Some 2-hole punches have an "888" marking on their paper guide, to assist punching all four holes into A4 paper. [ 5 ] Konica Minolta specifies that for European 4-hole arrangements, all holes should be 11 ± 1 mm from the nearest (i.e. long/spine) edge of the paper, [ 6 ] which is slightly at variance with ISO 838's specification of 12 ± 1 mm .
A transfer punch is a punch (usually in an index set) of a specific outer diameter that is non-tapered and extends the entire length of the punch (except for the tip). It is used to tightly fit the tolerances of an existing hole and, when struck, precisely transfer the center of that hole to another surface.
A leather punch is a hole punch specifically for making holes in leather. The working tip of the punch is a hollow steel cylinder with a sharp circular knife-like edge. The leather piece is placed on a hard surface, which may be a part of the tool set, and the punch is forced through it, cutting out a small circular piece which is discarded.
Usually, the punch and die are close to the same dimensions, creating a sheared edge when they meet. A punch that is significantly smaller than the die can be used to produce an extruded hole where the punch displaces the punched material to the sides, forming a tube perpendicular to the punched sheet.
