Accupro ACC-BB180900G Boring Bar Solid Carbide Tin

Product Description

The ACCUPRO ACC-BB180900G is a micrograin solid carbide boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. It accepts a minimum bore diameter of 0.18 inches and reaches a maximum bore depth of 0.9 inches, making it well suited for small-diameter, close-tolerance work. The 1/4-inch shank diameter and 2.5-inch overall length keep the tool compact and rigid. A titanium nitride (TiN) finish coating reduces friction and extends cutting edge life. Right-hand cut orientation is standard. Machinists and toolroom operators working with tight bore tolerances will find this bar appropriate for both production and prototype applications.

This boring bar is intended for use in small-bore finishing and semi-finishing operations where dimensional accuracy is critical. Typical applications include bearing bores, bushing seats, and precision holes in ferrous and non-ferrous workpieces. The micrograin carbide substrate provides the hardness and wear resistance needed for interrupted cuts and abrasive materials. It is sized for use in toolholders and turrets that accept a 1/4-inch round shank.

Key Features

• Micrograin solid carbide construction for high rigidity and wear resistance
• TiN finish coating reduces tool wear and extends service life
• 0.18-inch minimum bore diameter for small-hole applications
• 0.9-inch maximum bore depth supports shallow-to-moderate reach requirements
• Right-hand cut configuration for standard lathe and turning center setups
• 1/4-inch shank diameter fits a wide range of standard toolholders

Compatibility

Designed as a replacement or spare boring bar for toolholders and turrets accepting a 1/4-inch round shank, suitable for CNC lathes and manual turning equipment configured for right-hand cutting tools.

Installation Notes

Installation should be performed by a qualified machinist with the machine powered down and all motion axes locked. Secure the shank firmly in the toolholder to the full recommended engagement depth to minimize overhang and chatter. Confirm tool centerline height before initiating a cut. Inspect the cutting edge and TiN coating for chips or wear before each use.
