Accupro ACC-BB200800G Boring Bar Solid Carbide Tin

Product Description

The ACCUPRO ACC-BB200800G is a solid carbide boring bar designed for precision internal boring operations on CNC and manual lathes. Built from micrograin carbide stock and finished with a titanium nitride (TiN) coating, this bar delivers consistent cutting performance and extended tool life in ferrous and non-ferrous materials. It features a right-hand cutting direction, a 0.25-inch shank diameter, and an overall length of 2.5 inches. The minimum bore diameter is 0.2 inches and the maximum bore depth is 0.8 inches, making it well suited for small-diameter bore work where rigidity and chip clearance are critical. Machinists and tool-and-die professionals are the primary users of this tool.

This boring bar is intended for small-bore internal turning applications in production and job-shop environments. The compact shank diameter and short overall length make it a practical choice for tight clearances and small-part machining on manual lathes, CNC turning centers, and gang-tooled setups. The TiN coating reduces built-up edge and extends cutting intervals between resharpening or replacement. It is packaged individually and sold as a single unit.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance in small-bore applications
• TiN coating reduces friction and extends tool life
• Right-hand cutting direction for standard lathe setup
• 0.2-inch minimum bore diameter enables work on very small internal diameters
• 0.25-inch shank diameter fits standard boring bar holders and quick-change tooling systems
• 2.5-inch overall length suits compact turret and gang-tool configurations

Compatibility

Designed for use in boring bar holders and tooling systems that accept a 0.25-inch round shank. Suitable for CNC turning centers and manual lathes configured for right-hand internal boring operations.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's tooling setup procedures. Ensure the machine spindle is fully stopped and the control is in an emergency-stop or locked-out state before seating or removing the bar from its holder. Overhang should be minimized to the shortest length that clears the workpiece to reduce chatter and deflection. Verify holder clamping torque and tool runout with a dial indicator before beginning a cut.
