Accupro ACC-BB320600G Boring Bar Solid Carbide Tin

Product Description

The ACCUPRO ACC-BB320600G is a solid carbide boring bar designed for precision internal diameter machining on CNC lathes and manual turning centers. Built from micrograin solid carbide stock, this bar delivers consistent cutting performance and extended tool life in ferrous and non-ferrous materials. A titanium nitride (TiN) finish coating reduces friction and improves wear resistance at the cutting edge. With a 0.32 inch minimum bore diameter and a 3/8 inch shank diameter, this bar fits standard boring bar holders and quick-change tooling systems commonly used in production and job-shop turning operations. It is installed and set up by machinists and toolroom technicians.

This boring bar is suited for small-diameter internal turning, finish boring, and light roughing passes where tight tolerances are required. The right-hand cutting direction makes it compatible with conventional lathe spindle rotation. The 2.5 inch overall length and 0.6 inch maximum bore depth suit shallow-bore applications in workpieces held in chucks or collet fixtures. Typical use cases include bore sizing, cleanup passes after drilling, and finishing bored features to close dimensional tolerances in production machining environments.

Key Features

• Micrograin solid carbide construction for rigidity and fine surface finish capability
• TiN finish coating reduces edge wear and built-up edge in common workpiece materials
• 0.32 inch minimum bore diameter suits small internal diameter applications
• Right-hand cutting direction for standard lathe spindle rotation
• 3/8 inch shank diameter fits widely available boring bar holders and tooling blocks
• 0.6 inch maximum bore depth appropriate for shallow through and blind bore work

Compatibility

Designed as an OEM-style replacement and standard tooling option for 3/8 inch boring bar holders used in conventional and CNC turning centers performing small-diameter internal boring operations.

Installation Notes

Installation and tool setup should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before loading or adjusting the boring bar in the holder. Ensure the shank is fully seated and clamped securely in the boring bar holder to minimize overhang and reduce chatter. Follow the machine tool manufacturer guidelines for tool offset entry and test cuts before running to final dimension.
