Micro 100 BB-2301500X Boring Bar 0.230 in Solid Carbide

Product Description

The MICRO 100 BB-2301500X is a solid carbide boring bar designed for internal diameter machining in precision metalworking applications. It features a minimum bore diameter of 0.230 inches and a maximum bore depth of 1-1/2 inches, making it well-suited for small-hole boring work where rigidity and dimensional accuracy matter. The 5/16-inch shank diameter provides secure tool holding, while the 0.0060-inch corner radius supports clean, controlled cuts at tight tolerances. Solid carbide construction delivers the hardness and wear resistance required for consistent performance across production and job-shop environments.

This boring bar is intended for use in CNC turning centers, manual lathes, and boring mills where small-diameter internal features must be machined to close tolerances. The right-hand cutting direction suits standard spindle rotation setups. With an overall length of 2-1/2 inches, it fits a range of tool holders and turrets commonly used in precision machining operations. Machinists and toolroom professionals working in aerospace, medical device, and general manufacturing applications will find this bar suited to fine finishing and light roughing passes in bores starting at 0.230 inches.

Key Features

• Solid carbide construction for high rigidity and extended tool life
• Minimum bore diameter of 0.230 inches for small-hole internal machining
• Maximum bore depth of 1-1/2 inches
• 5/16-inch shank diameter for secure clamping in standard tool holders
• 0.0060-inch corner radius for controlled surface finish and tight tolerance work
• Right-hand cutting direction compatible with standard spindle rotation

Compatibility

Designed as an OEM-style replacement and standard tooling option for lathes, CNC turning centers, and boring mills equipped with tool holders accepting a 5/16-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist familiar with tool holder setup and cutting parameter selection. Secure the shank firmly in the tool holder to the full recommended clamping engagement before beginning a cut. Power down and lock out the machine spindle before installing or removing the boring bar. Do not exceed the maximum bore depth rating of 1-1/2 inches, as overhang beyond rated depth increases deflection risk.
