Accupro B110500R Corner Radius Boring Bar Solid Carbide

Product Description

The ACCUPRO B110500R is a corner radius boring bar ground from submicron solid carbide for precision internal turning and bore-finishing operations. It cuts right hand and handles a minimum bore diameter of 0.11 inches with a maximum bore depth of 0.5 inches. The 1/8-inch shank diameter and 1.5-inch overall length make it suited for small-bore work where rigidity and tight tolerances are critical. The bright, uncoated finish allows direct inspection of the cutting edge and is compatible with a range of cutting fluids. Machinists and tool-and-die professionals use this bar where corner geometry must be held to close tolerances.

This boring bar is designed for small-bore internal machining in CNC lathes and manual turning centers. Typical applications include finishing bores in tooling components, mold inserts, medical parts, and precision mechanical assemblies where a controlled corner radius between 0.003 and 0.005 inches is required. The submicron carbide grade provides the hardness and edge retention needed for ferrous and non-ferrous materials at fine finishing depths of cut.

Key Features

• Submicron solid carbide construction for superior edge retention and rigidity in small bores
• Corner radius range of 0.003 to 0.005 inches for controlled internal geometry
• Minimum bore diameter of 0.11 inches suits tight, small-diameter applications
• Maximum bore depth of 0.5 inches with a 1/8-inch shank diameter
• Bright, uncoated finish for compatibility with a wide range of cutting fluids and easy edge inspection
• Right-hand cutting direction for standard lathe setups

Compatibility

Designed for use in standard 1/8-inch boring bar holders on CNC and manual lathes requiring right-hand internal turning capability in small-diameter bores.

Installation Notes

Installation is performed by qualified machinists familiar with turning center tooling setups. Power down and lock out the machine before seating or removing the boring bar from its holder. Ensure the shank is clamped securely and that tool overhang is minimized to reduce chatter in small-bore applications. Follow the machine manufacturer and shop safety guidelines for tooling changes.
