Accupro ACC-BBL230700 Boring Bar Left Hand Solid Carbide

Product Description

The ACCUPRO ACC-BBL230700 is a solid carbide boring bar designed for left-hand cutting operations on CNC lathes and manual turning centers. Built from submicron-grade solid carbide, it delivers the rigidity and wear resistance needed for tight-tolerance internal bore work. The bar handles a minimum bore diameter of 0.23 inches and a maximum bore depth of 0.7 inches. With a 5/16-inch shank diameter and a 2.5-inch overall length, it fits compact tool holders and is well suited for small-diameter boring applications. Machinists and toolroom operators rely on this type of bar for precision finishing passes in steel, cast iron, and non-ferrous materials.

This boring bar is intended for internal diameter turning and finishing operations in machine shop and production environments. Its left-hand cutting direction makes it appropriate for specific spindle rotation or tool orientation setups where a standard right-hand bar is not suitable. The bright finish coating keeps the cutting surface clean and reduces built-up edge in many common workpiece materials. It is a single-piece, solid-carbide construction with no inserts to index or replace.

Key Features

• Submicron solid carbide construction for rigidity and long tool life
• Left-hand cutting direction for specialized turning setups
• Minimum bore diameter: 0.23 inches
• Maximum bore depth: 0.7 inches
• 5/16-inch shank diameter fits standard small-bore tool holders
• Bright finish coating reduces friction and built-up edge

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide boring bar for small-diameter internal turning applications on CNC and manual lathes accepting a 5/16-inch shank.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Secure the shank firmly in the tool holder to the manufacturer-specified clamping torque for your tool holder make and model. Ensure the spindle and all machine axes are fully stopped and the machine is in a safe state before changing or adjusting tooling. Verify cutting direction and spindle rotation are compatible with the left-hand geometry before initiating a cut.
