[PROBLEMS] It can be used under severe wire drawing conditions under high temperature, high pressure, and high speed, and can be used to reduce the diameter from a narrow diameter to a large diameter and to a wide range of wire speeds from low speed to high speed. Even without the use of harmful boron-containing compounds such as borate, borate-containing dry elongation can be achieved with lubricity, followability, spreadability, adhesion, heat resistance, workability, workability, durability, etc. Provided is a borate-free dry-drawing lubricant that has high performance equal to or better than that of a wire lubricant and that is safe for the environment and the human body. A boric acid-free dry wire drawing lubricant comprises 30 to 90% by weight of a saturated fatty acid metal soap, 10% of a water-soluble inorganic condensation compound not containing boron, and / or its condensation precursor compound. -40% by weight is included.
