Micro 100 BB-2301400 Boring Bar Solid Carbide Right Hand

Product Description

The MICRO 100 BB-2301400 is a solid carbide boring bar designed for internal diameter machining on metal lathes and boring mills. It delivers a minimum bore diameter of 0.230 inches and a maximum bore depth of 1.400 inches, making it suited for precision small-bore work where rigidity and dimensional accuracy matter. The 5/16-inch shank diameter and 2.5-inch overall length position this tool for use in CNC and manual turning centers. A 0.006-inch corner radius reduces stress concentration at the cutting edge, supporting consistent surface finish in tight-tolerance bores. Machinists and tool-and-die professionals are the primary users of this type of tooling.

This boring bar is applied in job shop, production machining, and maintenance-repair-operations environments where small internal diameters must be held to close tolerances. It is suited for ferrous and non-ferrous workpieces where a right-hand cutting direction is required. The solid carbide construction provides the stiffness needed to minimize deflection in deep, narrow bores relative to the tool diameter.

Key Features

• Minimum bore diameter of 0.230 inches for small-bore internal machining
• Maximum bore depth of 1.400 inches supports deeper passes without tool change
• Solid carbide construction for rigidity and resistance to deflection
• Right-hand cutting direction for standard lathe and boring mill setups
• 0.006-inch corner radius for controlled surface finish at the cutting edge
• 5/16-inch shank diameter for compatibility with standard boring bar holders

Compatibility

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

Installation Notes

Installation and setup of boring bars should be performed by a qualified machinist familiar with lathe or boring mill operation. Secure the shank fully in the tool holder to the manufacturer-specified grip length before beginning cuts, and ensure the machine spindle is fully stopped before making any tool adjustments. Follow applicable shop safety standards and machine manufacturer guidelines when setting tool overhang and depth of cut. Do not exceed the maximum bore depth of 1.400 inches in a single setup without verifying tool holder rigidity.
