Accupro ACC-BB230800G Boring Bar Micrograin Solid Carbide Tin

Product Description

The ACCUPRO ACC-BB230800G 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 TiN (titanium nitride) finish coating, this bar delivers consistent cutting performance in tight-tolerance bores. It handles a minimum bore diameter of 0.23 inches and a maximum bore depth of 0.8 inches, making it well suited for small-diameter work where rigidity and edge retention are critical. The right-hand cutting direction is standard for conventional lathe setups. At 0.125 pounds, the bar is lightweight and easy to handle during tool changes.

This boring bar is intended for machining shops, tool and die operations, and production turning environments. It fits standard tool holders with a 5/16-inch shank diameter and is commonly used when boring small features in ferrous and non-ferrous workpieces. The micrograin carbide grade supports work in steel, aluminum, brass, and cast iron. It is a practical choice for machinists running short-run jobs or production runs where hole diameter consistency and surface finish quality are required.

Key Features

• Micrograin solid carbide construction for superior edge retention and rigidity in small-diameter bores
• TiN finish coating reduces friction and extends tool life in ferrous and non-ferrous materials
• Minimum bore diameter of 0.23 inches supports tight, small-bore applications
• Maximum bore depth of 0.8 inches covers typical shallow internal feature requirements
• Right-hand cutting direction for standard lathe and turning center setups
• 5/16-inch shank diameter fits common boring bar holders and turret tooling

Compatibility

Designed as an OEM-style replacement or direct-fit boring bar for standard 5/16-inch shank boring bar holders used in CNC and manual turning center applications.

Installation Notes

Installation is performed by qualified machinists. Power down and de-energize the machine spindle before inserting or removing tooling. Secure the shank firmly in the tool holder to the holder manufacturer's specified clamping procedure to prevent chatter or tool pull-out during the cut. Inspect the cutting edge for chips or wear before each use, as carbide tooling can fracture if run with a damaged edge.
