How to select the right MICRO 100 boring bar for your application?

Select the MICRO 100 boring bar based on shank diameter matching your tool holder, workpiece material, and required bore depth. For small bores, the 3/16 in shank is ideal. Consider coating needs: bright (uncoated) suits general machining. Right-hand tools cut when feeding toward the chuck. Consult your application engineer for chipbreaker selection.
