Accupro ACC-BB4901000 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO ACC-BB4901000 is a solid carbide boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. Built from submicron-grade solid carbide with a bright finish coating, it delivers consistent cutting performance in tight-tolerance bore applications. The bar accepts a minimum bore diameter of 0.49 inches and reaches a maximum bore depth of 1 inch. With a 0.5-inch shank diameter and an overall length of 3 inches, this right-hand-cut tool suits machinists and toolroom operators working with close-tolerance bores in steel, cast iron, and similar materials.

This boring bar is suited for production and job-shop environments where repeatable bore sizing is required. It fits standard 0.5-inch boring bar holders and tool blocks common on CNC turning centers and manual lathes. The submicron carbide grade provides good edge retention and resistance to chipping under continuous cutting conditions, making it a practical choice for finish boring passes where dimensional accuracy is critical.

Key Features

• Submicron solid carbide construction for edge retention and chipping resistance
• Minimum bore diameter of 0.49 inches for tight internal features
• Maximum bore depth of 1 inch for short to medium-length bore passes
• Right-hand cutting direction for standard lathe rotation
• Bright finish coating for clean chip release and reduced built-up edge
• 0.5-inch shank diameter fits common boring bar holders and tool blocks

Compatibility

Designed for use with standard 0.5-inch boring bar holders on CNC turning centers and manual lathes requiring right-hand internal boring capability.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the shank fully in the boring bar holder with adequate overhang support to minimize vibration and deflection. Ensure the tool is set on center height before taking a cut. Follow machine tool manufacturer guidelines for speed, feed, and depth-of-cut recommendations appropriate to the workpiece material.
