Accupro ACC-BBL110300 Boring Bar Left Hand Solid Carbide

Product Description

The ACCUPRO ACC-BBL110300 is a left-hand cut boring bar machined from submicron-grade solid carbide. It is designed for tight-tolerance internal boring operations on CNC lathes, Swiss-type machines, and small-bore turning centers. The bar handles a minimum bore diameter of 0.11 inches and a maximum bore depth of 0.3 inches, making it well suited for precision finish boring in small cavities. The 1/8-inch shank diameter and 1-1/2-inch overall length (OAL) keep the tool compact for close-clearance work. A bright finish coating is applied to the cutting geometry. Machinists and toolroom technicians working on precision turned components are the primary users of this tool.

This boring bar is applicable to small-bore internal turning operations in job shops, production machining cells, and toolroom environments. The left-hand cutting direction suits specific spindle rotation orientations or backboring setups. Its submicron carbide grade provides the hardness and edge retention needed for ferrous and non-ferrous materials at tight tolerances. The compact overall length allows use in confined toolholding setups where clearance is limited.

Key Features

• Submicron-grade solid carbide construction for hardness and edge retention
• Left-hand cutting direction for reverse-rotation or backboring applications
• Minimum bore diameter of 0.11 inches for small-cavity internal work
• Maximum bore depth of 0.3 inches
• 1/8-inch shank diameter for compatibility with small-bore toolholders
• Bright finish coating on cutting geometry

Compatibility

Designed as an OEM-style replacement or direct-use boring bar for toolholders accepting a 1/8-inch shank diameter in small-bore CNC turning and Swiss-type machine applications.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the shank fully within the toolholder to the recommended grip depth before operation, and verify that the cutting direction matches spindle rotation before engaging the workpiece. Ensure the machine is in a safe, locked-out state when changing or adjusting tooling. Follow the machine manufacturer and shop safety guidelines for boring bar runout and overhang limits.
