To provide a bush-cutting tip saw that can sufficiently increase safety in the bush-cutting work, by integrally arranging a plate body of a circular outer diameter capable of preventing the tip from coming in direct contact with the ground in the anti-bush-cutter mounting face side of the base metal.SOLUTION: A bush-cutting tip saw is characterized in that a plate body of a circular outer diameter having the outer diameter being smaller than the outer diameter of the base metal by a predetermined size and having a predetermined gap between the base metal and itself at least in the tip side is integrally arranged in a predetermined size outer circumferential side of a mounting hole for a bush-cutter, in the anti-bush-cutter mounting face side of the base metal. The base metal includes a mounting flat part formed of the mounting hole for the bush-cutter, a step difference part formed while protruding toward the bush-cutter side in the outer circumferential side of the mounting flat part, and a cutting edge flat part extended substantially in parallel with the mounting flat part toward the outer peripheral edge direction of the base metal in the outer circumferential side of the step difference part. The plate body is arranged substantially in parallel with the cutting edge flat part in the outer circumferential side end of the mounting flat part.SELECTED DRAWING: Figure 4【課題】チップの地面への直接的な接触を抑制可能な外径円形の板体を、台金の反刈払機取付面側に一体的に配設することにより、刈払い作業時の安全性を十分に高め得る刈払い用チップソーを提供する。【解決手段】台金の反刈払機取付面側で刈払機用取付孔の所定寸法外周側に、その外径が台金の外径より所定寸法小さく少なくともその先端側において台金との間に所定の隙間を有する外形円形の板体を一体的に配設したことを特徴とする。前記台金は、刈払機用取付孔が形成された取付平坦部と、該取付平坦部の外周側に刈払機側に向けて突出する状態で形成された段差部と、該段差部の外周側に台金の外周縁部方向に向けて取付平坦部と略平行に延設された刃先平坦部とを備え、取付平坦部の外周側端部に板体が刃先平坦部と略平行に配設される。【選択図】図４
