PROBLEM TO BE SOLVED: To provide a chip saw capable of being used for rotations in both directions and reducing shocks against foreign matters in order to remove defects that a blade comes off or is chipped when the blade is oppositely installed as the direction of rotation is usually one way in cutting grasses by a bush cutter. SOLUTION: This chip saw for grass cutters is constituted by halving a circular base metal 1, making sets 3 in all right side teeth in the rotating direction, forming the rear and the left half face 6 to be flat and bringing the rear of the left half face to have the same structure as that of the right half face 7, thus, the chip saw can be used in either left and right rotations and soften shocks to foreign matters. |
