Accupro B2301200A Boring Bar 0.23 in Min Bore Solid Carbide

Product Description

The ACCUPRO B2301200A is a right-hand cut solid carbide boring bar designed for precision internal diameter machining. Manufactured from submicron-grade carbide and finished with an AlTiN coating, it delivers high wear resistance and thermal stability in demanding cutting conditions. The bar has a minimum bore diameter of 0.23 inches and a maximum bore depth of 1.2 inches (1-13/64 inches), with a 5/16-inch shank diameter and an overall length of 2.5 inches. It is suited for machinists and toolroom professionals working on CNC lathes and boring mills where tight tolerance work is required.

This boring bar is intended for precision internal turning and boring operations in metalworking environments, including production machine shops and toolrooms. Its submicron carbide construction makes it appropriate for hard or abrasive workpiece materials where standard carbide grades lose edge life prematurely. The compact overall length and shank diameter make it a practical fit for small-bore applications on CNC turning centers and manual lathes.

Key Features

• Submicron solid carbide construction for extended tool life in hard materials
• AlTiN finish coating provides high-temperature and wear resistance
• Minimum bore diameter of 0.23 inches suits small-bore precision work
• Maximum bore depth of 1.2 inches (1-13/64 inches) for deeper reach
• Right-hand cutting direction for standard CNC lathe and boring mill setups
• 5/16-inch shank diameter for compatibility with standard toolholders

Compatibility

Designed as an OEM-style replacement or direct tooling selection for standard 5/16-inch shank boring bar holders used in CNC turning centers and manual lathes performing small-bore internal diameter operations.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for toolholder clamping and overhang. Ensure the machine spindle is fully stopped and the machine is powered down or in a safe state before changing tooling. Minimize shank overhang beyond what the bore depth requires to reduce vibration and deflection. Follow shop safety protocols for handling carbide tooling, as edges are sharp and carbide is brittle.
