I am building a 3D printer and I have bought steel rods which I'm going to have to cut to size. I have already got a rotary tool at home which works. I have only ever used it to cut wood however, so all the blades I have are specific to wood.
Anyone have any tips on what type of cutting disc is suitable for cutting the steel rods? For reference, the max diameter of these rods is 1.2cm (approx 1/2").
