Cutting Thickness	This disc cutter is suitable for punching soft gold, silver, copper, and brass in thicknesses up to 1.29mm. Note It is not suitable for cutting thin electrode sheets or plastic film, such as the separator of battery
Application Notes	It is suggested to use a urethane square (1/16" thick, 95 durometer, not included) under the cutters as a support as you cut; the urethane absorbs the energy of the hammer blow, protecting the cutters and the work surface and ensuring a clean, sharp cut.
