Accupro ACC-BB2001000 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO ACC-BB2001000 is a solid carbide boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. Built from submicron-grade carbide with a bright finish coating, it delivers consistent dimensional accuracy in tight-tolerance bores. The bar has a minimum bore diameter of 0.2 inches and a maximum bore depth of 1 inch, making it suited for small-diameter, shallow-bore applications. With a 0.25 inch shank diameter and an overall length of 2.5 inches, it fits standard boring bar holders used in production and job-shop turning environments. Right-hand cut geometry defines the tool orientation for conventional setup.

This boring bar is used in precision turning operations where small-diameter internal bores are required. It is appropriate for ferrous and non-ferrous materials in light to medium cutting conditions. Machinists and tool-and-die professionals working on close-tolerance parts will find the submicron carbide grade suitable for fine finishing passes and semi-finish boring in short-run and production environments. The compact overall length and small shank diameter make it a practical choice for sliding headstock machines, small gang-tool lathes, and similar setups requiring minimal tool overhang.

Key Features

• Submicron solid carbide construction for high wear resistance and edge retention
• Minimum bore diameter of 0.2 inches supports small-diameter internal work
• Maximum bore depth of 1 inch suits shallow-bore applications
• Bright finish coating reduces built-up edge in non-ferrous materials
• Right-hand cut geometry for standard lathe orientation
• Compact 2.5 inch overall length minimizes overhang and vibration

Compatibility

Designed for use in standard 0.25 inch boring bar holders on CNC and manual turning centers configured for right-hand internal boring operations.

Installation Notes

Installation is performed by qualified machinists following standard toolroom practice. Secure the shank firmly in the boring bar holder to the full recommended engagement depth to minimize deflection. Ensure the machine spindle is fully stopped and the machine is in a safe state before changing or adjusting tooling. Verify tool centerline height before taking a first pass to maintain bore geometry.
