PURPOSE: A cooling structure using cutting oil of a turret tool rest for a rotary tool is provided to efficiently and rapidly cool a tool holder and a gear box by forming cutting oil passages inside the tool holder or the gear box. CONSTITUTION: A cooling structure using cutting oil of a turret tool rest for a rotary tool comprises one or more cutting oil passages(102). The cutting oil passages are formed in a tool holder(100) or gear box coupled to a turret tool rest. Cutting oil passes through the cutting oil passages. Heat generated in the tool holder or the gear box is cooled by the cutting oil passing through the cutting oil passages.
