Accupro ACC-BBL3601150 Boring Bar Left Hand Solid Carbide

Product Description

The ACCUPRO ACC-BBL3601150 is a solid carbide boring bar designed for precision internal boring operations on CNC and manual turning equipment. Built from submicron-grade solid carbide with a bright finish, it delivers consistent dimensional accuracy in tight-tolerance bore applications. The left-hand cutting direction suits specific spindle orientations and tooling configurations where right-hand tools cannot be applied. With a 0.36-inch minimum bore diameter and a 3/8-inch shank diameter, this bar fits standard boring bar holders commonly found in production and job shop environments. Machinists and tooling specialists use this bar where rigidity and wear resistance are critical to achieving finish bore specifications.

This boring bar is suited for ferrous and non-ferrous materials in both production and prototype machining environments. Its 1.15-inch maximum bore depth and 2.5-inch overall length make it appropriate for shallow-to-moderate bore depths in parts such as bushings, housings, and hydraulic components. It is intended for use in machine shops where precise bore sizing is required and cutting tool geometry must match the programmed cutting direction.

Key Features

• Submicron solid carbide construction for high wear resistance and dimensional stability
• Left-hand cutting direction for specific spindle and tooling setups
• 0.36-inch minimum bore diameter for tight internal bore applications
• 1.15-inch maximum bore depth supports shallow-to-moderate bore operations
• 3/8-inch shank diameter fits standard boring bar holder collets and blocks
• Bright finish coating reduces friction and aids chip evacuation

Compatibility

Designed as an OEM-style replacement or direct tooling addition for standard boring bar holders accepting a 3/8-inch shank diameter in CNC lathe and manual turning applications.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before mounting or removing the boring bar. Secure the shank fully within the boring bar holder to the depth recommended by the holder manufacturer to prevent deflection during cutting. Verify cutting direction matches spindle rotation and programmed tool path before initiating a cut.
