National Sheetmetal Machines offers four powerful heavy duty cast iron precision hydraulic shears. The hydraulic unit conforms to J.I.C. standards featuring simplicity of design. The National hydraulic system is simple to maintain with stardard replacement parts such as valves, cylinders, hoses and oil. The National shear is actuated by a portable shrouded elecvtric foot switch attached to a long flexible cable so it may be positioned comfortable to the operator.

National Shears have interchangable 4 edged high carbon high chromium blades constructed of premium quality tool steel which will withstand nicking and wear better than releived blades.  National blades are secured to the shear with tempered flat head screws though countesunk holes in the blades.   The high strength cast iron constructed frame is made of the highest tensile strength metal possibled for long life and accurate shearing.  Underdrive construction with downward acting cylinders and major hydraulics under the bed gives the shear a low profile.
