Mindrill YODHA90 crawler drill is a pneumatic crawler drill for drilling with a DTH hammer. It comes with two independent 5 HP propulsion air motors steered with a piston-driven rotary head. Its robust construction, track-mounted frame, and mainframe walking beam oscillator assembly is ideal for drilling in confined areas with rough terrain. The strong 7.5 HP air-powered hydraulic pump ensures high feed force and supreme productivity. The DTH hammer version can drill 90-115 mm wide holes.


The pneumatic crawler drill YODHA90 is a low-cost, effective, and versatile drilling rig that offers great return on investment for a wide range of applications. The compact and lightweight track-mounted frame is ideal for maneuvering over rough terrains and confined areas. It has a versatile feed boom arrangement that allows it to perform drilling in a wide range of angles and orientations.
