The present invention is characterized by a device for supplying coolant of a machine tool that supplies coolant to a mist generating device (10) at the tip of a spindle (9) through a coolant supply line (40). A coolant forcing means (11) is provided to the tip of the spindle near the mist generating device to force out the coolant inside a cylinder chamber (21) through a valve path (20). The coolant inside the supply line is repeatedly supplied into the cylinder chamber, whereas the coolant forced out from the cylinder chamber is supplied into the mist generating device at proper pressure. When the coolant pressure inside the supply line is below a fixed level, the coolant inside the supply line flows into the cylinder chamber. When the coolant pressure inside the supply line is over a fixed level, the coolant inside the cylinder chamber is forced out to the mist generating device. According to the present invention, liquid dropping and various bad influences are prevented, and a fixed amount of coolant is intermittently supplied to the mist generating device. Moreover, a proper amount of coolant is timely supplied into the mist generating device by controlling actions of a coolant supply pump.
