The curved profile of the blades means that chains can be cut without any risk of ejection during the operation. Generally used for cutting bars, steel doors or shutters, fences chains, padlocks, cables etc. These cutters can be powered by the Libervit hydraulic units, the Tube and also by the manual pumps. An hydraulic flexible hose is required to connect the hydraulic unit or manual pump to the cutter.
