Horn R105181323MG12 Profile Boring Bar Solid Carbide

Product Description

The HORN R105181323MG12 is a solid carbide profile boring bar designed for precision internal profiling operations on CNC lathes and turning centers. It features a minimum bore diameter of 0.118 inches and a maximum bore depth of 0.591 inches, making it well suited for small-diameter, tight-tolerance bores. The right-hand cutting direction and uncoated solid carbide construction provide dimensional stability and wear resistance in demanding machining environments. With an overall length of 1.378 inches and a 0.008-inch corner radius, this bar delivers consistent profile geometry in confined bore applications. Installation and setup are typically performed by CNC machinists and tooling specialists.

This profile boring bar is intended for use in precision turning and boring applications requiring small minimum bore diameters. The 2.30 mm shank diameter suits compact toolholding systems common in Swiss-style and gang-tool lathe configurations. It is appropriate for production environments where repeatable internal profile geometry is required in metals and other machinable materials. The MG12 grade designation indicates the specific carbide substrate selected for this tool geometry.

Compatibility

Designed as an OEM-style replacement or direct-use profile boring bar for CNC lathes and turning centers equipped with toolholding systems accepting a 2.30 mm shank diameter.

Installation Notes

This tooling is installed and qualified by CNC machinists or toolroom technicians. Ensure the machine spindle is fully stopped and the control is in an e-stop or safe state before changing tooling. Verify shank clamp torque and runout with an indicator before committing to a production run. Follow the machine builder guidelines and applicable shop safety procedures when handling carbide tooling.
