  • Patent number: 9902001
    Abstract: A table saw includes a base, a work table having a cutting opening, a tank for receiving cooling liquid, a blade partly extending out from the cutting opening, and a guard assembly. The guard assembly includes a guard for covering the blade and for moving upwards under the action of a workpiece. In a working condition, at least a portion of the guard abuts against the workpiece, and the workpiece can slide relative to the guard. The guard has a guiding wall which abuts against the workpiece in the working condition and which guides the cooling liquid into a kerf in the workpiece formed by the blade. The table saw effectively controls the cooling liquid splashed during the cutting operation of the workpiece and prevents the cooling liquid from splashing to dirty the operator, the work table, and the workpiece.
