Accupro B2301400R Corner Radius Boring Bar Solid Carbide

Product Description

The ACCUPRO B2301400R is a corner radius boring bar designed for precision internal boring operations on CNC and manual lathes. Machined from submicron-grade solid carbide, it delivers the rigidity and wear resistance required for tight-tolerance bore finishing. The bar bores to a minimum diameter of 0.23 inches and reaches a maximum bore depth of 1.4 inches. A bright finish coating reduces built-up edge and friction during cutting. With a 5/16-inch shank diameter and an overall length of 2.5 inches, this bar fits standard boring bar holders found in most turning centers. Right-hand cut geometry suits conventional lathe setups where the tool feeds left toward the chuck.

This boring bar is suited for small-bore finish work in ferrous and non-ferrous materials where a controlled corner radius is required to meet print callouts. The corner radius range of 0.005 to 0.008 inches allows the machinist to select the correct insert profile for the application. Typical use cases include finishing bores on precision housings, bushings, and bearing seats in both job-shop and production environments. A licensed machinist or CNC operator handles installation and setup. This bar is sold individually with a minimum order quantity of one piece.

Key Features

• Submicron solid carbide construction for high rigidity and extended tool life
• Minimum bore diameter of 0.23 inches for small-bore applications
• Maximum bore depth of 1.4 inches
• Corner radius range of 0.005 to 0.008 inches for controlled edge geometry
• Right-hand cut direction for standard lathe orientation
• Bright finish coating reduces friction and built-up edge

Compatibility

Designed as an OEM-style solid carbide boring bar for use in standard 5/16-inch boring bar holders on CNC turning centers and manual lathes requiring right-hand cut internal boring capability.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Power down and lock out the machine before inserting or adjusting the boring bar in its holder. Ensure the shank is fully seated and clamped to the holder manufacturer's specified torque using a calibrated torque wrench. Confirm bore depth and corner radius requirements against the print before commencing the cut.
