Accupro ACC-BB230800 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO ACC-BB230800 is a solid carbide boring bar designed for precision internal diameter boring on CNC lathes and manual turning centers. Manufactured from submicron-grade carbide with a bright finish, it delivers consistent cutting performance in tight-tolerance bore applications. The bar accepts a minimum bore diameter of 0.23 inches and reaches a maximum bore depth of 0.8 inches, making it well suited for small-diameter work where rigidity and surface finish are critical. The right-hand cutting direction and 5/16-inch shank diameter allow straightforward setup in standard tool holders. Machinists and toolroom technicians working in production or job-shop environments will find this bar a reliable choice for finishing and semi-finishing passes.

This boring bar is intended for use in metalworking applications requiring precise internal bore sizing. It is appropriate for small-bore work in materials where submicron carbide grade provides the necessary hardness and wear resistance. The 2.5-inch overall length keeps the tool compact, reducing deflection during cuts. Typical applications include component finishing on CNC turning centers, manual lathes, and production machining cells handling close-tolerance bores in the 0.23-inch range and above.

Key Features

• Submicron solid carbide construction for extended tool life and consistent edge integrity
• Minimum bore diameter of 0.23 inches suited for small-diameter internal turning
• Maximum bore depth of 0.8 inches provides adequate reach for typical short-bore work
• Right-hand cutting direction compatible with standard lathe spindle rotation
• Bright finish coating reduces built-up edge and aids chip flow
• Compact 2.5-inch overall length minimizes overhang and tool deflection

Compatibility

Designed as an OEM-style solid carbide boring bar for use in standard 5/16-inch shank tool holders on CNC and manual turning equipment handling small-diameter internal bore operations.

Installation Notes

Installation should be performed by a qualified machinist familiar with turning tool setup procedures. Secure the shank firmly in the tool holder to the minimum recommended overhang to reduce vibration and deflection during the cut. Ensure the machine spindle is fully stopped and the lathe is locked out before mounting or adjusting the bar. Verify tool height alignment to centerline before starting any boring operation.
