The blade is of disc shape, and used for side trimmer the strip or sheets of different materials, various types of longitudinal-cut shears or slitting shears. It performs cutting while is rotating, and is characterized by smooth and straight cut, wear-resistant and impact resistant sharp edge. The blades are made of high-quality tool steel, or alloy tool steel, or high-speed alloy steel according to the material to be cut and working conditions. Circular blade are widely used for the rotary shear, longitudinal-cut shear and slitting shear, as well as the production lines, like, cold-rolling lines, pickling lines, galvanizing line, color-coating line, etc.
