PROBLEM TO BE SOLVED: To provide a pipe cutting tool cutting pipes having different outside diameters by simple work. SOLUTION: This pipe cutting tool has: circular-arc members 121, 122 to be wound around the pipe 999; a first arm 141 supported pivotally on the circular-arc member 121 by a first pivotally supporting part 141a; a second arm 142 supported pivotally on the circular-arc member 121 by a second pivotally supporting part 142a and swinging in the interlocking relationship with swing of the first arm 141 while a part 142c to be abutted is abutted on an abutting part 141c from an outer side; rollers 145, 146 attached rotatably to a first roller mounting part 141b and a second roller mounting part 142b, respectively; and a rotary blade 155 arranged to rotate freely. Consequently, positions where the first arm 141 and the second arm 142 swing are simultaneously adjusted, and pipes having different outside diameters are cut by simple work.
