Accupro ACC-BBL200800 Boring Bar Solid Carbide Left Hand

Product Description

The ACCUPRO ACC-BBL200800 is a solid carbide boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. Built from submicron-grade solid carbide, this bar delivers the rigidity and wear resistance required for tight-tolerance bore work. It cuts in a left-hand direction and accepts a 0.25-inch shank, with a minimum bore diameter of 0.2 inches and a maximum bore depth of 0.8 inches. The overall length of 2.5 inches suits compact toolholding setups. Machinists and toolroom technicians use this bar when bore diameter and depth requirements demand a small-profile, high-stiffness cutting tool.

This boring bar is suited for small-diameter internal turning applications in ferrous and non-ferrous materials. The submicron carbide grade provides consistent edge integrity at higher surface speeds and in interrupted-cut conditions. Its compact geometry makes it a practical choice for production turning, toolroom work, and repair machining where access to shallow, small-diameter bores is required. The bright finish coating reduces built-up edge tendency in ductile materials.

Key Features

• Submicron solid carbide construction for high rigidity and extended edge life
• Left-hand cutting direction for specific toolholding and approach requirements
• 0.2-inch minimum bore diameter for small-bore internal turning
• 0.8-inch maximum bore depth suitable for shallow-bore applications
• 0.25-inch shank diameter fits standard small-bore toolholders
• Bright finish coating reduces built-up edge on ductile workpiece materials

Compatibility

Designed as an OEM-style replacement or direct tooling selection for standard 0.25-inch bore bar toolholders used in CNC and manual turning applications requiring left-hand cut geometry.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the toolholder is de-energized before mounting or changing boring bars. Secure the shank firmly in a compatible toolholder to the holder manufacturer's specified clamping procedure to prevent deflection or pullout during cutting. Do not exceed the tool's rated bore depth, as overhang beyond the maximum depth specification increases deflection and can cause chatter or tool breakage.
