Patent ID: 8042442

Claim:
A cutting tool for cutting steel sheet billets, comprising: a blade holder; a cutting blade fastened to the blade holder; and a pressure cushion which is arranged on a blade side of the blade holder and adjacent to a side of the cutting blade, wherein, the steel sheet billets are supported by a continuous firm support on a side away from the cutting blade in an area opposite the cutting blade such that when the cutting blade is proceeding through the steel sheet billet, steel sheet billet material cannot flow toward the continuous firm support, when the cutting blade penetrates into a material to be punched during a punching stroke, the pressure cushion is pressed on a side of the cushion opposite a side facing the material to be punched in an area of a useful punched part, and the pressure cushion and the cutting blade are arranged such that as the pressure cushion is pressed against the useful punched part, the pressure cushion presses laterally against the cutting blade, such that as the cutting blade proceeds through the material to be punched, the pressure applied by the pressure cushion in a lateral direction causes an increasing elastic deflection of a cutting edge of the cutting blade.
