To provide a cutter that cuts off a boundary portion between an underlying metal surface and an old coated film and at the same time completely removes residual wastes of the old coated film adhering to the exposed underlying metal surface by polishing the surface.SOLUTION: A cutter main body 2 is formed into a flat disc shape in which a flat planar bottom surface 4 and a plane surface 5 are formed in a positional relation in which the surfaces are parallel to each other. Inclined surface parts 6 are provided on edges of a whole circumference of the plane surface 5, and the edges of the whole circumference are formed in a sharp shape, in which grinding chips 7 are provided. A mounting shaft 3 is provided at a center of the plane surface 5 of the cutter main body 2. A portion 9 coated with hard abrasive grain coatings is provided on the bottom surface 4.SELECTED DRAWING: Figure 1
【課題】下地金属面と旧塗膜の境界部分を切断すると同時に露出した下地金属面に付着残存する旧塗膜屑を研磨して完全に除去するカッターを提供すること。【解決手段】カッター本体２は、平坦な一面状の底面４と平面５が互いに平行な位置関係に設けられた扁平な円板形状に形成されている。平面５の全周縁には傾斜面部６を設け、全周端縁が尖鋭に形成され、研削チップ７を設けている。カッター本体２の平面５の中心に取り付け軸３が設けられている。底面４には硬質砥粒被膜で被覆されている部分９が設けられている。【選択図】図１
