See full text

A drill tool for removing a spot weld from metal includes a housing, a motor mounted in the housing in fixed position relative to the housing, and a bit assembly supported by the housing for movement relative to the housing and the motor between an extended position and a retracted position. The bit assembly is operatively connected to the motor so that the motor can drive rotation of the bit assembly in the extended position.
