Accupro B100200R Corner Radius Boring Bar Solid Carbide

Product Description

The ACCUPRO B100200R is a corner radius boring bar designed for precision internal boring operations on small-diameter features. Machined from submicron-grade solid carbide, this right-hand cut bar delivers consistent performance in tight-tolerance applications where surface finish and dimensional accuracy are critical. It handles a minimum bore diameter of 0.1 inches and reaches a maximum bore depth of 0.2 inches (13/64 inches). The 1/8-inch shank diameter and 1-1/2-inch overall length make it well suited to CNC lathes and small-bore turning centers. A bright finish coating completes the tool. Corner radius range is 0.003 to 0.005 inches.

This boring bar is used in precision machining environments where small internal diameters must be finished to close tolerances. Typical applications include bore finishing on hydraulic valve bodies, instrument components, small aerospace parts, and similar workpieces requiring fine surface finish and controlled corner geometry. The right-hand cutting direction is standard for conventional CNC lathe spindle rotation. This tool is suited for use by machinists and tool-and-die professionals working on turning centers equipped with 1/8-inch shank toolholders.

Key Features

• Submicron solid carbide construction for wear resistance and edge stability in small-bore applications
• Minimum bore diameter of 0.1 inches enables work on very small internal features
• Maximum bore depth of 0.2 inches (13/64 inches) suits shallow-to-moderate internal passages
• Corner radius range of 0.003 to 0.005 inches for controlled blending at bore transitions
• Bright finish coating reduces built-up edge and aids chip flow
• Right-hand cutting direction compatible with standard CNC lathe spindle rotation

Compatibility

Designed as an OEM-style boring bar for use in toolholders accepting a 1/8-inch round shank, as found on CNC lathes and turning centers configured for small-bore internal turning operations.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for boring bar setup. Power down and lock out the spindle before seating or adjusting the boring bar in the toolholder. Ensure proper shank engagement and clamping torque per the toolholder specification before running the spindle. Inspect the cutting edge for chips or wear before each use, as submicron carbide tools can fracture if run with a damaged edge.
