Accupro ACC-BB120600A Boring Bar Solid Carbide Tialn

Product Description

The ACCUPRO ACC-BB120600A is a micrograin solid carbide boring bar designed for precision internal turning and boring operations on CNC lathes and manual turning centers. It features a TiAlN finish coating for improved heat resistance and tool life, a minimum bore diameter of 0.12 inches, and a maximum bore depth of 0.6 inches. The right-hand cutting direction suits standard lathe setups. With a 3/16 inch shank diameter and a 2 inch overall length, this bar is sized for small-bore work requiring tight tolerances and clean finishes. Machinists and toolroom technicians use this type of boring bar in production and job-shop environments.

This boring bar is well suited for small-diameter internal bore finishing and roughing passes in ferrous and non-ferrous materials. The micrograin carbide substrate provides the edge stability needed for fine surface finishes in tight-tolerance applications. Typical installations include CNC turning centers and manual lathes where small-bore access and rigid toolholding are required. The TiAlN coating extends cutting performance in higher-temperature cutting conditions, making it appropriate for harder workpiece materials.

Key Features

• Micrograin solid carbide substrate for superior edge retention and rigidity in small-bore applications
• TiAlN coating provides enhanced heat resistance and extended tool life
• Minimum bore diameter of 0.12 inches for access to small internal features
• Maximum bore depth of 0.6 inches
• Right-hand cutting direction for standard lathe orientation
• 3/16 inch shank diameter with 2 inch overall length for compact toolholding setups

Compatibility

Designed as an OEM-style replacement or direct-fit boring bar for standard boring bar toolholders accepting a 3/16 inch shank diameter.

Installation Notes

Installation and setup should be performed by a qualified machinist familiar with turning tool geometry and toolholder requirements. Ensure the machine spindle is fully stopped and the lathe is powered down before changing or adjusting tooling. Secure the shank firmly in the toolholder to the appropriate clamping specification for the holder in use, minimizing overhang to reduce chatter. Verify cutting direction and tool height before initiating a cut.
