Horn R105180511 MG12 Profile Boring Bar Solid Carbide

Product Description

The HORN R105180511 MG12 is a solid carbide profile boring bar designed for internal profile turning and precision bore finishing operations. With a minimum bore diameter of 0.039 inches and a maximum bore depth of 0.236 inches, this bar handles tight, small-diameter bores that require consistent geometry and surface finish. The right-hand cutting direction and 0.004-inch corner radius make it suitable for fine profiling passes in hardened or difficult-to-machine materials. Solid carbide construction in the MG12 grade provides the rigidity and wear resistance required for repeatable results in production environments. Machinists and toolroom technicians working on Swiss-type, CNC turning, or multi-axis machines will find this bar a reliable choice for small-bore applications.

This profile boring bar is intended for small-bore internal machining operations on CNC lathes, Swiss-style machines, and multi-spindle turning centers. It is particularly suited for applications where bore diameter clearance is tight and depth-to-diameter ratios demand a rigid, compact tool. The uncoated solid carbide construction allows for use across a range of workpiece materials including steel, stainless, aluminum, and non-ferrous alloys. Professional machinists and CNC operators in precision manufacturing and job shop environments are the primary users.

Compatibility

Designed as an OEM-style tooling component for small-bore internal profile turning operations on CNC turning centers and Swiss-type machines that accept this shank diameter and overall length configuration.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC toolroom technician. Ensure the machine spindle is fully stopped and the machine is placed in a safe state before mounting or removing any cutting tool. Verify that the shank diameter and overall length are compatible with the tool holder before mounting. Follow the machine tool manufacturer guidelines and applicable shop safety procedures when setting tool offsets and running initial passes.
