1/4 Hydraulic Shears:
5 Year Warranty - Made in USA
National offers four powerful heavy duty precision hydraulic shears with all steel cutter heads and tables. Standard with hydraulic rubber inserted hold downs, quick adjusting back gauge for direct reading with a positive lock, front arm extensions, table gauges, heavy duty foot switch and well lighted work area. You receive a full three year warranty. The hydraulic unit conforms to J.I.C. standards featuring simplicity of design. The National hydraulic system is simple to maintain with standard replacement parts such as valves, cylinders, hoses and oil. The National shear is actuated by a portable shrouded electric foot switch attached to a long flexible cable so it may be positioned comfortable to the operator.
National Shears have high carbon, high chromium blades with four cutting edges of premium quality tool steel and will withstand nicking and wear better than relieved blades. National blades are secured to the shear with tempered flathead screws through countersunk holes in blades. Complete cuts of full width pieces are 2” longer than specified cutting length. The high strength steel side constructed side frames are made of the highest tensile strength metal needed for long life and accurate shearing. Under drive construction with downward cylinders and major hydraulics under the bed gives the shear a low profile.
