Accupro B2001200R Corner Radius Boring Bar Solid Carbide

Product Description

The ACCUPRO B2001200R is a corner radius boring bar machined from submicron solid carbide and intended for precision internal boring operations on CNC lathes and manual turning centers. It cuts right-hand direction and accepts a minimum bore diameter of 0.2 inches, reaching a maximum bore depth of 1-13/64 inches (1.2 inches decimal). The 1/4-inch shank diameter and 2-1/2-inch overall length make it well-suited for small-bore work where rigidity and dimensional accuracy are critical. The bright finish coating is applied without additional surface treatment that could alter edge geometry. Machinists and toolroom professionals use this bar when tight corner radii and fine surface finishes are required on internal diameters.

This boring bar is designed for small-diameter internal turning and finishing passes in ferrous and non-ferrous materials. It is a practical choice for production machining environments, toolroom setups, and job-shop applications where bore diameter tolerances are tight and corner geometry must be held consistently. The corner radius range of 0.005 to 0.008 inches suits applications requiring a defined, controlled edge break at the bore floor or shoulder transition rather than a sharp corner.

Key Features

• Submicron solid carbide construction for improved wear resistance and edge stability in small-bore applications
• Corner radius range of 0.005 to 0.008 inches for controlled shoulder and floor geometry
• Minimum bore diameter of 0.2 inches with maximum bore depth of 1-13/64 inches
• 1/4-inch shank diameter for compatibility with standard small-bore toolholders
• 2-1/2-inch overall length balances reach and rigidity in tight bore conditions
• Bright finish coating preserves dimensional accuracy of the cutting edge without added coating buildup

Compatibility

Designed as an OEM-style replacement and standard toolroom boring bar for use in right-hand internal boring operations requiring a 1/4-inch shank and a minimum bore diameter of 0.2 inches.

Installation Notes

Installation and setup should be performed by a qualified machinist familiar with toolholder torque requirements and boring bar overhang guidelines. Secure the shank firmly in the toolholder to minimize deflection and chatter, particularly at maximum bore depth. Power down and lock out the machine spindle before changing or adjusting tooling. Verify bore diameter and depth settings with appropriate gauging before committing to a finish pass.
