Accupro ACC-BBL3601800 Boring Bar Left Hand Solid Carbide

Product Description

The ACCUPRO ACC-BBL3601800 is a solid carbide boring bar designed for internal diameter boring operations on CNC lathes and manual turning centers. Built from submicron-grade solid carbide with a bright finish, it provides rigidity and wear resistance in tight-bore applications. The bar cuts in the left-hand direction, with a minimum bore diameter of 0.36 inches and a maximum bore depth of 1.8 inches. The 3/8-inch shank diameter and 3-inch overall length make it suitable for close-clearance setups where reach and rigidity both matter. Machinists and toolroom technicians working in ferrous and non-ferrous materials will find this bar appropriate for fine-finish and sizing passes.

This boring bar is suited to shop environments running tight-tolerance work on small-bore components. Its submicron carbide grade supports use in hardened materials and applications where surface finish and dimensional accuracy are critical. The left-hand cutting geometry is appropriate for back-boring operations or setups where workpiece orientation or spindle configuration requires a reverse-cut tool. It is sold individually and is a practical stocking item for job shops, production machining cells, and toolroom applications.

Key Features

• Submicron solid carbide construction for improved wear resistance and edge retention
• Left-hand cutting direction suits back-boring and reverse-spindle applications
• Minimum bore diameter of 0.36 inches for small-bore internal work
• Maximum bore depth of 1.8 inches provides reach for deeper bore features
• Bright finish coating on the shank and body
• 3/8-inch shank diameter fits standard boring bar holders and quick-change tooling systems

Compatibility

Designed for use in standard 3/8-inch boring bar holders on CNC and manual turning centers capable of accepting solid carbide boring bars in this shank size range.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the shank firmly in the boring bar holder and verify overhang does not exceed recommended length-to-diameter ratios for the material being cut. Power down and lock out the machine spindle before inserting or removing tooling. Inspect the cutting edge for chipping before each use, as carbide tooling can suffer microchipping that is not always visible without magnification.
