Accupro ACC-BB120250A Boring Bar Solid Carbide Tialn

Product Description

The ACCUPRO ACC-BB120250A is a micrograin solid carbide boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. It features a TiAlN finish coating that improves heat resistance and extends tool life in ferrous and hardened materials. The minimum bore diameter is 0.12 inches, the maximum bore depth is 0.25 inches, and the overall length is 2 inches. The 3/16-inch shank diameter suits compact tool holders and small-bore applications. This bar is intended for machinists, tool-and-die makers, and CNC operators working to tight tolerances in production or job-shop environments.

This boring bar is suited for small-diameter internal finishing and semi-finishing cuts where dimensional accuracy is critical. The right-hand cutting direction is standard for conventional lathe setups. Its compact geometry makes it well-suited for shallow, tight-bore work in components such as hydraulic fittings, bushings, and precision housings. It is a single-piece, solid-carbide construction with no inserts to index or replace, making setup straightforward and repeatable.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance in demanding cuts
• TiAlN coating improves heat resistance and tool life in ferrous and hardened workpiece materials
• 0.12-inch minimum bore diameter enables accurate machining of small internal diameters
• 0.25-inch maximum bore depth suits shallow-bore finishing and semi-finishing operations
• Right-hand cutting direction compatible with standard lathe configurations
• 3/16-inch shank diameter fits compact and small-bore tool holders

Compatibility

Designed as an OEM-style solid-carbide boring bar for use in CNC lathes and manual turning centers equipped with tool holders accepting a 3/16-inch round shank.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine powered off and in a locked-out state per applicable shop safety procedures. Ensure the shank is secured firmly in the tool holder to the minimum recommended engagement depth to prevent chatter or tool pullout. Do not exceed the rated maximum bore depth of 0.25 inches. Verify tool centerline height before beginning a cut to maintain bore geometry and surface finish quality.
