Recommended packages
Air compressor match
Mechanical power head rigs drill with mud circulation (e.g. TEC-600J runs a BW1100/6 mud pump). Match the pump to depth and hole diameter rather than an air package.
DTH hammer & bits
Mud rotary method — drill pipes and bits match the power head torque (up to 29 000 N·m on TEC-J series). DTH conversion available on request.
