Micro 100 BB-200800 Solid Carbide Boring Bar Right Hand

Product Description

The MICRO 100 BB-200800 is a solid carbide boring bar designed for precision internal boring operations on CNC and manual lathes. It features a 0.2 inch minimum bore diameter and a maximum bore depth of 0.8 inches, making it suited for tight, shallow bore work where rigidity and dimensional accuracy are critical. The uncoated solid carbide construction provides excellent wear resistance and maintains edge integrity at elevated cutting speeds. A 0.006 inch corner radius delivers a controlled surface finish on ferrous and non-ferrous workpiece materials. Machinists and tool-and-die professionals working in production and job-shop environments rely on this geometry for repeatable, close-tolerance results.

This boring bar is used in machine shop applications requiring precise bore sizing in small-diameter work. The right-hand cutting direction suits standard lathe setups running conventional spindle rotation. The 0.25 inch shank diameter fits common boring bar holders and quick-change toolpost systems. The 2.5 inch overall length provides sufficient reach for most shallow-bore applications without sacrificing stability. Typical users include CNC machinists, manual lathe operators, and toolmakers performing finish boring, sizing, or cleanup passes on pre-drilled or rough-bored features.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding bore operations
• 0.2 inch minimum bore diameter supports small-diameter internal work
• 0.8 inch maximum bore depth suited for shallow through and blind bore applications
• Right-hand cutting direction for standard lathe spindle rotation
• 0.006 inch corner radius for controlled surface finish and reduced stress concentration
• Uncoated finish allows direct use on a broad range of workpiece materials

Compatibility

Designed for use with standard 0.25 inch boring bar holders and quick-change toolpost systems on CNC and manual lathes configured for right-hand turning operations.

Installation Notes

Installation is performed by qualified machinists following standard toolroom practices. Ensure the machine spindle is fully stopped and the lathe is powered down before mounting or adjusting the boring bar in its holder. Confirm the shank is clamped securely with adequate contact length to prevent chatter during cutting. Follow the machine tool manufacturer guidelines for tool overhang and depth-of-cut limits when working at or near the maximum bore depth.
