ABSTRACT:
A punching device for punching paper and like sheet material contains an upper frame, a cooperating upper magnetic base supporting the upper frame, and a punch rod slideably disposed within the upper frame, and passing through a clearance hole formed in the upper magnetic base. A lower magnetic base contains a punch die. The lower magnetic base which magnetically aligns with the upper magnetic base when a paper sheet is disposed between the upper and lower magnetic bases, and the punch rod is then concentrically aligned with the punch die. This punching device can be used to punch a hole anywhere over the extent of the sheet, regardless of how far the hole is from any edge of the sheet.
