PROBLEM TO BE SOLVED: To provide a bush-clearing tip saw having increased durability of the blade to suppress the lowering of the sharpness of the tip saw by fixing a plurality of tips to a blade part in a prescribed manner, effective for improving the bush-clearing efficiency and capable of prolonging the life of the saw. SOLUTION: The bush-clearing tip saw has a round disk form having a hole for attaching to a bush clearer at the center, blades and blade cavities alternately arranged on the outer circumference of the disk, and tips fixed to the blades. The tips are fixed to a plurality of tip-attaching parts of the blade part in a manner to position the tip end of the tip outside of the blade cavity. Each tip fixed to each of the plural tip attaching parts is fixed in a manner to form its tip end with a prescribed step, and the step is designed such that the rear tip in the rotation direction of the base is positioned outside of the front tip.
