Accupro B110200A Boring Bar 0.11 in Min Bore Carbide

Product Description

The ACCUPRO B110200A is a solid carbide boring bar designed for precision internal boring operations on CNC and manual lathes. Built from submicron-grade carbide with an AlTiN finish coating, this tool delivers consistent performance in hardened and abrasive materials where standard carbide grades wear prematurely. It cuts in a right-hand direction with a minimum bore diameter of 0.11 inches and a maximum bore depth of 0.2000 inches (13/64 inches). The 1/8-inch shank diameter and 1.5-inch overall length make it suited to small-bore work requiring tight access and dimensional accuracy.

This boring bar is used in precision machining environments for small-diameter internal boring on ferrous and non-ferrous workpieces. It fits toolholders accepting a 1/8-inch shank and is appropriate for production and job-shop settings where close-tolerance bores are required. Machinists and CNC operators working on instrument components, hydraulic fittings, and similar small-part applications will find this geometry and coating combination well matched to finishing and semi-finishing passes.

Key Features

• Submicron-grade solid carbide construction for wear resistance in abrasive and hardened materials
• AlTiN coating improves thermal resistance and tool life at higher cutting speeds
• Right-hand cut geometry for standard lathe and boring applications
• 0.11-inch minimum bore diameter allows access to very small internal diameters
• Maximum bore depth of 0.2000 inches (13/64 inches) suitable for shallow precision bores
• Compact 1/8-inch shank and 1.5-inch OAL for use in tight toolholding setups

Compatibility

Designed for use in toolholders and boring heads accepting a 1/8-inch round shank; verify minimum bore diameter and bore depth requirements against the specific toolholder and workpiece before use.

Installation Notes

Installation should be performed by a qualified machinist following standard toolroom practices. Ensure the boring bar is clamped securely with adequate shank engagement in the toolholder to minimize overhang and chatter. Power down and lock out the machine spindle before inserting or adjusting the tool. Do not exceed the maximum bore depth specification, as doing so can cause deflection or tool breakage.
