Accupro ACC-BB2301000G Boring Bar 0.23in Solid Carbide

Product Description

The ACCUPRO ACC-BB2301000G is a solid carbide boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. Built 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 tool life in both interrupted and continuous cutting applications. The right-hand cutting direction and 5/16-inch shank diameter make it a compact, high-performance choice for machinists working in tight bore diameters and shallow depths.

This boring bar is suited for machining operations requiring a minimum bore diameter of 0.23 inches and a maximum bore depth of 1 inch. It is commonly used in job shops, production machining environments, and toolroom applications where small-diameter internal features demand consistent dimensional accuracy. The 2.5-inch overall length keeps overhang manageable, reducing chatter and deflection during the cut. Machinists working with ferrous and non-ferrous materials will find the micrograin carbide substrate appropriate for a wide range of workpiece materials.

Key Features

• Micrograin solid carbide substrate for superior hardness and edge retention
• TiN finish coating reduces cutting friction and extends tool life
• Right-hand cutting direction for standard lathe and boring head setups
• 0.23-inch minimum bore diameter enables work on very small internal features
• 5/16-inch shank diameter fits standard boring bar holders and quick-change tooling
• 2.5-inch overall length limits overhang and minimizes chatter

Compatibility

Designed as a direct-fit replacement or addition for standard boring bar holders and tool blocks accepting a 5/16-inch shank diameter in CNC and manual turning applications.

Installation Notes

Installation is performed by a qualified machinist. Secure the shank fully in the boring bar holder to the manufacturer-specified clamping torque for that holder; do not exceed the minimum bore depth of 1 inch to avoid tool deflection or holder interference. Ensure the machine spindle is fully stopped and locked out before changing or adjusting tooling. Verify tool centerline height alignment before taking a finishing pass to maintain bore geometry.
