If the drawings of condenser of heat exchanger cannot be found to get accurate tube I.D. information the butt end of a drill bit can be used. The butt end of the drill bit should be inserted past the expanded part of the tube. The drill bit should not be forced into the tube. When a drill bit fits in snugly the size of the drill bit is the I.D. of the tube to be cleaned and the size of the tube cleaning tool to be used.
