Accupro ACC-BB060300G Boring Bar Solid Carbide Tin

Product Description

The ACCUPRO ACC-BB060300G is a micrograin solid carbide boring bar designed for precision internal boring operations on small-diameter features. It cuts in a right-hand direction with a minimum bore diameter of 0.06 inches and a maximum bore depth of 0.3 inches. The 1/8-inch shank diameter and 1.5-inch overall length make this a compact tool suited for CNC lathes, manual lathes, and turning centers handling tight-tolerance bores. A titanium nitride (TiN) finish coating is applied to extend tool life and reduce friction at the cutting edge. Machinists and toolroom operators working on precision components with small internal diameters will find this bar sized for that specific application.

This boring bar is intended for small-bore finish and semi-finish turning operations in ferrous and non-ferrous materials. The micrograin carbide substrate provides the edge strength and rigidity needed to hold tolerance in shallow, tight-diameter bores. With a 1/8-inch shank, it fits standard boring bar holders and tool blocks designed for that shank size. Typical applications include aerospace components, hydraulic fittings, medical parts, and other precision machined features requiring controlled internal dimensions at very small diameters.

Key Features

• Minimum bore diameter of 0.06 inches for very small internal features
• Maximum bore depth of 0.3 inches
• Right-hand cutting direction
• Micrograin solid carbide construction for edge rigidity and wear resistance
• TiN finish coating reduces friction and extends tool life
• 1/8-inch shank diameter fits standard small-bore tool holders

Compatibility

Designed as a direct-fit replacement for standard 1/8-inch shank boring bar holders used on CNC and manual lathes performing small-diameter internal boring operations.

Installation Notes

Installation is performed by a machinist or toolroom technician. Ensure the machine spindle is fully stopped and the turret or tool post is in a safe position before mounting or removing the boring bar. Secure the 1/8-inch shank firmly in the tool holder to the holder manufacturer's specified clamping method to prevent chatter and deflection. Verify bore depth and diameter setup with an appropriate gauge before running production cuts.
