Accupro ACC-BB2301150G Boring Bar Solid Carbide Tin

Product Description

The ACCUPRO ACC-BB2301150G is a micrograin solid carbide boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. It accepts a minimum bore diameter of 0.23 inches and reaches a maximum bore depth of 1.15 inches, making it well suited for small-diameter, close-tolerance work. The 5/16-inch shank diameter and 2.5-inch overall length keep the tool compact and rigid. A titanium nitride (TiN) finish coating is applied to the cutting geometry to reduce friction and extend tool life in production environments. Machinists and toolroom professionals install this bar when boring small holes where rigidity and dimensional accuracy are critical.

This boring bar is appropriate for light to medium internal boring passes on steel, aluminum, cast iron, and similar machinable materials. Its right-hand cutting direction suits standard lathe setups where the spindle rotates counterclockwise as viewed from the tailstock. The compact shank and short overall length make it a practical choice for Swiss-style and gang-tool setups, as well as conventional engine lathe work requiring precise bore sizing or finishing passes.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance in small-bore applications
• TiN finish coating reduces friction and extends cutting edge life
• Minimum bore diameter of 0.23 inches for tight-clearance internal work
• Maximum bore depth of 1.15 inches suitable for short, precise bores
• Right-hand cutting direction for standard lathe spindle rotation
• 5/16-inch shank diameter fits common boring bar holders and toolposts

Compatibility

Designed as an OEM-style solid carbide boring bar for use in 5/16-inch boring bar holders on CNC and manual turning centers capable of internal boring operations.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the lathe spindle before securing or removing the boring bar from its holder. Ensure the shank is fully supported in the holder with minimal overhang to reduce chatter and deflection during cutting. Verify tool centerline height before taking the first pass, as off-center height will affect bore geometry and surface finish.
