Problems in small diameter hole machining predominantly stem from unstable chip evacuation. AD-MICRO addresses this issue with cutting edge specifications and flute geometry optimized for small diameter applications, enabling the formation of stable chip shapes—even with external coolant—and ensuring reliable uninterrupted machining. ADO-MICRO’s unique oil holes and flute geometry enable stable and high efficiency processing in small diameter deep-hole applications. Non-step drilling is made possible even for deep-hole applications, with approximately 9 times the machining efficiency versus step drilling.
