Micro 100 BB-200500 Solid Carbide Boring Bar Right Hand

Product Description

The MICRO 100 BB-200500 is a solid carbide boring bar designed for internal diameter boring operations on CNC lathes and manual turning centers. It features a right-hand cutting direction and a minimum bore diameter of 0.2 inches, making it well suited for tight-tolerance small-bore work. The 0.006-inch corner radius supports fine finishing cuts, and the one-piece solid carbide construction delivers rigidity and vibration resistance that high-speed machining demands. Machinists and toolroom technicians working in production or job-shop environments will find this bar appropriate for steel, stainless, aluminum, and similar materials where precise bore geometry is required.

This boring bar is used in turning operations where a small minimum bore diameter is critical. With a 0.25-inch shank diameter and a 2.5-inch overall length, it fits standard boring bar holders and quick-change toolposts commonly found on smaller CNC and manual lathes. It is appropriate for both production runs and prototype work where achieving accurate bore size and finish in a single or multi-pass operation is the goal. The right-hand cut orientation suits conventional front-facing tool setups.

Key Features

• Solid carbide construction for rigidity and extended tool life in demanding bore operations
• 0.2-inch minimum bore diameter allows work in tight, small-diameter bore applications
• 0.5-inch maximum bore depth suitable for shallow to moderate through and blind bore jobs
• 0.006-inch corner radius supports fine finishing and close-tolerance work
• Right-hand cutting direction for standard lathe toolpost orientation
• 0.25-inch shank diameter fits common boring bar holders and quick-change systems

Compatibility

Designed as a standard solid carbide boring bar with a 0.25-inch shank, compatible with boring bar holders and quick-change toolposts sized for 0.25-inch shank tooling on CNC and manual turning centers.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the spindle before seating or removing the boring bar from the holder. Ensure the shank is fully supported in the holder with minimal overhang to reduce chatter and deflection during the cut. Follow the machine manufacturer and shop safety guidelines for tool clamping torque and insert or bar extension limits.
