PROBLEM TO BE SOLVED: To provide a bush-cutting tip saw excellent in its sharpness by preventing the entanglement of plants, reducing the load on an engine of the bush cutter and improving the life of the tip saw itself. SOLUTION: The tip saw for bush cutting is equipped with a disc-shaped seat metal at which central position a mounting hole for the bush cutter is bored, many tip-mounting parts are formed at a prescribed interval at the outer circumferential edge part, and each of tips fixed at the tip-mounting parts is provided with that the outer circumferential edge among the tip-mounting parts adjacently to each other of the seat metal is formed as a straight line state or moderate curved state linear form not deeper than the deepest position of each of the tip-mounting parts, and a distortion-absorbing means consisting of recessed parts and recessed grooves, or the like, is installed at the inside of the outer circumferential edge.
