Accupro ACC-BBL120500 Boring Bar Left Hand Solid Carbide

Product Description

The ACCUPRO ACC-BBL120500 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, it delivers consistent cutting performance in tight-tolerance bore applications. The left-hand cutting direction suits specific spindle orientations and tooling setups where standard right-hand bars are not appropriate. With a 0.12 inch minimum bore diameter and a 3/16 inch shank, this bar handles small-diameter work where rigidity and material hardness are critical. It weighs 0.0625 pounds and measures 2 inches in overall length.

This boring bar is suited for machining shops, tool rooms, and production environments that require accurate small-bore finishing and sizing. The submicron carbide grade performs well in ferrous and non-ferrous materials where surface finish and dimensional accuracy are priorities. The bright coating keeps the bar free of additional coating thickness that could affect close-tolerance fits. Machinists and CNC setup techs working on small-diameter bores will find this bar appropriate for both finishing passes and light roughing in confined bore depths up to 0.5 inches.

Key Features

• Submicron solid carbide construction for rigidity and wear resistance in small-bore applications
• Left-hand cutting direction for specific spindle and toolpath requirements
• 0.12 inch minimum bore diameter for tight internal geometry work
• Maximum bore depth of 0.5 inches suits shallow internal features
• Bright finish with no coating buildup for close-tolerance applications
• Compact 2 inch overall length for use in confined tooling setups

Compatibility

Designed as an OEM-style replacement or direct-fit boring bar for CNC lathes and manual turning centers that accept a 3/16 inch shank boring bar with left-hand cutting orientation.

Installation Notes

Installation of boring bars should be performed by a qualified machinist or CNC setup technician. Power down and lock out the machine spindle before mounting or removing tooling. Ensure the shank is clamped securely in the tool holder to the full recommended engagement depth to minimize overhang and chatter. Verify cutting direction and spindle rotation before initiating any cutting operation.
