To make your own sealing gaskets from cardboard, paronite, rubber and other materials, sometimes you need a punch to make even, neat holes. Such a tool is not difficult to make with your own hands. It will take no more than an hour to make.

Materials:

  • a drill equal to the diameter of the hole that needs to be cut;
  • machine processing.
