A brake is a device that allows you to bend a piece of sheet metal at a particular angle. Most frequently expensive sheet metal bending tools called brakes are used to bend sheet metal but you can also complete this task without one. Bending sheet metal by hand is a manageable task if the piece of sheet metal is small and thin enough to handle. The force must exceed the material s yield strength to achieve a plastic deformation.
