The ACCUPRO ACC-BB2301400 is a solid carbide boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. Machined from submicron-grade carbide with a bright finish coating, this bar delivers tight tolerances and consistent surface finishes in small-bore applications. It accepts a minimum bore diameter of 0.23 inches and reaches a maximum bore depth of 1.4 inches. The right-hand cutting direction suits standard lathe setups. With a 5/16-inch shank diameter and an overall length of 2.5 inches, it fits standard boring bar holders used in production and job-shop environments. Machinists and toolroom professionals working with small-diameter bores rely on this bar for its rigidity and wear resistance.
This boring bar is suited for light-to-medium internal turning work in ferrous and non-ferrous materials where small bore diameters demand a rigid, compact tooling solution. It is appropriate for production turning cells, toolroom work, and prototype machining where bore diameter precision and repeatability are critical. The submicron carbide grade is particularly effective in applications requiring fine surface finishes or when cutting harder workpiece materials at elevated speeds.
Designed as a direct-fit replacement-style boring bar for standard 5/16-inch boring bar holders used in CNC turning centers and manual lathes requiring right-hand internal boring tooling.
Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before mounting or removing the boring bar. Secure the shank firmly in the boring bar holder to the holder manufacturer's specified clamping torque using appropriate hex keys. Confirm tool overhang is minimized relative to bore depth to reduce chatter and deflection before initiating a cut.
