Accupro ACC-BB1801100G Boring Bar 0.18 in Carbide Tin

Product Description

The ACCUPRO ACC-BB1801100G is a solid carbide boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. Built from micrograin carbide with a titanium nitride (TiN) finish coating, this bar delivers consistent cutting performance and extended tool life in tight-tolerance bore applications. It features a right-hand cutting direction, a 0.25-inch shank diameter, and a 2.5-inch overall length, making it well suited for small-diameter bore work where rigidity and precision are critical. Machinists and tool-and-die professionals rely on this class of boring bar for finish boring operations requiring close dimensional control.

This boring bar is intended for small-bore internal turning applications with a minimum bore diameter of 0.18 inches. Its compact geometry fits into restricted bore entries where larger tooling cannot be used. The TiN coating reduces friction and improves wear resistance, making it appropriate for ferrous and non-ferrous materials across production and job-shop environments. The 0.25-inch shank provides compatibility with standard boring bar holders used on most small to mid-size turning centers.

Key Features

• Micrograin solid carbide construction for high rigidity and wear resistance
• TiN finish coating reduces cutting friction and extends tool life
• Right-hand cutting direction for standard lathe operation
• 0.18-inch minimum bore diameter for tight, small-diameter bore applications
• 0.25-inch shank diameter fits standard boring bar tool holders
• 2.5-inch overall length provides reach with minimal overhang in typical setups

Compatibility

Designed for use with standard 0.25-inch boring bar holders on CNC and manual turning centers capable of small-diameter internal boring operations.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Secure the shank firmly in the boring bar holder to the manufacturer-specified clamping torque for the holder being used, ensuring minimal overhang to reduce chatter. Power down and lock out the machine before changing tooling. Verify bore diameter and tool clearance before beginning the cut.
