Accupro B3201100R Boring Bar 0.32 in Solid Carbide Right Hand

Product Description

The ACCUPRO B3201100R is a right-hand solid carbide boring bar engineered for precision internal diameter machining. Built from submicron-grade carbide, it delivers the rigidity and wear resistance required for tight-tolerance bore work in ferrous and non-ferrous materials. With a minimum bore diameter of 0.3200 inches and a maximum bore depth of 1.1000 inches, this bar is suited for small-diameter, moderate-depth applications on CNC lathes and boring mills. The 3/8-inch shank diameter provides secure tool-holder engagement, and the 2.5-inch overall length keeps overhang manageable for chatter-free cuts.

This boring bar is intended for machinists and tool-and-die professionals working on precision lathe or mill-turn operations. It fits standard 3/8-inch bore bar holders and is appropriate for production machining, repair work, and custom fabrication where consistent bore finish and dimensional accuracy are required. Typical applications include finishing bores in hydraulic components, pump housings, and close-tolerance mechanical assemblies.

Key Features

• Submicron solid carbide construction for high rigidity and extended tool life
• Right-hand cutting direction for conventional lathe and boring mill setups
• Minimum bore diameter of 0.3200 inches enables small-bore internal work
• Maximum bore depth of 1.1000 inches supports moderate-depth finishing passes
• 3/8-inch shank diameter fits widely available standard boring bar holders
• 2.5-inch overall length minimizes overhang and supports stable, chatter-resistant cuts

Compatibility

Designed for use in standard 3/8-inch shank boring bar holders on CNC and manual lathes or boring mills. No specific machine model compatibility was provided by the manufacturer.

Installation Notes

Installation should be performed by a qualified machinist following the tool-holder manufacturer's torque and clamping specifications. Ensure the machine spindle is fully stopped and the machine is in a safe, locked-out state before mounting or removing the boring bar. Set tool overhang to the minimum length required for the application to maximize rigidity and minimize vibration. Verify shank seating and alignment in the holder before taking any cuts.
