CMR-1000 is designed for multi-purpose drilling, and is a high capacity, heavy duty multi-purpose drill rig which is highly effective in diamond coring, reverse circulation and rotary drilling techniques. Axial pressure works against the upward force when the air hammer pushes down the pistons, ensuring the drilling force efficiently passing through the pipe to the bit. When using air hammer drilling, the speed is 15-30 rpm.
