Accupro ACC-BB100500A Boring Bar Micrograin Solid Carbide

Product Description

The ACCUPRO ACC-BB100500A is a solid carbide boring bar designed for small-diameter internal boring operations on CNC lathes and manual turning centers. Built from micrograin solid carbide, this right-hand cut tool delivers consistent chip formation and extended tool life in demanding materials including hardened steels, cast iron, and high-temperature alloys. A TiAlN finish coating adds thermal resistance and reduces wear at elevated cutting speeds. With a 0.1-inch minimum bore diameter and a 0.5-inch maximum bore depth, it is suited for tight, shallow bore applications where rigidity and precision are critical. Machinists and toolroom professionals install this bar in standard boring bar holders on production and job-shop turning equipment.

This boring bar is intended for small-bore finish and semi-finish turning operations in both production and prototype environments. The 1/8-inch shank diameter fits standard boring bar holders sized for small-diameter tooling. At 1.5 inches overall length, the ACC-BB100500A is compact enough for confined toolpost setups. It is well suited to precision internal turning in medical, aerospace, and general machining applications where bore diameters start at 0.1 inches and depth requirements do not exceed 0.5 inches.

Key Features

• Micrograin solid carbide construction for superior rigidity and edge retention in small bores
• TiAlN finish coating provides heat resistance and extended tool life at higher cutting speeds
• Right-hand cutting direction for standard lathe toolpost orientation
• 0.1-inch minimum bore diameter enables precise machining of very small internal features
• 1/8-inch shank diameter fits compact boring bar holders without additional adapters
• 1.5-inch overall length keeps overhang minimal to reduce chatter in tight setups

Compatibility

Designed for use in boring bar holders accepting a 1/8-inch shank diameter on CNC and manual turning centers performing small-diameter internal boring operations.

Installation Notes

Installation is performed by a machinist or toolroom technician. Power down and lock out the machine before seating or removing the boring bar from its holder. Ensure the shank is fully engaged in the holder to the recommended grip length before clamping to minimize deflection. Follow the machine manufacturer and tooling manufacturer guidelines for feed, speed, and depth-of-cut parameters appropriate to the workpiece material.
