Accupro ACC-BBL230900 Boring Bar Left Hand Solid Carbide

Product Description

The ACCUPRO ACC-BBL230900 is a left-hand cut boring bar manufactured from submicron-grade solid carbide. It is designed for internal boring operations on CNC lathes, manual lathes, and turning centers where precise, small-diameter bores are required. The bar accepts a minimum bore diameter of 0.23 inches and reaches a maximum bore depth of 0.9 inches. With a 5/16-inch shank diameter and an overall length of 2.5 inches, it fits standard boring bar holders used in light to medium turning applications. The bright finish coating reduces friction and aids chip evacuation in tight bore geometries. Machinists and toolroom technicians working with close-tolerance internal features will find this bar suited to that work.

This boring bar is intended for use in precision machining environments including job shops, production turning cells, and toolroom operations. Its submicron carbide construction makes it appropriate for finishing passes and tight-tolerance bore work in ferrous and non-ferrous materials. The left-hand cutting direction accommodates specific workholding setups or back-boring requirements where a standard right-hand bar cannot be used.

Key Features

• Minimum bore diameter of 0.23 inches for small-diameter internal features
• Maximum bore depth of 0.9 inches
• Left-hand cutting direction for back-boring or reversed-spindle setups
• Submicron-grade solid carbide construction for rigidity and wear resistance
• 5/16-inch shank diameter fits standard boring bar holders
• Bright finish coating reduces friction and aids chip flow

Compatibility

Designed as an OEM-style replacement or direct tooling addition for standard boring bar holders accepting a 5/16-inch shank diameter on CNC and manual turning equipment.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Secure the shank firmly in the boring bar holder to the holder manufacturer's specified clamping torque before use. Ensure the machine spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Do not exceed the recommended overhang length for the shank diameter, as excessive overhang increases vibration and reduces bore quality.
