Accupro ACC-BBL100500 Boring Bar Left Hand Solid Carbide

Product Description

The ACCUPRO ACC-BBL100500 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 coating, this bar delivers rigidity and wear resistance in demanding cutting conditions. It features a left-hand cutting direction, a minimum bore diameter of 0.1 inches, a maximum bore depth of 0.5 inches, a 1/8-inch shank diameter, and an overall length of 1.5 inches. Machinists and tool-and-die professionals select this style of bar when working small-diameter bores requiring tight tolerances.

This boring bar is suited for small-bore applications in production machining, tool room work, and precision component manufacturing. Its compact geometry makes it appropriate for use on Swiss-style lathes, turret lathes, and other machine tool setups where clearance is limited. Left-hand cut geometry is used when the tool approaches the workpiece from the right side of the bore or when the spindle rotation requires a reverse-cut configuration. No specific OEM or machine model compatibility is provided by the manufacturer for this SKU.

Key Features

• Submicron solid carbide construction for high rigidity and extended tool life
• Left-hand cutting direction for right-to-left boring passes
• Minimum bore diameter of 0.1 inches enables very small internal features
• Maximum bore depth of 0.5 inches suits shallow-bore applications
• Bright finish coating reduces friction and aids chip evacuation
• Compact 1.5-inch overall length fits tight-clearance machine setups

Compatibility

Designed as an OEM-style boring bar for use in toolholders accepting a 1/8-inch round shank on CNC or manual turning equipment.

Installation Notes

This boring bar is installed by a machinist into a compatible boring bar holder or toolpost that accepts a 1/8-inch shank diameter. Ensure the machine spindle is fully stopped and the tool is clamped securely before starting a cut. Verify that the left-hand cutting geometry matches the intended feed direction and spindle rotation before commencing operation. Follow the machine tool manufacturer guidelines for tool overhang and stick-out limits to minimize chatter.
