Accupro ACC-BB160600G Boring Bar Micrograin Solid Carbide

Product Description

The ACCUPRO ACC-BB160600G is a micrograin solid carbide boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. It cuts right-hand with a minimum bore diameter of 0.16 inches and a maximum bore depth of 0.6 inches. The 3/16-inch shank diameter and 2-inch overall length make it well suited for small-bore finish and semi-finish work where rigidity and dimensional accuracy are critical. A titanium nitride (TiN) coating reduces friction and extends tool life in ferrous and non-ferrous applications. Machinists and toolroom technicians working on tight-tolerance bores will find this bar delivers consistent cutting performance in both production and prototype environments.

This boring bar is intended for small-diameter internal machining operations typical of job shops, production machining cells, and toolroom environments. It handles applications where a standard insert boring bar cannot reach minimum bore sizes at or near 0.16 inches. The compact geometry makes it a practical choice for short-depth blind bore and through-bore operations in steel, aluminum, cast iron, and similar machinable materials.

Key Features

• Micrograin solid carbide construction for high rigidity and sharp edge retention in small-bore applications
• TiN coating reduces cutting friction and improves wear resistance
• Minimum bore diameter of 0.16 inches enables machining of very small internal diameters
• Maximum bore depth of 0.6 inches suits short blind and through-bore operations
• Right-hand cutting direction compatible with standard lathe spindle rotation
• 3/16-inch shank diameter fits common small-bore toolholders and quick-change systems

Compatibility

Designed as an OEM-style replacement and standard toolroom boring bar for use in any lathe or turning center toolholder accepting a 3/16-inch round shank.

Installation Notes

This bar is installed by a machinist or toolroom technician into a compatible boring bar holder or quick-change toolpost. Power down and lock out the machine spindle before seating or adjusting the bar in the holder. Ensure the shank is fully seated and clamped to the holder manufacturer's specified engagement length to minimize overhang-induced vibration. Do not exceed the maximum bore depth of 0.6 inches, as extended overhang beyond the designed depth can cause chatter and tool deflection.
