Using an angle-grinder and protective gear for hands, eyes and ears, cut just below the rim taking care to not cut the second layer of the metal sheet. That way, the lid can be replaced. A metal saw also works very well. Tip: Start with using an angle grinder (for easiness) and finish with the saw (for precision). Remember to protect the ground with tarpaulin as the remnants of liquid in the drum may leak out from the area you are cutting.
