An improved disk cutter or saw laser locator structure is provided with a laser locator on the axle center of a disk cutter or saw driven by a motor, wherein the laser locator consists of a rotary disc and a static disc which share the same axle, a coil is arranged on the axle center of the rotary disc, a magnet ring is arranged on the axle center of the static disc, the magnet ring is concentric with the coil and is relatively arranged outside the coil, and the coil is connected with a laser module arranged on the rotary disc; a sedentary protective cover is arranged outside the disc cutter or saw, a pin penetrating the protective cover is inserted into the static disc to fix the static disc, while the rotary disc has to rotate with the disc cutter or saw, and consequently the magnet ring and the coil make relative movement to generate power for the laser module. The utility model overcomes well-known technical defects and avoids trouble and inconvenience of replacing a battery. In addition, the utility model does not need a switch, thereby avoiding loose contact or damage caused by the switch.
