ABSTRACT:
A portable hand-held device for code cutting notches in a key blank by a punching mechanism permits quick and easy modification to accommodate key blanks of different configurations and keys requiring different notch depth, notch spacing and notch angle. A key-gripping vise slidably held by a carriage moves transversely to the punch to achieve proper notch spacing. The carriage is controllably moved to different heights above the punch by detents in a circular drum, whereby the depth of the notch is determined. The punch rod and matching anvil may be replaced to achieve a different notch angle.
