Accupro ACC-BBL110600 Boring Bar Left Hand Solid Carbide

Product Description

The ACCUPRO ACC-BBL110600 is a left-hand cut boring bar machined from submicron-grade solid carbide. It is designed for precision internal boring operations on CNC lathes, manual lathes, and boring machines where tight tolerances and surface finish quality are required. The bar features a 0.11 inch minimum bore diameter and a maximum bore depth of 0.6 inches, making it suited for small-diameter, shallow-bore applications. The bright finish coating reduces built-up edge and supports chip flow in confined bore geometries. Machinists and toolroom operators working on small components rely on this grade of carbide for consistent performance at elevated cutting speeds.

This boring bar is appropriate for use in production and job-shop environments where small-bore internal turning is performed on ferrous and non-ferrous workpieces. Its 1/8 inch shank diameter fits standard boring bar holders and quick-change tooling systems designed for that shank size. The left-hand cutting direction suits specific machine orientations and back-boring setups where a right-hand bar cannot be used. It is a single-piece solid carbide construction, meaning there are no inserts to index or replace.

Key Features

• Submicron-grade solid carbide construction for rigidity and wear resistance in small-bore applications
• Left-hand cutting direction for back-boring and reverse-orientation setups
• 0.11 inch minimum bore diameter suits tight, small-diameter internal features
• 0.6 inch maximum bore depth provides adequate reach for shallow internal profiles
• Bright finish coating helps reduce friction and built-up edge at the cutting zone
• 1/8 inch shank diameter fits standard small-bore toolholders

Compatibility

Designed for use in boring bar holders and tooling systems that accept a 1/8 inch shank diameter. Verify holder bore size and clamping clearance before installation.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before mounting or removing the boring bar. Secure the shank firmly in the holder to the full recommended engagement depth to minimize deflection and chatter in small-diameter bores. Do not exceed the maximum bore depth of 0.6 inches, as overreach increases the risk of tool deflection and workpiece damage.
