Hydraulic nut cutter are tools designed to remove old and rusty nuts that are no longer useful from machinery. In some cases, nuts can become tightly jammed on fastener threads due to factors such as corrosion, making them extremely difficult to remove. Nut splitters are manual hand tools that are used with a ratchet wrench, socket, or spanner to effectively break free these stubborn nuts. Nut Splitters are often considered as a last resort when other methods have been unsuccessful.
