Horn R105180900512MG Profile Boring Bar Solid Carbide

Product Description

The HORN R105180900512MG is a solid carbide profile boring bar designed for precision internal machining operations. It delivers a minimum bore diameter of 0.079 inches and a maximum bore depth of 0.354 inches, making it well suited for small-diameter, tight-tolerance bore work. The right-hand cutting direction and uncoated carbide construction provide sharp, consistent cutting performance in a compact form. With a 1/16-inch shank diameter and an overall length of 63/64 inches (0.984 inches), this bar fits tooling setups where space is limited and dimensional accuracy is critical. A corner radius of 0.002 inches allows for precise profile geometry on finished bores.

This profile boring bar is intended for use in CNC lathes, Swiss-type screw machines, and precision turning centers handling small-bore applications. It is well matched to production environments requiring repeatable bore profiles in materials where carbide rigidity reduces deflection and chatter. The compact shank and short overall length make it particularly useful in Swiss-style and sub-spindle operations. This tool is typically selected by machinists and tooling specialists working in precision machining, medical device manufacturing, and instrument-grade component production.

Key Features

• Solid carbide construction provides rigidity and wear resistance in small-bore applications
• Minimum bore diameter of 0.079 inches enables access to tight internal geometries
• Maximum bore depth of 0.354 inches suits through and blind bore profiles
• Right-hand cutting direction for standard lathe and turning center setups
• Corner radius of 0.002 inches supports accurate profile geometry on finished surfaces
• Uncoated finish maintains sharp edge geometry for precision cutting

Compatibility

Designed as an OEM-style replacement and standard tooling option for small-bore profile boring applications in CNC turning centers and Swiss-type lathes accepting a 1/16-inch shank diameter boring bar.

Installation Notes

This boring bar should be installed by a qualified machinist following the machine tool manufacturer's tooling setup guidelines. Ensure the machine spindle is fully stopped and locked out before changing or setting tooling. Verify shank clamp torque specifications per the toolholder manufacturer's requirements, and confirm proper overhang is minimized to reduce deflection at this diameter. Handle carbide tooling carefully to avoid chipping the cutting edge during setup.
