Micro 100 BB-2301000S Solid Carbide Boring Bar 0.230in

Product Description

The MICRO 100 BB-2301000S is a solid carbide boring bar designed for internal diameter machining on lathes and turning centers. It handles a minimum bore diameter of 0.230 inches and reaches a maximum bore depth of 1 inch, making it well suited for small-diameter precision work. The right-hand cutting direction and 5/16-inch shank diameter allow secure tool-post or holder mounting. Solid carbide construction delivers the rigidity and wear resistance needed to hold tight tolerances in ferrous and non-ferrous materials. Overall length is 2.5 inches. Machinists and toolmakers are the primary users of this tool in production and job-shop environments.

This boring bar is used in precision turning and boring operations where small bore diameters must be held to close tolerances. It is appropriate for both production runs and prototype work on manual lathes and CNC turning centers. The compact 2.5-inch overall length suits applications where clearance inside a workpiece or chuck is limited. Right-hand cutting orientation is standard for conventional lathe rotation and fits the majority of internal boring setups encountered in machine shops.

Key Features

• Minimum bore diameter of 0.230 inches for small-bore precision applications
• Maximum bore depth of 1 inch for through and blind-hole boring
• Solid carbide construction for rigidity, wear resistance, and tight tolerance capability
• Right-hand cutting direction compatible with standard lathe rotation
• 5/16-inch shank diameter for secure clamping in common tool holders
• Compact 2.5-inch overall length for use in confined setups

Compatibility

Designed as an OEM-style boring bar for use in tool holders and boring bar holders accepting a 5/16-inch round shank, on manual or CNC lathes and turning centers configured for right-hand internal boring.

Installation Notes

Installation is performed by a qualified machinist. Power down and lock out the lathe spindle before seating or adjusting the boring bar in the tool holder. Ensure the shank is clamped securely with adequate contact length to minimize overhang-related chatter. Follow shop safety practices and machine-specific tooling guidelines when setting cutting parameters.
