Accupro ACC-BB230700A Boring Bar 0.23in Solid Carbide Tialn

Product Description

The ACCUPRO ACC-BB230700A is a micrograin solid carbide boring bar designed for precision internal boring operations on CNC and manual lathes. It cuts in a right-hand direction and accepts a minimum bore diameter of 0.23 inches, making it well suited for tight, small-diameter work where rigidity and tool life are critical. The shank diameter is 5/16 inches with an overall length of 2.5 inches, keeping the setup compact. A TiAlN finish coating adds heat resistance and extends cutting life across a range of workpiece materials. Machinists and toolroom operators working in production or job-shop environments rely on solid carbide construction at this scale for dimensional accuracy and reduced chatter.

This boring bar is appropriate for small-diameter internal boring on ferrous and non-ferrous workpieces in both production and prototype machining environments. It is well matched to CNC turning centers and manual lathes where bore depth is shallow and tight tolerances are required. The 0.7-inch maximum bore depth makes it a practical choice for through-holes and shallow blind bores in parts where concentricity and surface finish are priority concerns. Setup is straightforward for experienced machinists running standard turning or boring cycles.

Key Features

• Micrograin solid carbide construction for rigidity and extended tool life in small-diameter boring
• Minimum bore diameter of 0.23 inches for tight internal work
• Maximum bore depth of 0.7 inches suitable for shallow through-holes and blind bores
• Right-hand cutting direction for standard lathe and turning center setups
• TiAlN finish coating improves heat resistance and wear life
• 5/16-inch shank diameter with 2.5-inch overall length for compact tooling setups

Compatibility

Designed as an OEM-style solid carbide boring bar for use in standard 5/16-inch boring bar holders on CNC turning centers and manual lathes requiring a right-hand, small-diameter boring tool.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Secure the shank fully in the boring bar holder and verify overhang is minimized to reduce deflection. Confirm spindle speed, feed rate, and depth of cut are appropriate for the workpiece material before engaging the cut. Always power down and lock out the machine before changing or adjusting tooling.
