Accupro ACC-BBL3601000 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO ACC-BBL3601000 is a solid carbide boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. Built from submicron-grade carbide with a bright finish coating, this bar delivers consistent dimensional accuracy in tight-tolerance bore work. It features a 3/8 inch shank diameter and a 2.5 inch overall length, with a minimum bore diameter of 0.36 inches and a maximum bore depth of 1 inch. The left-hand cutting direction suits specific tooling setups where conventional right-hand bars cannot be used. Machinists and tool-and-die professionals rely on this type of bar for finish boring passes where rigidity and edge retention are critical.

This boring bar is suited for light to medium internal turning applications in job shops, production machining environments, and maintenance machining settings. Its compact overall length and 3/8 inch shank make it compatible with standard boring bar holders and quick-change tooling systems used on small to mid-size lathes. The bright finish reduces built-up edge on non-ferrous materials and assists with chip flow during through-bore and blind-bore operations.

Key Features

• Submicron solid carbide construction for superior hardness and edge retention
• Left-hand cutting direction for specialized tooling orientations
• Minimum bore diameter of 0.36 inches enables work in small-diameter bores
• Maximum bore depth of 1 inch suitable for standard through and blind bore applications
• Bright finish coating reduces friction and aids chip evacuation
• 3/8 inch shank diameter fits standard boring bar holder sizes

Compatibility

Designed as an OEM-style replacement or direct tooling addition for standard 3/8 inch boring bar holders used on CNC and manual lathes requiring left-hand internal cutting tools.

Installation Notes

Installation is performed by qualified machinists following shop tooling procedures. Secure the shank firmly in the boring bar holder to the specified clamping torque for your tooling system before operation. Ensure the machine spindle is fully stopped and the lathe is powered down before mounting or removing the bar. Inspect the cutting edge for chips or wear before each use, as carbide tools can fracture if run with damaged edges.
