I have several laminate floors where the radiator pipes that pass through them don't have an expansion gap, and at least one pipe is being bent by the laminate pushing against it. What is the best way to cut a circular expansion gap around the pipes in-situ? Is there any kind of tool that's a cross between a pipe slice and a hole saw, that I can clip onto the copper pipe and which will cut a hole in the laminate below? I'm not asking how to cut around pipewok before laying a floor. The floor and pipes are already there.
