SP-SERIES Remote Hydraulic Cutting Heads connect to any 10,000 psi, high pressure, hydraulic system. Choose from nine different models of production cutters, to help cut costs and efforts. A 3/8″ screw-type male coupler is supplied with each tool. Huskie Tools Cutting Heads have a hinged head which can be opened for easy cable or bar insertion. The movable blade advances in a shear fashion, to cut the material cleanly. When the cutting pressure is relieved an internal ram spring retracts the blade. The guillotine cutting style was chosen over scissor type cutting because of its powerful output force, larger cable capacities, compact size and reliability. NOTE: DO NOT CUT EHS GUY WIRE.
