Accupro ACC-BBL110150 Boring Bar Left Hand Solid Carbide

Product Description

The ACCUPRO ACC-BBL110150 is a solid carbide boring bar designed for tight-tolerance internal boring operations on small-diameter workpieces. Built from submicron carbide grade material with a bright finish, it delivers the rigidity and edge retention needed for precision cuts in hardened and abrasive materials. The left-hand cutting direction makes it suited for specific spindle orientations and reverse-boring setups. With a minimum bore diameter of 0.11 inches and a maximum bore depth of 0.15 inches, this bar is intended for micro-bore applications where standard tooling cannot reach. Machinists and toolroom technicians working on CNC lathes and boring mills will find this bar well-matched to their needs.

This boring bar is used in precision machining environments including job shops, toolrooms, and production facilities running CNC or manual lathes. It is particularly suited for small-diameter internal features in components such as bushings, valve bodies, and instrument parts. The 1/8-inch shank diameter allows it to fit standard small-bore toolholders and quick-change systems. Left-hand cut geometry supports climb-boring operations or machines configured for reverse rotation. The 1-1/2-inch overall length keeps the tool compact and minimizes overhang-related deflection.

Key Features

• Submicron solid carbide construction for high rigidity and wear resistance
• Left-hand cutting direction for reverse-rotation or specific toolholder setups
• Minimum bore diameter of 0.11 inches for micro-bore applications
• Maximum bore depth of 0.15 inches
• Bright finish coating with no added coating thickness to affect dimensional tolerances
• Compact 1-1/2-inch overall length minimizes tool deflection

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for standard 1/8-inch shank boring bar holders used in small-diameter internal boring applications on CNC and manual lathes.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the shank firmly in a compatible 1/8-inch toolholder and verify proper tool stick-out before beginning any cut. Power down and lock out the machine spindle before inserting or removing the bar. Avoid excessive overhang beyond the rated bore depth to prevent deflection and tool breakage.
