile geometry and surface finish
• Right-hand cut orientation for standard CNC turning center setup
• Manufacturer grade TN35 designation identifies the carbide substrate and coating specification

Compatibility

Designed as an OEM-specification profile boring bar for use in CNC turning centers and lathes accepting a 4.70 mm shank diameter toolholder.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in an e-stop or locked-out state per OSHA lockout/tagout procedures. Confirm shank seating and toolholder clamping torque per the toolholder manufacturer specifications before running. Do not exceed the maximum bore depth of 0.787 inches, as overhang beyond design limits increases deflection and risks tool breakage. Inspect the cutting edge for chipping or wear before each use.
