Accupro ACC-BB3602000 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO ACC-BB3602000 is a solid carbide boring bar engineered for precision internal boring operations on CNC lathes and manual turning centers. It handles a minimum bore diameter of 0.36 inches and a maximum bore depth of 2 inches, making it well suited for small-diameter, tight-tolerance work. The submicron carbide grade delivers superior hardness and wear resistance compared to standard carbide grades, supporting consistent surface finishes even at elevated cutting speeds. The bright finish coating reduces friction and helps with chip evacuation. This bar ships individually and is used by machinists and toolroom professionals across manufacturing and job-shop environments.

This boring bar is intended for right-hand cut operations in materials where solid carbide tooling is preferred over steel or inserted-carbide alternatives. Its 3/8-inch shank diameter fits standard boring bar holders and quick-change toolpost systems commonly found on small to mid-size lathes. With a 4-inch overall length, it provides the reach needed for moderate-depth bores without sacrificing rigidity. It is a practical choice for production runs and precision one-off work requiring repeatable bore diameter control.

Key Features

• Submicron solid carbide construction for high hardness and extended tool life
• Minimum bore diameter of 0.36 inches for small-bore applications
• Maximum bore depth of 2 inches suits a wide range of typical turning operations
• Right-hand cut geometry for standard lathe setups
• Bright finish coating reduces friction and aids chip flow
• 3/8-inch shank diameter fits common boring bar holders and quick-change systems

Compatibility

Designed for use in standard boring bar holders accepting a 3/8-inch shank diameter on CNC and manual lathes configured for right-hand internal turning operations.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the shank firmly in the boring bar holder to the full recommended grip depth to minimize overhang and chatter. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing or adjusting tooling. Refer to the machine tool manufacturer guidelines and applicable shop safety procedures when setting tool height and feed rates.
