Accupro ACC-BB490750G Boring Bar Micrograin Carbide Tin

Product Description

The ACCUPRO ACC-BB490750G is a solid carbide boring bar designed for internal boring operations on metalworking lathes and machining centers. It features a micrograin carbide substrate with a TiN finish coating, delivering enhanced wear resistance and edge retention in a compact, rigid body. The bar accepts a minimum bore diameter of 0.49 inches and reaches a maximum bore depth of 0.75 inches, making it well suited for small-bore precision work. The 0.5 inch shank diameter and 3 inch overall length provide a stable platform for tight-tolerance applications. Right-hand cutting geometry is standard. Installation is handled by machinists and toolroom technicians.

This boring bar is intended for use in precision machining environments where small internal diameters and controlled depths are required. It fits standard tool holders with a 0.5 inch shank bore and is appropriate for both production and job shop settings. Typical applications include finish boring of bushings, bearing housings, and similar small-diameter features in ferrous and non-ferrous materials. The TiN coating extends tool life across a range of cutting speeds and materials.

Key Features

• Micrograin solid carbide construction for superior rigidity and wear resistance
• TiN finish coating for extended tool life and reduced friction
• Right-hand cutting direction for standard lathe and machining center setups
• 0.49 inch minimum bore diameter for precise small-bore applications
• 0.5 inch shank diameter compatible with standard tool holders
• 3 inch overall length provides reach with minimal overhang

Compatibility

Designed for use in standard tool holders accepting a 0.5 inch shank diameter; suitable for lathes and machining centers configured for right-hand internal boring operations.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Secure the shank firmly in the tool holder to the manufacturer-specified clamping torque for the holder used, minimizing overhang to reduce chatter. Ensure the machine spindle is fully stopped and the machine is in a safe, locked-out state before mounting or removing the boring bar. Follow applicable shop safety procedures and machine tool manufacturer guidelines when setting cutting parameters.
