Accupro ACC-BB200800A Boring Bar Micrograin Solid Carbide

Product Description

The ACCUPRO ACC-BB200800A is a solid carbide boring bar designed for internal boring operations on lathes and machining centers. Built from micrograin solid carbide and finished with a TiAlN coating, this bar delivers the hardness and heat resistance needed for precision work in steel, cast iron, and hardened materials. It handles a minimum bore diameter of 0.2 inches and a maximum bore depth of 0.8 inches. The 1/4-inch shank diameter and 2.5-inch overall length make it a compact, rigid tool suited for small-bore finishing and semi-finishing passes where tool deflection must be minimized.

This boring bar is intended for use in CNC and manual turning applications where tight bore tolerances and fine surface finishes are required. The right-hand cutting direction suits standard lathe setups. Its compact dimensions make it a practical choice for small-part machining in job shops, production facilities, and maintenance environments where small-diameter internal features are common. Machinists working with Swiss-type, turret lathes, or small machining centers will find the shank size and reach appropriate for toolpost and boring head holders designed for 1/4-inch shank tooling.

Key Features

• Micrograin solid carbide construction for superior rigidity and wear resistance
• TiAlN finish coating for elevated heat resistance and extended tool life
• Right-hand cutting direction for standard lathe orientation
• 0.2-inch minimum bore diameter for tight internal features
• 0.8-inch maximum bore depth suits shallow-to-moderate internal passes
• Compact 2.5-inch overall length reduces overhang and deflection

Compatibility

Designed as a direct-fit replacement or supplemental tooling for boring head holders and toolpost holders accepting a 1/4-inch round shank boring bar in CNC and manual lathe applications.

Installation Notes

Installation should be performed by a qualified machinist following standard toolroom practices. Secure the shank fully within the holder to the recommended engagement depth and confirm runout before cutting. Power down and lock out the machine spindle before changing or adjusting tooling. Refer to the machine tool manufacturer guidelines and applicable shop safety standards when setting cutting parameters.
