Accupro ACC-BB140700A Boring Bar Micrograin Solid Carbide

Product Description

The ACCUPRO ACC-BB140700A is a solid carbide boring bar designed for precision internal turning and boring operations on CNC and manual lathes. Built from micrograin solid carbide with a TiAlN finish coating, this bar delivers the wear resistance and edge stability required for tight-tolerance work in hardened steels, cast iron, and similar difficult-to-machine materials. The right-hand cutting direction suits standard lathe setups. With a 3/16-inch shank diameter and 2-inch overall length, this is a compact tool sized for small-bore applications starting at 0.14 inches minimum bore diameter and reaching up to 0.7 inches maximum bore depth. Machinists and toolroom technicians installing this bar will find it well suited to production and job-shop environments requiring consistent, repeatable bore finishes.

This boring bar is intended for small-diameter internal boring operations where rigidity and carbide grade matter most. Its compact geometry makes it a practical choice for close-tolerance bores in small workpieces, fixtures, and components where high-speed steel tooling lacks sufficient rigidity or heat resistance. The TiAlN coating extends tool life in dry or minimal-lubrication cutting conditions. This tool is sold individually and is appropriate for use in both production CNC turning centers and manual engine lathes equipped with appropriate tool holders accepting a 3/16-inch round shank.

Key Features

• Micrograin solid carbide construction for superior edge strength and wear resistance
• TiAlN finish coating for extended tool life in ferrous and hard materials
• Right-hand cut orientation for standard lathe boring setups
• 0.14-inch minimum bore diameter enables access to very small internal features
• 0.7-inch maximum bore depth supports typical small-part boring requirements
• 3/16-inch shank diameter fits standard small-bore tool holders

Compatibility

Designed for use in tool holders accepting a 3/16-inch round shank boring bar on CNC turning centers and manual lathes configured for right-hand internal boring operations.

Installation Notes

Installation and tool changes should be performed only with the machine spindle fully stopped and locked out per applicable machine safety procedures. Secure the shank firmly in the tool holder to the appropriate clamping torque specified by the tool holder manufacturer, using the holder manufacturer's instructions rather than values from this listing. Verify boring bar overhang does not exceed manufacturer-recommended length-to-diameter ratios to prevent chatter and tool deflection. Consult your machine tool documentation and applicable shop safety standards before beginning setup.
