Accupro ACC-BBL4902600 Boring Bar Left Hand Solid Carbide

Product Description

The ACCUPRO ACC-BBL4902600 is a solid carbide boring bar designed for internal diameter boring operations on metal workpieces. Built from submicron-grade carbide with a bright finish coating, it delivers consistent cutting performance in tight-tolerance applications. The bar accepts a minimum bore diameter of 0.49 inches and reaches a maximum bore depth of 2.6 inches, making it well-suited for through and blind-hole boring on lathes and machining centers. The 0.5-inch shank diameter and 4-inch overall length provide rigid tool holding in standard boring bar holders. Left-hand cutting direction is the defining orientation of this tool.

This boring bar is used in precision machining environments including job shops, production machining cells, and toolrooms. It is appropriate for both CNC turning centers and manual lathes where left-hand cut geometry is required. The submicron carbide grade performs reliably in ferrous and non-ferrous materials at moderate-to-high cutting speeds. Machinists and tool-and-die professionals specify this style of bar for fine boring passes where surface finish and dimensional accuracy are priorities.

Key Features

• Submicron solid carbide construction for extended tool life and rigidity
• Left-hand cutting direction for specific bore orientation requirements
• Minimum bore diameter of 0.49 inches enables work in small-diameter bores
• Maximum bore depth of 2.6 inches suits a wide range of through and blind-hole applications
• Bright finish coating reduces built-up edge in non-ferrous materials
• 0.5-inch shank diameter fits standard boring bar holders and turrets

Compatibility

Designed as an OEM-style replacement and standard tooling option for boring bar holders accepting a 0.5-inch shank diameter on CNC turning centers and manual lathes.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Secure the shank fully within the tool holder to the manufacturer-recommended clamping depth before operation. Confirm that the machine spindle is at a complete stop and the machine is in an e-stop or locked-out state before loading or unloading the bar. Inspect the cutting edge for chips or wear before each use, as carbide tools are brittle and should not be used if the edge is damaged.
