Accupro ACC-BBL2001300 Boring Bar Left Hand Solid Carbide

Product Description

The ACCUPRO ACC-BBL2001300 is a left-hand cut solid carbide boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. Manufactured from submicron-grade solid carbide with a bright finish, this bar delivers the rigidity and wear resistance required for tight-tolerance bore work. It accepts a 0.25 inch shank diameter and achieves a minimum bore diameter of 0.2 inches with a maximum bore depth of 1.3 inches. Overall length is 2.5 inches. Machinists and tool-and-die professionals use this bar when holding close dimensional tolerances on small-diameter internal features in ferrous and non-ferrous materials.

This boring bar is suited for small-bore turning applications in job shops, production machining environments, and maintenance-repair operations. Its compact geometry makes it well-matched to Swiss-type lathes, gang-tooled turning centers, and small-bore fixture work where clearance is limited. The left-hand cutting direction supports specific tooling arrangements and climb-cut strategies on compatible turning setups. It is typically installed by machinists and CNC operators working to blueprint specifications on precision components.

Key Features

• Submicron solid carbide construction for rigidity and extended tool life in small-bore applications
• Left-hand cutting direction for compatible tooling orientations and specific lathe configurations
• Minimum bore diameter of 0.2 inches enables work on very small internal features
• Maximum bore depth of 1.3 inches suits a range of shallow to moderate internal bore lengths
• Bright finish coating reduces built-up edge tendency in non-ferrous and softer ferrous materials
• 0.25 inch shank diameter fits standard small-bore toolholders and Swiss-type lathe blocks

Compatibility

Designed as an OEM-style replacement and standard production boring bar for use in 0.25 inch shank toolholders on CNC turning centers and manual lathes requiring left-hand internal boring capability.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for toolholder clamping and overhang. Power down and lock out the machine spindle before seating or removing the boring bar from the toolholder. Minimize shank overhang beyond the toolholder to reduce chatter and deflection during the cut. Verify cutting direction compatibility with the spindle rotation and toolholder orientation before starting the machine.
