Horn R105103336TH35 Profile Boring Bar Solid Carbide

Product Description

The HORN R105103336TH35 is a solid carbide profile boring bar designed for internal turning and profiling operations on CNC lathes and boring machines. It features a 0.236-inch minimum bore diameter and a 0.787-inch maximum hole depth, making it well suited for small-diameter internal work where rigidity and precision are critical. The right-hand cut geometry directs cutting forces appropriately for standard spindle rotation. With an overall length of 0.984 inches and a shank diameter of 0.2126 inches, this bar is built for close-tolerance applications. A 0.008-inch corner radius provides a controlled surface finish on profiled bores. Solid carbide construction resists deflection and delivers consistent tool life in both ferrous and non-ferrous materials.

This profile boring bar is intended for use in precision machining environments, primarily in production and job-shop settings operating CNC turning centers or manual lathes equipped for small-bore internal work. It is suited for applications requiring repeatable internal profiles, undercuts, or contour boring where minimum bore diameter access is a constraint. Machinists and tooling specialists working with tight tolerances in small-diameter bores will find this bar appropriate for those demands. Sold individually per package with a minimum order quantity of 2 units.

Key Features

• Solid carbide construction for maximum rigidity and minimal deflection in small-bore applications
• 0.236-inch minimum bore diameter for access in tight internal geometries
• 0.787-inch maximum hole depth supports through and blind bore profiling
• Right-hand cut geometry for standard spindle rotation compatibility
• 0.008-inch corner radius for controlled surface finish on profiled internal features
• 0.2126-inch shank diameter fits standard small-bore toolholders

Compatibility

Designed as a direct-fit profile boring bar for CNC turning centers and manual lathes accepting a 0.2126-inch shank diameter with right-hand internal tooling configurations.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the machine is placed in an appropriate lockout state before mounting or removing tooling. Secure the shank in a compatible boring bar holder to the toolholder manufacturer's recommended clamping method, verifying centerline alignment before operation. Do not exceed the maximum hole depth specification to avoid tool overhang-related deflection or breakage.
