Accupro B2001300R Corner Radius Boring Bar Solid Carbide

Product Description

The ACCUPRO B2001300R is a corner radius boring bar designed for precision internal machining operations. Made from submicron solid carbide with a bright finish, it delivers consistent performance in tight-tolerance bore work. The bar handles a minimum bore diameter of 0.2 inches and a maximum bore depth of 1.3 inches, with a corner radius range of 0.005 to 0.008 inches. The 1/4-inch shank diameter and 2.5-inch overall length make it well-suited for small-bore applications in CNC machining centers and manual lathes. Machinists and tool and die professionals install this bar when fine corner geometry control is required in a bore.

This boring bar is used in precision machining environments where corner radius control inside a bore is critical. Typical applications include die and mold work, precision part manufacturing, and finishing operations on small-diameter internal features. The right-hand cutting direction suits standard spindle rotation setups. The submicron carbide grade supports interrupted cuts and hard materials where a tougher grain structure reduces chipping and extends tool life in production or job-shop settings.

Key Features

• Submicron solid carbide construction for improved toughness and wear resistance in small-bore applications
• Corner radius range of 0.005 to 0.008 inches for controlled internal geometry
• Minimum bore diameter of 0.2 inches allows use in tight internal features
• Maximum bore depth of 1.3 inches supports deeper internal passes without tool change
• Bright finish coating reduces friction and aids chip evacuation
• Right-hand cut compatible with standard CNC and manual lathe setups

Compatibility

Designed as a standard 1/4-inch shank boring bar for use in compatible tool holders, boring heads, and machining center setups that accept this shank diameter and right-hand cutting tools.

Installation Notes

Installation is performed by qualified machinists following shop safety procedures. Power down and de-energize the machine spindle before mounting or removing the boring bar. Secure the shank firmly in a compatible tool holder to the appropriate clamping specification for the holder used. Verify bore depth and corner radius requirements against the workpiece drawing before initiating a cut.
