Accupro B2301000R Corner Radius Boring Bar Solid Carbide

Product Description

The ACCUPRO B2301000R is a corner radius boring bar designed for precision internal machining operations. Manufactured from submicron solid carbide with a bright finish, this bar delivers the rigidity and wear resistance required for tight-tolerance bore work. It cuts right-hand direction with a minimum bore diameter of 0.23 inches and a maximum bore depth of 1 inch. The 5/16-inch shank diameter and 2.5-inch overall length make it well suited for small-bore applications where reach and stability both matter. Corner radius range runs from 0.005 to 0.008 inches, allowing controlled edge geometry on finished bores.

This boring bar is intended for use in CNC machining centers, manual lathes, and boring mills where small-diameter internal features require precise dimensional control and smooth surface finish. It is a practical choice for machinists working in aerospace, mold-and-die, medical device, and general precision machining environments. The submicron carbide grade performs reliably in both ferrous and non-ferrous materials at production cutting parameters.

Key Features

• Submicron solid carbide construction for extended tool life and dimensional stability
• Right-hand cutting direction for standard boring setups
• Minimum bore diameter of 0.23 inches enables small-bore internal machining
• Corner radius range of 0.005 to 0.008 inches for controlled edge geometry
• Bright finish coating reduces built-up edge in non-ferrous and light ferrous cuts
• 5/16-inch shank diameter with 2.5-inch overall length for compact, rigid setups

Compatibility

Designed as an OEM-style replacement or direct tooling selection for boring bar holders accepting a 5/16-inch round shank, compatible with standard boring head systems used on CNC lathes, machining centers, and manual boring mills.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Secure the shank firmly in the boring bar holder to the holder manufacturer's specified clamping torque before running the spindle. Ensure the machine is fully powered down and the spindle is locked before changing or adjusting tooling. Verify runout with a dial indicator after installation to confirm acceptable concentricity before taking a finishing pass.
