Accupro ACC-BB230800A Boring Bar Solid Carbide Tialn

Product Description

The ACCUPRO ACC-BB230800A is a solid carbide boring bar designed for internal diameter machining on CNC lathes and manual turning centers. Manufactured from micrograin solid carbide, it delivers the rigidity and edge retention needed for tight-tolerance bore work. The bar accepts a minimum bore diameter of 0.23 inches and reaches a maximum bore depth of 0.8 inches. A TiAlN finish coating improves heat resistance and extends tool life in ferrous and hardened materials. The 5/16-inch shank diameter fits standard boring bar holders, and the 2.5-inch overall length suits compact tooling setups. Machinists and CNC operators working in job shops or production environments are the primary users.

This boring bar is suited for small-diameter internal turning operations in both light and medium-duty cutting applications. The right-hand cutting direction makes it compatible with conventional lathe rotation setups. It is a practical choice for shops boring valve bodies, hydraulic fittings, small housings, or other components requiring precise internal diameters in the 0.23-inch range. The micrograin carbide grade supports consistent performance in steel, cast iron, and similar workpiece materials.

Key Features

• Micrograin solid carbide construction for rigidity and sharp edge retention
• TiAlN finish coating for improved heat resistance and extended tool life
• 0.23-inch minimum bore diameter for small-diameter internal turning
• 0.8-inch maximum bore depth supports typical short-bore applications
• Right-hand cutting direction for standard lathe rotation
• 5/16-inch shank diameter fits common boring bar holders

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for standard 5/16-inch boring bar holders used in CNC and manual turning center setups.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and the control is in an e-stop or locked-out state before changing tooling. Secure the shank firmly in the boring bar holder to the holder manufacturer's specified clamping method to prevent chatter and tool pullout. Verify bore diameter and depth settings with a test cut before running production parts.
