Accupro ACC-BB120500 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO ACC-BB120500 is a solid carbide boring bar designed for precision internal boring operations in small-diameter applications. Built from submicron-grade solid carbide, it delivers the rigidity and wear resistance required for tight-tolerance work in metals and hard materials. The bar features a right-hand cutting direction and a 0.1200-inch minimum bore diameter, making it well-suited for fine bore work where standard tooling cannot reach. Overall length is 2 inches with a 3/16-inch shank diameter and a maximum bore depth of 0.5 inches. Machinists and toolroom professionals working on CNC lathes, boring mills, or manual machines will find this bar appropriate for high-precision, small-bore finishing passes.

This boring bar is used in metalworking and machining environments where small internal diameters require accurate, repeatable results. Typical applications include finish boring of valve bodies, hydraulic components, small housings, and precision fixture work. The submicron carbide grade supports use in both ferrous and non-ferrous materials. It is appropriate for job shops, production machining, and toolroom settings where close tolerances on bore diameter and surface finish are required.

Key Features

• Submicron solid carbide construction for high rigidity and extended tool life
• 0.1200-inch minimum bore diameter for small, tight-clearance bore work
• Right-hand cutting direction for standard lathe and boring mill setups
• 3/16-inch shank diameter for compatibility with small-bore toolholders
• Maximum bore depth of 0.5 inches suits shallow precision bore applications
• 2-inch overall length for compact setup in confined machine envelopes

Compatibility

Designed as an OEM-style replacement or direct-fit boring bar for toolholders accepting a 3/16-inch round shank, commonly used in small-bore turning and boring applications on CNC and manual lathes.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the machine spindle is fully stopped and locked out before mounting or removing the boring bar. Secure the shank firmly in the toolholder to the recommended clamping torque specified by the toolholder manufacturer. Verify bore alignment and runout with an indicator before commencing cutting operations.
