Accupro ACC-BB110200 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO ACC-BB110200 is a solid carbide boring bar designed for small-diameter internal boring operations on lathes and machining centers. Built from submicron-grade carbide, it delivers the hardness and wear resistance needed for tight-tolerance work in small bores. The bar has a minimum bore diameter of 0.1100 inches, a maximum bore depth of 0.2000 inches (13/64 inches), and a 1/8 inch shank diameter. Overall length is 1.5 inches. The right-hand cutting direction suits standard lathe setups. Machinists and toolroom professionals working on precision components rely on this type of bar when bore diameters fall below the range of conventional tooling.

This boring bar is suited for small-bore finish and semi-finish operations in metals and non-ferrous materials on CNC lathes, manual lathes, and live-tooling setups. It is a practical choice for precision machining of hydraulic fittings, medical components, instrument parts, and other small-diameter bored features where dimensional accuracy and surface finish are critical. The compact overall length of 1.5 inches reduces overhang and helps maintain rigidity at small bore diameters.

Key Features

• Submicron solid carbide construction for superior hardness and edge retention
• Minimum bore diameter of 0.1100 inches for tight small-bore work
• Maximum bore depth of 0.2000 inches (13/64 inches)
• 1/8 inch shank diameter for compatibility with small boring bar holders
• Right-hand cutting direction for standard lathe orientation
• Compact 1.5 inch overall length reduces overhang and improves rigidity

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for standard 1/8 inch boring bar holders used in small-bore lathe and machining center applications.

Installation Notes

Installation is performed by qualified machinists familiar with lathe or machining center tooling setup. Secure the shank firmly in a compatible 1/8 inch boring bar holder and verify tool centerline height before cutting. Power down and lock out the machine spindle before changing or adjusting tooling. Avoid applying side loads beyond the bar's rated bore depth to prevent deflection or tool breakage.
