Accupro ACC-BBL2301500 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO ACC-BBL2301500 is a solid carbide boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. Built from submicron-grade carbide with a bright finish, it delivers tight dimensional control in small-bore applications. The left-hand cutting direction suits specific spindle configurations and workholding setups. With a minimum bore diameter of 0.23 inches and a maximum bore depth of 1.5 inches, this bar handles fine finish passes and light material removal in small-diameter bores. The 5/16-inch shank diameter and 2.5-inch overall length keep the tool compact for close-tolerance work.

This boring bar is suited for job shops, production machining cells, and tool rooms where small-bore precision work is routine. Left-hand cut geometry makes it appropriate for reverse-spindle operations or specific fixture orientations where a standard right-hand bar cannot reach or produce the required finish. Machinists and CNC operators working with aluminum, steel, and non-ferrous alloys will find the submicron carbide grade and bright coating appropriate for the bore sizes and depths this tool is designed to handle.

Key Features

• Submicron solid carbide construction for rigidity and wear resistance in small-bore applications
• Left-hand cutting direction for reverse-spindle or specialized fixturing setups
• Minimum bore diameter of 0.23 inches suits tight-clearance internal features
• Maximum bore depth of 1.5 inches with a 5/16-inch shank for compact reach
• Bright finish coating reduces built-up edge in non-ferrous and light steel cuts
• 2.5-inch overall length keeps overhang minimal for improved rigidity

Compatibility

Designed as a standard-shank boring bar for use in turning centers, CNC lathes, and manual lathes equipped with tool holders accepting a 5/16-inch round shank boring bar.

Installation Notes

Installation is performed by a qualified machinist or CNC toolroom technician. Ensure the machine spindle is fully stopped and the control is in a safe state before changing tooling. Secure the shank firmly in the boring bar holder to the depth recommended by the holder manufacturer, minimizing overhang to reduce chatter. Verify cutting direction matches spindle rotation before initiating a cut.
