Accupro ACC-BB320500G Boring Bar 0.32 in Solid Carbide

Product Description

The ACCUPRO ACC-BB320500G is a solid carbide boring bar designed for precision internal boring operations on CNC and manual lathes. Built from micrograin solid carbide with a titanium nitride (TiN) finish coating, it delivers consistent cutting performance and extended tool life in ferrous and non-ferrous materials. The right-hand cut geometry suits standard lathe setups. With a minimum bore diameter of 0.32 inches and a maximum bore depth of 0.5 inches, this bar is sized for tight-tolerance work in small-diameter bores. The 3/8-inch shank diameter and 2.5-inch overall length keep it compact and rigid in tool holders.

This boring bar is suited for job shops, production machining environments, and tool rooms where small-bore internal turning is required. It is a fit for CNC turning centers and manual lathes running right-hand tooling setups. Machinists and CNC operators working on close-tolerance internal diameters will find the micrograin carbide grade appropriate for finishing and semi-finishing passes in both interrupted and continuous cuts.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• TiN finish coating to reduce friction and extend cutting edge life
• Right-hand cut geometry for standard lathe and turning center setups
• 0.32-inch minimum bore diameter for small-diameter internal turning
• 0.5-inch maximum bore depth suits shallow internal features
• 3/8-inch shank diameter for compatibility with standard tool holders

Compatibility

Designed as an OEM-style solid carbide boring bar for use in standard 3/8-inch tool holders on CNC turning centers and manual lathes requiring right-hand internal boring tooling.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine before mounting or removing tooling. Secure the shank firmly in the tool holder to the holder manufacturer's specified clamping procedure to prevent chatter and deflection. Inspect the cutting edge for chips or wear before each use.
