Accupro ACC-BBL3602500 Boring Bar 3/8 Inch Shank Left Hand

Product Description

The ACCUPRO ACC-BBL3602500 is a left-hand boring bar engineered for precision internal boring operations on CNC lathes and manual turning centers. Constructed from submicron-grade solid carbide, this bar delivers the rigidity and wear resistance required for tight-tolerance bore work. It accepts a minimum bore diameter of 0.3600 inches and reaches a maximum bore depth of 2.5 inches, making it well-suited for shallow-to-moderate depth applications. The 3/8-inch shank diameter and 4-inch overall length provide a compact, stable profile for close-clearance setups. Machinists and tool-and-die professionals use this bar where carbide rigidity is essential for chatter-free finishes.

This boring bar is intended for left-hand cutting applications on lathes configured for reverse-rotation or for specific tool orientation requirements. Its submicron carbide construction supports use in ferrous and non-ferrous materials where surface finish and dimensional accuracy are critical. The compact shank and controlled reach make it appropriate for production turning environments as well as job-shop operations requiring repeatable bore sizing without tool deflection.

Key Features

• Submicron-grade solid carbide construction for high rigidity and extended tool life
• Left-hand cutting direction for reverse-rotation or specialized setup requirements
• Minimum bore diameter of 0.3600 inches suits small-bore precision applications
• Maximum bore depth of 2.5 inches with a 4-inch overall length for stable reach
• 3/8-inch shank diameter for compatibility with standard boring bar holders

Compatibility

Designed as an OEM-style replacement or direct-fit boring bar for standard 3/8-inch boring bar holders used in CNC and manual lathe tooling systems.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the machine spindle is fully stopped and the tooling turret or holder is depressurized before mounting the bar. Secure the shank firmly in the boring bar holder to the holder manufacturer's specified clamping torque using appropriate hex or clamping hardware. Verify bar overhang does not exceed recommended length-to-diameter ratios to minimize deflection during cutting.
