Accupro ACC-BB100700G Boring Bar Micrograin Carbide Tin

Product Description

The ACCUPRO ACC-BB100700G is a solid carbide boring bar designed for precision internal boring operations on CNC and manual lathes. Built from micrograin carbide with a titanium nitride (TiN) coating, it delivers extended tool life and improved surface finish in ferrous and non-ferrous materials. The right-hand cutting configuration suits standard spindle rotation setups. With a minimum bore diameter of 0.1 inches and a maximum bore depth of 0.7 inches, this bar handles tight, shallow bores where rigidity and concentricity are critical. Machinists and toolroom technicians select this bar for close-tolerance work requiring consistent chip clearance and minimal deflection.

This boring bar is suited for small-diameter internal turning and boring applications on production and job-shop equipment. The 0.125-inch shank diameter fits standard boring bar holders and quick-change tooling systems sized for that shank. It is appropriate for finishing passes on bores where dimensional accuracy and surface finish are the primary requirements. The 1.5-inch overall length keeps overhang short, which reduces chatter and maintains accuracy in confined bore geometries.

Key Features

• Micrograin solid carbide construction for high rigidity and wear resistance
• TiN coating extends cutting edge life and reduces built-up edge
• Right-hand cut for standard lathe spindle rotation
• 0.1-inch minimum bore diameter for tight internal features
• 0.7-inch maximum bore depth suitable for shallow blind and through bores
• Short 1.5-inch OAL minimizes overhang and chatter

Compatibility

Designed as a direct-fit boring bar for standard boring bar holders and quick-change toolpost systems accepting a 0.125-inch shank diameter.

Installation Notes

Installation is performed by a machinist or toolroom technician. Secure the shank fully in the boring bar holder to the manufacturer-specified clamping depth before engaging the workpiece. Power down and lock out the machine spindle before changing or adjusting tooling. Confirm bore alignment and runout with an indicator before taking finishing passes to avoid scrap.
