Final answer:
Pipe cutters do not remove any metal as they work by scoring the pipe surface and creating a groove, rather than actually removing material.
Step-by-step explanation:
Pipe cutters are tools used to cut through pipes without removing any metal. They work by using a cutting wheel to score the surface of the pipe, creating a groove. As the cutter is rotated around the pipe, the groove gets deeper until it penetrates through the pipe wall and the pipe is severed. The pressure applied by the cutter is enough to create the groove and cut through the pipe, but it does not remove any metal.
