Accupro ACC-BB320500 Boring Bar Right Hand Solid Carbide

Product Description

The ACCUPRO ACC-BB320500 is a solid carbide boring bar designed for internal diameter boring operations on CNC lathes and manual turning centers. Built from submicron-grade solid carbide with a bright finish, this bar delivers the rigidity and edge retention needed for tight-tolerance bores in ferrous and non-ferrous materials. The right-hand cutting geometry suits standard spindle rotation in most turning applications. With a 3/8 inch shank diameter and 2.5 inch overall length, the ACC-BB320500 fits standard boring bar holders and quick-change tooling systems commonly found in production and job-shop environments.

This boring bar is suited for light to medium internal boring passes in small-diameter bores. The 0.32 inch minimum bore diameter makes it appropriate for close-tolerance work in small parts such as bushings, hydraulic components, and precision fittings. It is typically installed and operated by machinists in CNC lathe setups and manual turning applications where consistent finish and dimensional accuracy are required. Single-piece packaging supports individual tool replacement without overstocking.

Key Features

• Submicron solid carbide construction provides high hardness and wear resistance
• Bright finish reduces built-up edge on non-ferrous and softer ferrous materials
• Right-hand cutting direction compatible with standard CNC and manual lathe spindle rotation
• 0.32 inch minimum bore diameter enables work on small-diameter internal features
• 0.50 inch maximum bore depth suitable for shallow to moderate boring passes
• 3/8 inch shank diameter fits common boring bar holder systems

Compatibility

Designed as an OEM-style solid carbide boring bar for use in standard 3/8 inch boring bar holders on CNC lathes and manual turning centers requiring a right-hand, small-diameter internal boring tool.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Secure the shank firmly in a compatible boring bar holder, ensuring the tool overhang does not exceed recommended length-to-diameter ratios to minimize chatter. Power down and lock out the machine before tool changes per OSHA lockout/tagout procedures. Inspect the cutting edge before each use and replace the bar if chipping or wear is detected, as carbide tools should not be reground in the field without proper grinding equipment.
