Accupro ACC-BB2301250G Boring Bar Solid Carbide Tin

Product Description

The ACCUPRO ACC-BB2301250G is a solid carbide boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. Built from micrograin solid carbide with a titanium nitride (TiN) coating, it delivers consistent cutting performance in ferrous and non-ferrous materials. The bar handles a minimum bore diameter of 0.23 inches and a maximum bore depth of 1.25 inches, making it well suited for small-diameter, close-tolerance bore work. With a 5/16-inch shank diameter and an overall length of 2.5 inches, it mounts compactly in standard boring bar holders. Right-hand cut geometry is configured for conventional lathe rotation. Machinists and toolroom technicians working on precision components rely on this bar for repeatable bore sizing and finish quality.

This boring bar is intended for production and toolroom environments where small-bore accuracy is critical. It is appropriate for use on CNC turning centers, manual lathes, and boring mills equipped with appropriate toolholding. The compact overall length of 2.5 inches and 5/16-inch shank make it compatible with small-bore toolholding setups. Right-hand cutting direction suits standard spindle rotation applications in most shop configurations.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance in precision boring
• TiN coating reduces friction and extends cutting edge life
• Minimum bore diameter of 0.23 inches for small-diameter internal work
• Maximum bore depth of 1.25 inches for through and blind bore applications
• 5/16-inch shank diameter fits standard small-bore toolholders
• Right-hand cut geometry for conventional lathe spindle rotation

Compatibility

Designed as an OEM-style replacement and standard toolroom boring bar for use in CNC and manual turning equipment with toolholding capable of accepting a 5/16-inch shank diameter boring bar.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the lathe or turning center spindle is fully stopped and the machine is in a safe, locked-out state before mounting or removing the boring bar. Seat the shank fully in the toolholder and tighten set screws to the toolholder manufacturer specifications. Verify boring bar runout and overhang before beginning a cut, as excessive overhang beyond rated bore depth can cause chatter and premature tool failure.
