The invention relates to the technical field of mechanical processing, in particular to a tool main cooling nozzle, a tool cooling device and a dicing saw. The tool main cooling nozzle comprises a fixed portion, a rotating portion and a blocking structure. The rotating portion comprises a main spray pipe for injecting a cooling medium from the front side of a blade toward the blade. The rotating portion is rotationally mounted on the fixed portion around the axis extending in the axial direction of the blade so that the end, facing the blade, of the main spray pipe can swing toward and away from the blade. The blocking structure limits the range in which the end, opposite to the blade, of the main spray pipe swings away from the blade to prevent the end, opposite to the blade, of the mainspray pipe from colliding with a workpiece to be processed. The blocking structure can limit the range in which the end, opposite to the blade, of the main spray pipe swings away from the blade to avoid the situation that the
