Not used this particular tool from CK, but I have a no brand set of ratchet cutters which will cut 120mm SWA cores all day long. The spec from CK states up to 52mm dia Cu or Al and 36mm SWA, so I can't imagine you'll have any issues. The only thing I find my cheap set struggling with is fine stranded and I need to be careful with the last part of the cut through tri-rated cable.
