National 52 In. x 16 Ga. Air Shear - NA5216

The NA5216 Air Shear from National is designed for precise shearing through a full 52 inches of 16 gauge mild steel at up to 40 strokes per minute.  This shear is also recommended for shearing aluminum, plastic, copper, brass, lead and a range of composite materials.  The NA5216 ships with spring actuated hold downs, front sheet supports, manual back gauge, heavy-duty foot switch and a front table square with 1/16" increment length scale.  An optional 57" front squaring arm is available.

The cutting heads on National shears are constructed from D2 steel, a high carbon, high chromium alloy that offers extremely high wear and abrasion resistance.  Both upper and lower blades have been ground and sharpened on all four sides, doubling the working life of the shear versus the more common two-sided blades from other manufacturers.  National machinery offers superior strength and durability with a body constructed of welded steel plates, a much stronger design over the cast iron frames commonly used by the industry.

Made in the USA and backed by a full five year warranty and a lifetime warranty against breakage on the cutting heads and table, the National 52 In. x 16 Gauge Air Shear is expertly built with simplicity in design and the quality that serious fabricators demand.
