Accupro ACC-BB2301250 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO ACC-BB2301250 is a solid carbide boring bar designed for precision internal diameter work on CNC lathes and manual turning centers. It features a 0.23-inch minimum bore diameter and a maximum bore depth of 1.25 inches, making it well suited for small-bore finishing and semi-finishing operations. The bar is ground from submicron-grade solid carbide, which provides superior wear resistance and edge retention compared to standard carbide grades. A bright finish coating reduces friction and aids chip flow in tight bore conditions. The 5/16-inch shank diameter and 2.5-inch overall length make this a compact, rigid tool for close-tolerance work.

This boring bar is intended for machinists and tool-and-die professionals working on precision bores in steel, stainless, cast iron, and non-ferrous materials. The right-hand cutting direction suits standard spindle rotation on most lathes and boring setups. Its compact geometry makes it a practical choice for production shops and job shops running small-diameter internal turning operations where rigidity and repeatability are critical.

Key Features

• Submicron solid carbide construction for extended tool life and consistent edge integrity
• 0.23-inch minimum bore diameter supports tight, small-bore internal turning
• 1.25-inch maximum bore depth suitable for through and blind bore applications
• Right-hand cut orientation for standard lathe spindle rotation
• Bright finish coating reduces cutting friction and aids chip evacuation
• Compact 5/16-inch shank diameter with 2.5-inch overall length for rigid tool setups

Compatibility

Designed as an OEM-style solid carbide boring bar for use in standard boring bar holders and tool blocks accepting a 5/16-inch shank diameter on CNC and manual turning equipment.

Installation Notes

Installation is performed by a machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of chips before mounting. Secure the 5/16-inch shank in a compatible boring bar holder to the manufacturer-specified clamping procedure. Verify runout and bore alignment before taking a finishing pass to maintain tolerance.
