It's versatile enough to be used for a variety of applications, such as cutting metal blanks for stamping, creating washers, or even for cutting leather or paper. This tool provides precise and clean cuts, making it ideal for both professional and amateur craftsmen. The punches are machined flat and smooth at the cutting end to create perfect circle-shaped blanks every time, and beveled at the other end for use with a heavy mallet or hammer. To use the disc cutter, remove all punches from the block, and select the size punch you would like. Place your sheet metal in the slot and place your punch, sharp side against the metal, in the correct slot. Strike the beveled side of the punch with a heavy mallet until it pierces through the sheet metal.
