A burner in the form of a flame jet drill bit engine for liquid fuels is disclosed. The burner has particular utility in a flame jet drill and comprises an axially elongated body with a combustion chamber disposed therein. At least one flame jet nozzle is disposed through the body adjacent the bottom so as to communicate with the reaction chamber. At least one set of water or other liquid jet nozzles is also disposed on the bottom of the body which produce a pulsating water jet at extremely high velocities. The flame jet nozzle and the water jet nozzles are arranged and configured on the bottom of the body so as to be substantially parallel to the axis of the body. By the use of the combination of flame jets and water jets, a cutting means is produced which can cut through a wide range of amorphous and sedimentary rocks.
