The boring bit is formed of the inner bit and the bore-expanding lost bit. The inner bit allows driving force, rotational force, and thrust to be transmitted thereto from a boring device via the inner pipe rod, and blows out a fluid supplied via a hollow portion of the inner pipe rod. Further, the inner bit functions to take in excavated earth to a gap between the outer pipe rod and the inner pipe rod, and to propel the outer pipe rod while inversely discharging the earth out of the bore. The bore-expanding lost bit is permanently placed on a bottom of the bore. Further, the inner bit has a non-circular shaft portion, and the lost bit has a non-circular hole conforming to the non-circular shaft portion. Then, the non-circular hole of the lost bit is fitted onto the non-circular shaft portion of the inner bit, whereby the lost bit is coupled to the inner bit in a manner irrotational and axially movable with respect to the inner bit.  <P>COPYRIGHT: (C)2003,JPO
