Accupro ACC-BB080400A Boring Bar Micrograin Solid Carbide

Product Description

The ACCUPRO ACC-BB080400A is a solid carbide boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. Built from micrograin solid carbide with a TiAlN finish coating, it delivers the wear resistance and edge retention needed for tight-tolerance bore work. The bar features a right-hand cutting direction, a minimum bore diameter of 0.08 inches, and a maximum bore depth of 0.4 inches. With a 0.125-inch shank diameter and an overall length of 1.5 inches, this is a compact tool suited for small-diameter bore applications where rigidity and precision matter. It is typically installed by machinists and toolroom technicians in production and job-shop environments.

This boring bar is well suited for small-bore finish and semi-finish turning operations in materials where micrograin carbide excels, including hardened steels, stainless steels, cast iron, and high-temperature alloys. The TiAlN coating extends tool life at elevated cutting temperatures, making it a practical choice for dry or minimal-coolant machining strategies. The compact overall length and small shank diameter make it appropriate for micro-boring applications on Swiss-type, gang-tool, or turret-style lathes where access is limited.

Key Features

• Micrograin solid carbide construction for improved wear resistance and edge sharpness
• TiAlN finish coating enhances performance in high-temperature cutting conditions
• Right-hand cutting direction for standard lathe toolpost setups
• 0.08-inch minimum bore diameter enables very small internal bore work
• 0.125-inch shank diameter fits compact toolholders on small-format lathes
• 1.5-inch overall length provides rigidity in tight-clearance boring situations

Compatibility

Designed as an OEM-style solid carbide boring bar for use in toolholders accepting a 0.125-inch round shank, common on small CNC and manual turning centers.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before mounting or removing the boring bar. Secure the shank firmly in a compatible toolholder to the full recommended engagement depth to minimize deflection and chatter. Inspect the cutting edge for chips or wear before each use, as carbide tools can fail without visible warning if edges are compromised.
