Accupro ACC-BB3601250A Boring Bar Solid Carbide Tialn

Product Description

The ACCUPRO ACC-BB3601250A is a solid carbide boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. Built from micrograin solid carbide and coated with TiAlN, it delivers sharp, consistent cutting performance in ferrous and non-ferrous materials. The right-hand cutting direction suits standard setups without special toolholding adapters. With a minimum bore diameter of 0.36 inches and a maximum bore depth of 1.25 inches, it fits compact bores where high rigidity and chip clearance matter. Machinists and tool-and-die professionals working in production or maintenance environments will find this bar suited to tight-tolerance finish boring work.

This boring bar is sized for small-diameter internal turning and finishing passes in a range of part geometries. The 3/8-inch shank diameter fits standard boring bar holders and quick-change toolpost systems commonly found on bench lathes and CNC turning centers handling smaller workpieces. It is appropriate for job shops, maintenance machining, and production runs where consistent bore quality is required. The 2.5-inch overall length keeps the tool compact and minimizes overhang-related deflection in shallow bore applications.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance in precision boring
• TiAlN finish coating improves heat resistance and extends tool life in dry or light-coolant cutting
• Right-hand cut for standard lathe and turning center setups
• 0.36 inches minimum bore diameter suits small internal features requiring tight tolerances
• 1.25 inches maximum bore depth covers the majority of shallow internal turning applications
• 3/8-inch shank diameter fits common boring bar holders without modification

Compatibility

Designed as an OEM-style replacement or direct tooling selection for standard 3/8-inch boring bar holders used on CNC and manual turning centers handling small-diameter internal boring operations.

Installation Notes

Installation is performed by qualified machinists. Ensure the machine spindle is fully stopped and the lathe is powered down before mounting or adjusting the boring bar. Secure the shank firmly in the toolholder to minimize overhang and reduce deflection during the cut. Verify bore depth and diameter setup against part print tolerances before beginning a production run.
