Accupro ACC-BB080500 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO ACC-BB080500 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, it achieves a minimum bore diameter of 0.08 inches and handles bore depths up to 0.5 inches. The right-hand cutting direction suits standard spindle setups. At 1.5 inches overall length with a 0.125-inch shank diameter, this bar is sized for tight-clearance work where rigidity and dimensional accuracy are critical. Machinists and toolroom technicians rely on submicron carbide for its resistance to edge wear in small-diameter applications.

This boring bar is suited for small-bore internal turning on ferrous and non-ferrous workpieces where entry diameters are restricted. It fits standard 0.125-inch shank tool holders and is a practical choice for production shops, toolrooms, and job shops running tight-tolerance bores in materials ranging from aluminum alloys to hardened steels. The bright (uncoated) finish makes it easy to inspect for wear and regrinding candidates.

Key Features

• Submicron solid carbide construction for high wear resistance in small-diameter boring
• Minimum bore diameter of 0.08 inches for restricted-entry applications
• Maximum bore depth of 0.5 inches suitable for shallow precision bores
• Right-hand cutting direction for standard spindle rotation setups
• Bright (uncoated) finish for easy visual wear inspection
• Compact 1.5-inch overall length with 0.125-inch shank for tight-clearance tooling setups

Compatibility

Designed for use with standard 0.125-inch shank boring bar holders on CNC and manual lathes configured for right-hand internal turning operations.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully stopped and the lathe is powered down before changing tooling. Secure the shank firmly in the tool holder to the appropriate clamping force recommended by the holder manufacturer to prevent chatter and deflection. Verify bore entry clearance against the minimum bore diameter specification before beginning a cut.
