Accupro ACC-BB180600 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO ACC-BB180600 is a solid carbide boring bar designed for precision internal boring operations on lathes and machining centers. Built from submicron-grade carbide with a bright finish coating, it delivers the rigidity and edge retention needed for tight-tolerance bores. The bar accepts a minimum bore diameter of 0.18 inches and reaches a maximum bore depth of 0.60 inches. With a 0.25-inch shank diameter and a 2.5-inch overall length, this is a compact tool suited for small-bore work where dimensional accuracy is critical. Machinists and tool-and-die professionals are the primary users.

This boring bar is intended for small-bore internal turning applications in metalworking environments, including production machining and job shop work. Its right-hand cutting direction suits standard spindle rotation setups. The submicron carbide grade offers improved wear resistance compared to standard carbide grades, making it a practical choice for harder workpiece materials or high-cycle runs. It ships in single-unit packaging with a minimum order quantity of one.

Key Features

• Submicron solid carbide construction for superior wear resistance and edge stability
• Minimum bore diameter of 0.18 inches for tight small-bore applications
• Maximum bore depth of 0.60 inches
• Right-hand cutting direction for standard spindle rotation
• Bright finish coating on the shank and body
• 0.25-inch shank diameter with 2.5-inch overall length for compact toolholder fitment

Compatibility

Designed as an OEM-style replacement or direct-use boring bar compatible with toolholders accepting a 0.25-inch round shank, as typically found on CNC lathes, manual lathes, and small machining centers configured for internal boring operations.

Installation Notes

Installation should be performed by a qualified machinist following standard machine shop safety procedures. Ensure the machine spindle is fully stopped and the machine is locked out before mounting or removing the boring bar. Secure the shank firmly in the toolholder to the recommended clamping depth to minimize overhang and chatter. Verify bore diameter and depth clearances before engaging the cut.
