The ACCUPRO ACC-BB320750 is a solid carbide boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. Built from submicron-grade solid carbide with a bright finish, this bar offers the rigidity and wear resistance needed for tight-tolerance bores. It accepts a minimum bore diameter of 0.32 inches and reaches a maximum bore depth of 0.75 inches. The 3/8-inch shank diameter and 2.5-inch overall length make it well suited for close-quarter internal turning work where a compact, rigid tool is required. Installation and use are handled by machinists and CNC operators in production and job-shop environments.
This boring bar is intended for internal diameter turning in metals and similar materials where a right-hand cutting direction is required. The submicron carbide substrate provides elevated hardness and edge retention, making it appropriate for finishing passes and semi-finish boring where dimensional accuracy and surface finish quality are priorities. The bright (uncoated) finish is well matched to non-ferrous materials and certain ferrous applications where coating interaction is a concern. It ships individually and is sold in single-unit quantities.
Designed as a direct-fit boring bar for tool holders accepting a 3/8-inch round shank, commonly used on CNC lathes and manual turning centers configured for right-hand internal boring operations.
Installation is performed by a machinist or CNC setup technician. Power down and lock out the machine before seating or removing the boring bar from the tool holder. Ensure the shank is fully and evenly clamped in the holder to minimize overhang-related vibration. Verify bore diameter clearance and depth stop settings before initiating a cutting pass.
