The Axminster Optical Centre Punch guarantees to achieve a precise punch location. It consists of a steel holder, two Perspex rods and two hardened steel punches (60° & 90°). The Perspex rods are each engraved on the base, one with a cross hair, the other a bullseye target. The rods take light down and magnify at the same time. Once a rod is aligned with a mark, hold the base firmly and exchange the rod for a chosen punch. A light tap puts an indentation in the precise position. The base is 48mm in diameter with a slip resistant base, the punches and rods are 9.5mm diameter.
