PURPOSE: Lubricant useful for operation of enlarging the diameter of boiler tube, etc., containing no oil, water-soluble, having rust preventing power, obtained by adding both solid powder lubricant and a rust preventing agent to a pasty material prepared by a polyhydric alcohol, etc. to a polyethylene oxide. CONSTITUTION: A polyethylene oxide having a molecular weight 300W10,000 (preferably 600W4,000) is blended with 5W65wt% polyhydric alcohol, e.g., glycerol, ethylene glycol, etc., and if necessary, with water, to give a pasty material.
