Accupro ACC-BB140400 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO ACC-BB140400 is a solid carbide boring bar designed for precision internal boring operations on metalworking lathes and machining centers. Built from submicron-grade carbide with a bright finish, it delivers consistent cutting performance in tight-tolerance bore applications. The bar features a right-hand cutting direction, a minimum bore diameter of 0.14 inches, and a maximum bore depth of 0.4 inches. The 3/16-inch shank diameter and 2-inch overall length make this a compact tool suited for small-diameter bore work where rigidity and dimensional accuracy are critical. Machinists and toolroom operators working with small bores will find this bar well suited to production and repair applications.

This boring bar is used in precision machining environments including job shops, toolrooms, and production facilities. It is suited for boring operations in ferrous and non-ferrous materials where a small minimum bore diameter is required. The right-hand cutting direction is the standard orientation for conventional lathe setups. Its compact overall length of 2 inches supports use in close-clearance setups and on smaller CNC turning centers or manual lathes where toolpost space is limited.

Key Features

• Submicron solid carbide construction for improved wear resistance and cutting edge stability
• Minimum bore diameter of 0.14 inches for small-bore applications
• Maximum bore depth of 0.4 inches
• Right-hand cutting direction for standard lathe orientation
• 3/16-inch shank diameter for compatibility with small boring bar holders
• Bright finish coating with no additional surface treatment interference

Compatibility

Designed as a standard right-hand boring bar for use in tool holders accepting a 3/16-inch round shank, compatible with conventional and CNC lathes configured for small-diameter internal boring.

Installation Notes

Installation should be performed by a qualified machinist following standard toolroom practices. Ensure the machine spindle is fully stopped and the machine is powered down before mounting or removing tooling. The bar should be secured firmly in the tool holder with minimal overhang beyond the holder to maximize rigidity and reduce chatter. Refer to the machine manufacturer guidelines and applicable shop safety procedures when setting cutting parameters.
