Boehm 27mm Hollow Punch Cutter BOEHM HOLLOW / WAD PUNCHES BOEHM Hollow punches, often known as joint-cutters or wad punches, have many varied uses, and can be used for cutting out gaskets and sealing rings in foam, cardboard, leather, rubber, fibre, plastic and lead.

A range of sets are available and each set includes a holder and a range of punches which fit to the holder either singly, for discs or in pairs for washers. All supplied in a case.
