Shear (sheet metal) allowing great flexibility in shapes that can be cut. Sheet Metal Press Brake Shear (sheet metal) There are many types of shears used to shear sheet metal.

It is usually used for cutting rough shapes out of medium-sized pieces of sheet metal, but cannot do delicate work. For the small shear, it mostly designed for a wide field of applications. Light weight and easy efficient operation, yet very sturdy in construction. The cutting blades fitted are carefully
