Accupro ACC-BB110150G Boring Bar Micrograin Solid Carbide

Product Description

The ACCUPRO ACC-BB110150G is a micrograin solid carbide boring bar designed for tight-tolerance internal boring operations on CNC lathes and manual turning centers. It cuts in a right-hand direction and accepts a 0.125-inch shank diameter, making it suited for small-bore work. The bar carries a TiN (titanium nitride) finish coating that extends cutting edge life and reduces friction during the cut. With a minimum bore diameter of 0.11 inches and a maximum bore depth of 0.15 inches, this tool is purpose-built for precision small-diameter applications where rigidity and edge retention are critical. Machinists and toolroom technicians working in production or job-shop environments will find this bar a reliable option for fine finishing passes.

This boring bar is intended for small-bore internal turning on metals and similar materials where minimal bore diameter and shallow depth requirements apply. Its micrograin carbide construction handles hardened and abrasive workpiece materials that would quickly degrade lower-grade tooling. The 1.5-inch overall length keeps the tool compact and maximizes rigidity in confined setups. Shops running small-diameter bores in production turning, die work, or precision repair applications are the primary users of this tool.

Key Features

• Micrograin solid carbide construction for superior edge retention and rigidity in small-bore operations
• TiN finish coating reduces cutting friction and extends tool life
• Right-hand cutting direction for standard lathe setups
• 0.11-inch minimum bore diameter enables work in very small internal diameters
• 0.125-inch shank diameter fits standard small-bore toolholders
• 1.5-inch overall length provides a compact, rigid profile

Compatibility

Designed as an OEM-style replacement or direct tooling addition for standard small-bore turning setups that accept a 0.125-inch shank boring bar with right-hand cutting direction.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the 0.125-inch shank firmly in a compatible boring bar holder or toolpost before operation; confirm the tool is on centerline with the workpiece spindle axis. Power down and lock out the machine before changing or adjusting tooling. Do not exceed the 0.15-inch maximum bore depth to avoid deflection or tool breakage.
