Accupro ACC-BB230700G Boring Bar Right Hand Solid Carbide

Product Description

The ACCUPRO ACC-BB230700G is a solid carbide boring bar designed for precision internal turning and boring operations on CNC lathes and manual turning centers. Constructed from micrograin solid carbide, this bar delivers superior rigidity and wear resistance compared to high-speed steel alternatives. A titanium nitride (TiN) finish coating reduces friction and extends cutting edge life. The bar features a right-hand cutting direction and accepts a minimum bore diameter of 0.23 inches with a maximum bore depth of 0.7 inches. It is suited for machinists and tool-and-die professionals requiring tight tolerances in small-bore applications.

This boring bar is intended for small-bore internal machining on ferrous and non-ferrous workpieces. Its 5/16-inch shank diameter and 2.5-inch overall length make it compatible with standard boring bar holders and quick-change toolposts found on most bench lathes and CNC turning centers. It is a practical choice for production shops and job shops where consistent bore finish and dimensional accuracy are required on short, tight-bore features.

Key Features

• Micrograin solid carbide construction for rigidity and long tool life
• TiN finish coating reduces friction and improves wear resistance
• Right-hand cutting direction for standard lathe setups
• 0.23-inch minimum bore diameter suits small-bore internal turning
• 0.7-inch maximum bore depth for short, precise bore features
• 5/16-inch shank diameter fits standard boring bar holders

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for standard boring bar holders with a 5/16-inch bore, used on manual and CNC turning centers requiring right-hand internal boring capability.

Installation Notes

Installation is performed by a machinist or toolroom technician. Secure the shank firmly in the boring bar holder to the tool manufacturer's recommended clamping specification, ensuring minimal overhang to reduce chatter. Power down and lock out the spindle before changing or adjusting tooling. Verify bore clearance before beginning the cut to avoid tool or workpiece damage.
