How do you drill with a cable tool rig?

To drill with a cable tool rig, the process begins by setting up the rig and securing the drill bit on the end of the drill string. The rig's mechanism raises and drops the heavy drill bit repeatedly to break the rock or soil. After each drop, the bit is rotated slightly to create a circular hole, and the cuttings are removed by a bailer or by flushing with water. This cycle is repeated until the desired depth is reached.
