Shear (sheet metal)

They are generally used to cut ferrous members, such as rebar, pipe, angle iron, or I-beams.

It is usually used for cutting rough shapes out of medium-sized pieces of sheet metal, but cannot do delicate work.

It is electrically welded together to make it a sturdy stable unit capable to withstand highest stresses due to heavy duty usage.

The footplates are reinforced with bracing angles so that they give firm stability to the shear.

Setting the blade on an angle decreases the amount of force required, but increases the stroke.

The shear table is the part of the machinery that the workpiece rests on whilst being shorn.

The upper and lower blades are the piece of machinery that actually do the cutting, while the gauging device is used to ensure that the workpiece gets worked where it is supposed to be.

Typical workpiece materials include aluminum, brass, bronze, and mild steel because of their outstanding shearability ratings.

Snips, also known as shears, are hand tools used to cut sheet metal and other tough webs.
