The invention relates to an engineering exploration drill bit capable of pre-warning a buried metal pipeline in advance and a method. The engineering exploration drill bit is formed by organically combining an exploration drill bit, a directional metal induction alarm, a data cable, a data wireless transceiver, a direct-current power supply, a control handbook and a power supply cable, wherein theexploration drill bit is in the shape of a hollow cylinder and the front end of the exploration drill bit is tapered; the directional metal induction alarm is connected in a cavity at the front end of the exploration drill bit; the data wireless transceiver and the direct-current power supply are sequentially connected to the tail end of the inner cavity of the exploration drill bit from bottom to top; the direct-current power supply is electrically connected to the directional metal induction alarm through a power supply cable; the data wireless transceiver is in electrical signal connectionto the directional metal
