Accupro ACC-BBL100700 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO ACC-BBL100700 is a solid carbide boring bar designed for internal bore finishing and sizing operations on small-diameter features. Built from submicron-grade carbide, it delivers the rigidity and wear resistance needed for tight-tolerance work in hardened and abrasive materials. The left-hand cutting direction suits specific spindle orientations and tooling configurations where a standard right-hand bar cannot be used. With a 0.1-inch minimum bore diameter and a 0.7-inch maximum bore depth, this bar targets fine, precise holes in precision machined components. It is used by machinists and tool-and-die technicians on CNC turning centers and manual lathes.

This boring bar is suited for small-bore applications in precision machining environments, including production shops, tool rooms, and job shops. The 1/8-inch shank diameter allows it to fit into compatible toolholders designed for small-shank boring tools. At 1.5 inches overall length, it is compact and appropriate for close-clearance setups. It is commonly applied when machining non-ferrous metals, hardened steels, and other demanding workpiece materials requiring consistent bore geometry and surface finish.

Key Features

• Submicron solid carbide construction for superior hardness and edge retention
• 0.1-inch minimum bore diameter for fine, small-bore applications
• 0.7-inch maximum bore depth for shallow-to-moderate bore operations
• Left-hand cutting direction for reverse-spindle or specific toolholder setups
• Bright finish coating for reduced friction and improved chip flow
• Compact 1.5-inch overall length for close-clearance machining

Compatibility

Designed for use with toolholders accepting a 1/8-inch shank boring bar in CNC turning centers and manual lathes configured for left-hand cutting operations.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and all power is isolated before mounting or removing the boring bar. Secure the shank firmly in the toolholder to the manufacturer-specified clamping method to prevent chatter or pullout during cutting. Verify spindle rotation direction matches the left-hand cutting geometry of this bar before initiating any cut.
