Application Areas

This portfolio supports operations from light quarrying to complex tunneling. Rod types vary by length and configuration, including rubber-collared and drifter styles, to suit soft through ultra-hard rock. Shank-end models are also available for abrasive conditions requiring greater impact tolerance.
