Micro 100 BB-200600 Boring Bar Right Hand Cut

Product Description

The MICRO 100 BB-200600 is a right-hand cut boring bar designed for precision internal boring operations on the lathe or machining center. With a minimum bore diameter of 0.2 inches and a maximum bore depth of 0.6 inches, this tool is suited for small-diameter finish and semi-finish boring work where tight tolerances are required. The 0.25-inch shank diameter mounts into standard toolholders, and the 2.5-inch overall length keeps the setup compact and rigid. Machinists and toolroom operators use this bar when a drill alone cannot achieve the required diameter accuracy or surface finish.

This boring bar is intended for use in manual lathes, CNC turning centers, and small machining centers where small-bore precision work is common. Typical applications include finishing pre-drilled holes to exact diameter, truing bores in small workpieces, and light material removal on ferrous and non-ferrous stock. The right-hand cutting direction is the standard orientation for conventional lathe setups. It is commonly used in job shops, maintenance shops, and production environments requiring consistent small-bore accuracy.

Key Features

• Minimum bore diameter of 0.2 inches suits small and tight-tolerance bore work
• Maximum bore depth of 0.6 inches for short, controlled cuts
• Right-hand cut orientation compatible with standard lathe and turning center setups
• 0.25-inch shank diameter fits common toolholders and boring bar holders
• Compact 2.5-inch overall length reduces overhang and improves rigidity

Compatibility

Designed as an OEM-style replacement and standard fitment for toolholders and boring bar holders accepting a 0.25-inch shank diameter in manual and CNC turning applications.

Installation Notes

Installation is performed by a machinist or toolroom technician. Secure the shank firmly in the toolholder to the manufacturer-specified clamping method before operation - do not leave the bar with excessive overhang beyond what the bore depth requires, as this increases chatter risk. Power down and lock out the machine spindle before setting or adjusting the tool. Verify bore diameter with a calibrated gauge after the first pass before proceeding to final depth.
