Accupro ACC-BB3203000G Boring Bar Solid Carbide Tin

Product Description

The ACCUPRO ACC-BB3203000G is a solid carbide boring bar designed for internal diameter machining on lathes and turning centers. Built from micrograin solid carbide, it delivers the rigidity and edge retention needed for precision bore work in ferrous and non-ferrous materials. A TiN (titanium nitride) finish coating reduces friction and extends tool life between regrinds. With a 0.32 inch minimum bore diameter and a 4 inch overall length, this bar fits applications where close-tolerance internal features are required. Machinists and toolroom professionals install this type of tooling when surface finish and dimensional accuracy inside a bore are critical to part quality.

This boring bar is suited for use on CNC lathes, manual engine lathes, and turning centers in job shop, production, and maintenance-repair environments. The right-hand cutting direction makes it compatible with conventional spindle rotation. A 3/8 inch shank diameter fits standard boring bar holders and quick-change toolposts common in both light-production and precision toolroom settings. Maximum bore depth is 3 inches, making it appropriate for through and blind bore operations in small to medium workpieces. It is packaged and sold as a single unit.

Key Features

• Micrograin solid carbide construction for high rigidity and long cutting edge life
• TiN finish coating reduces friction and increases wear resistance
• 0.32 inch minimum bore diameter allows access to small internal diameters
• 3 inch maximum bore depth supports through and blind bore operations
• 3/8 inch shank diameter fits standard boring bar holders and quick-change toolposts
• Right-hand cutting direction for conventional spindle rotation

Compatibility

Designed as a standard boring bar for use with compatible 3/8 inch boring bar holders and quick-change toolpost systems on lathes and turning centers. No specific machine model compatibility was provided by the manufacturer for this part number.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before inserting or removing the bar from the holder. Ensure the shank is fully seated and clamping screws are properly secured per the toolholder manufacturer's specifications before starting the machine. Inspect the cutting edge for chips or wear before each use, as carbide tooling can fail without visible warning if damaged.
