Accupro ACC-BB2301000A Boring Bar 0.23 in Solid Carbide

Product Description

The ACCUPRO ACC-BB2301000A 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 TiAlN finish coating, it delivers consistent dimensional accuracy and extended tool life in ferrous and non-ferrous materials. The bar handles a minimum bore diameter of 0.23 inches and a maximum bore depth of 1 inch, making it well suited for small-diameter, tight-tolerance bores. The right-hand cut geometry follows standard tool orientation for most lathe setups. With a 5/16-inch shank diameter and a 2.5-inch overall length, the bar fits standard boring bar holders without modification.

This boring bar is intended for use in production and job-shop machining environments where repeatable bore geometry is required. It is appropriate for residential shop use as well as light industrial turning applications. Machinists and CNC operators working with small-bore components in steel, cast iron, aluminum, and similar materials will find it a direct-fit tooling option for standard right-hand boring cycles. It is sold individually and is packaged as a single unit.

Key Features

• Micrograin solid carbide construction for tight-tolerance boring and long tool life
• TiAlN finish coating improves heat resistance and wear performance at higher cutting speeds
• Right-hand cut geometry compatible with standard lathe and CNC turning setups
• 0.23-inch minimum bore diameter for small-bore internal turning applications
• 5/16-inch shank diameter fits standard boring bar holders without adapter modification
• Compact 2.5-inch overall length reduces overhang and improves rigidity in tight setups

Compatibility

Designed as a right-hand solid carbide boring bar for use in standard boring bar holders accepting a 5/16-inch shank diameter on CNC lathes and manual turning centers.

Installation Notes

Installation is performed by a machinist or CNC tooling technician. The machine spindle must be brought to a full stop and the machine placed in a safe lockout state before mounting or removing any tooling. Ensure the boring bar shank is clamped securely in the holder with sufficient engagement length to minimize deflection. Do not exceed the recommended bore depth of 1 inch for this bar geometry, as excessive overhang increases vibration and risk of tool breakage.
