Mindrill heavy duty crawler drill YODHA70  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 70-90 mm wide holes.


The heavy duty crawler drill YODHA70 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.
