Horn R105181934 TN35 Profile Boring Bar Solid Carbide

Product Description

The HORN R105181934 TN35 is a solid carbide profile boring bar designed for precision internal turning and profiling operations in small-bore applications. Built with a TiN finish coating and a 0.008-inch corner radius, this bar delivers tight, repeatable geometry in confined bores. The right-hand cutting direction and 0.157-inch minimum bore diameter make it well suited for fine-detail work in small cavities. With an overall length of 1.378 inches and a 2.90 mm shank diameter, the bar is compact and rigid. Machinists and toolroom professionals use this style of bar in CNC turning centers and manual lathes where bore access and profile accuracy are critical.

This profile boring bar is intended for small-bore internal profiling work where access diameter is limited to 0.157 inches or greater, with a maximum bore depth of 0.787 inches. The right-hand cut orientation suits standard spindle rotation setups common in production and toolroom environments. The TiN coating helps reduce friction and extend tool life when cutting ferrous and non-ferrous materials. It is sold individually per package, with a minimum order quantity of 2 units.

Key Features

• Solid carbide construction for rigidity and dimensional stability in small-bore applications
• TiN finish coating reduces friction and supports extended tool life
• 0.157-inch minimum bore diameter for access in tight internal profiles
• 0.787-inch maximum bore depth provides reach for typical small-bore profiling tasks
• 0.008-inch corner radius for controlled profile blending and sharp feature definition
• Right-hand cutting direction compatible with standard CNC and manual lathe setups

Compatibility

Designed as an OEM-style replacement or direct-use profile boring bar for CNC turning centers and manual lathes requiring a right-hand, solid carbide boring bar with a 2.90 mm shank diameter and 0.157-inch minimum bore capability.

Installation Notes

Installation of boring bars should be performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before mounting or removing the bar from the tool holder. Ensure the shank is seated fully and the holder is torqued to the machine manufacturer's specification using calibrated tooling. Verify bore clearance and cutting direction before initiating a cut to prevent tool damage or workpiece scrap.
