Accupro B230600R Corner Radius Boring Bar Solid Carbide

Product Description

The ACCUPRO B230600R is a corner radius boring bar designed for precision internal boring operations on CNC and manual lathes. Machined from submicron solid carbide, this right-hand-cut tool delivers consistent dimensional accuracy in tight-tolerance bores. It has a minimum bore diameter of 0.23 inches and a maximum bore depth of 0.6 inches. The bright finish coating reduces built-up edge and improves chip evacuation. With a 5/16-inch shank diameter and an overall length of 2.5 inches, it fits standard boring bar holders common in production and job-shop environments. Machinists use this bar for finishing passes where a defined corner radius is required at the base of a bore.

This boring bar suits applications in ferrous and non-ferrous machining where a controlled corner radius between 0.005 and 0.008 inches is specified on the workpiece. It is appropriate for residential and light industrial CNC turning centers, manual lathes, and boring mills. Typical use cases include finishing bores in housings, bushings, and precision mechanical components where sharp corners must be replaced with a radiused transition for stress relief or assembly fit.

Key Features

• Submicron solid carbide construction for rigidity and wear resistance in precision boring
• Right-hand cutting direction for standard lathe and CNC turning setups
• Minimum bore diameter of 0.23 inches supports small-diameter internal operations
• Maximum bore depth of 0.6 inches for controlled depth finishing passes
• Corner radius range of 0.005 to 0.008 inches for defined radiused transitions at bore base
• Bright finish coating reduces friction and chip adhesion during cutting

Compatibility

Designed as an OEM-style replacement and standard tooling option for boring bar holders accepting a 5/16-inch shank diameter in CNC turning centers and manual lathes.

Installation Notes

Installation should be performed by a qualified machinist familiar with boring bar setup and toolholder torque procedures. Ensure the machine spindle is fully stopped and locked out before changing tooling. Confirm shank diameter matches the boring bar holder bore before securing. Do not exceed the maximum bore depth rating of 0.6 inches to avoid deflection or tool breakage.
