Horn R105181313TN35 Profile Boring Bar Solid Carbide Tin

Product Description

The HORN R105181313TN35 is a solid carbide profile boring bar designed for precision internal turning and profiling operations on CNC lathes and machining centers. It features a right-hand cutting direction, a minimum bore diameter of 0.118 inches, and a TiN (titanium nitride) finish coating in manufacturer grade TN35. With an overall length of 1.1811 inches and a corner radius of 0.008 inches, this bar is suited for tight-tolerance, small-bore applications where rigidity and dimensional accuracy are critical. It is installed and applied by CNC machinists and tooling technicians working in precision machining environments.

This profile boring bar is intended for small-bore internal profiling work with a maximum bore depth of 0.394 inches. The 2.30 mm shank diameter makes it appropriate for use in toolholding systems sized for micro and miniature boring applications. Typical use cases include precision component machining in aerospace, medical device, and industrial manufacturing where close tolerances on small internal diameters are required. This SKU ships individually and has a minimum order quantity of 2 units.

Key Features

• Solid carbide construction for rigidity and wear resistance in small-bore profiling
• TiN finish coating in grade TN35 for improved surface hardness and tool life
• Right-hand cutting direction for standard CNC lathe and boring applications
• 0.008-inch corner radius for controlled profile geometry and surface finish
• Compact 1.1811-inch overall length suits tight workholding and short-reach setups
• 2.30 mm shank diameter compatible with micro boring toolholding systems

Compatibility

Designed as an OEM-style profile boring bar for use in micro and miniature boring toolholding systems accepting a 2.30 mm shank diameter.

Installation Notes

Installation is performed by qualified CNC tooling technicians. Ensure the machine spindle is fully stopped and all energy is locked out before changing or seating tooling. Verify that the toolholder bore and clamping mechanism are clean and within tolerance for the 2.30 mm shank before seating the bar. Handle solid carbide tooling carefully to avoid chipping the cutting edge during setup.
