Accupro ACC-BB110500A Boring Bar Micrograin Solid Carbide

Product Description

The ACCUPRO ACC-BB110500A is a solid carbide boring bar designed for precision internal boring operations on small-diameter bores. Built from micrograin solid carbide and coated with TiAlN, it handles tight tolerances in hardened and abrasive workpiece materials. The right-hand cutting direction suits standard CNC and manual lathe setups. With a minimum bore diameter of 0.11 inches and a maximum bore depth of 0.50 inches, this bar is sized for detailed, close-tolerance work in small bore applications. The 1/8-inch shank diameter and 1.50-inch overall length make it compatible with compact toolholding setups. Machinists and toolroom operators working in production or jobshop environments are the primary users.

This boring bar is suited for light-duty internal boring on CNC lathes, manual lathes, and small machining centers. It is particularly well-matched to applications requiring fine bore finishes in ferrous and non-ferrous materials where a small shank and short overall length are necessary. The TiAlN coating improves wear resistance and allows higher cutting speeds compared to uncoated carbide, making it a practical choice for production runs and prototype work alike.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance in demanding cuts
• TiAlN finish coating extends tool life and supports higher cutting speeds
• Minimum bore diameter of 0.11 inches enables work on very small internal features
• Maximum bore depth of 0.50 inches suits shallow internal profiles
• Right-hand cutting direction for standard lathe and boring setups
• 1/8-inch shank diameter fits compact toolholders and small-bore bar holders

Compatibility

Designed as an OEM-style solid carbide boring bar for use in standard 1/8-inch bore bar holders on CNC lathes, manual lathes, and small machining centers requiring right-hand internal boring capability.

Installation Notes

Installation is performed by qualified machinists. Power down and lock out the spindle before mounting or adjusting the boring bar in the toolholder. Ensure the shank is properly seated and clamped to the full recommended engagement length to minimize deflection at small bore depths. Follow shop-standard toolholder torque procedures and verify bore dimensions with appropriate gauging before committing to a full production run.
