Accupro ACC-BB110500G Boring Bar Micrograin Solid Carbide

Product Description

The ACCUPRO ACC-BB110500G is a micrograin solid carbide boring bar designed for precision internal boring operations on small-diameter features. With a minimum bore diameter of 0.11 inches and a maximum bore depth of 0.5 inches, this bar handles tight tolerances in confined bores. The 1/8-inch shank diameter and 1.5-inch overall length make it well suited for use in CNC lathes, machining centers, and manual turning equipment. A titanium nitride (TiN) finish coating improves surface hardness and wear resistance, extending tool life in production environments. Right-hand cut geometry is the standard orientation for most lathe and boring head setups.

This boring bar is intended for machinists and toolroom professionals performing small-bore finishing and semi-finishing operations. It fits standard 1/8-inch boring bar holders and is appropriate for use on ferrous and non-ferrous workpiece materials. Typical applications include small hydraulic fittings, precision bushings, and instrument-component bores where dimensional accuracy is critical. The micrograin carbide substrate provides rigidity and edge retention in short, demanding cuts where chatter control matters.

Key Features

• Micrograin solid carbide construction for rigidity and edge retention in small-bore work
• TiN finish coating increases surface hardness and reduces wear in production use
• 0.11-inch minimum bore diameter accommodates tight, small-diameter features
• 0.5-inch maximum bore depth suitable for through and blind bore applications
• Right-hand cut geometry compatible with standard lathe and boring head setups
• Compact 1/8-inch shank and 1.5-inch OAL for use in tight tool-holding setups

Compatibility

Designed as an OEM-style replacement and standard tooling option for 1/8-inch boring bar holders used in CNC and manual turning applications requiring small-diameter internal boring capability.

Installation Notes

Installation is performed by qualified machinists following standard toolroom practices. Secure the shank firmly in a compatible 1/8-inch boring bar holder and verify tool overhang is minimized to reduce deflection. Power down or e-stop the machine and confirm spindle is at rest before changing tooling. Follow shop-specific speeds and feeds for the carbide grade and workpiece material being machined.
