The Mincon HDD90 pilot hammer is part of Mincon's comprehensive range of class-leading HDD systems. Thanks to Mincon's advanced design, these systems have a high-frequency cycle that results in smaller chips, resulting in easier hole flushing, less vibration, better steerability, and unmatched production in all hard-rock applications.
