The 4-piece, pump-hydraulic nut splitter set is used for splitting non-detachable, rusted or overtightened nuts of all grades. The threaded pin remains undamaged during this blasting process. The special TiN coating of the chisel has particularly good frictional properties, enabling a high cutting performance to be achieved with little effort. The nut splitter set is used in the commercial vehicle, pipe industry, tank cleaning, petrochemical industry, steel and mining sectors. The pump hydraulics guarantee an enormous cutting force of up to 90 tonnes. The set contains: a pump-hydraulic nut splitter, a replacement chisel and two hexagon socket spanners for replacing the chisel.
