ABSTRACT:
A key cutting apparatus having an arrangement for assuring substantially complete removal of cutting chips. A rotary cutting blade which engages a clamp held key is housed within an outer housing which is connected to a vacuum tube to draw off chips. In the front, in the vicinity where the cutting blade engages the key, a pair of sliding doors are provided, one on each side of the housing. These doors are spring biased forwardly into mating engagement with the front jaw surfaces of the clamp to seal off the two sides while permitting continued forward movement of the cutting blade, under the action of the spring, to effect cutting of the key. A flap may be provided to close off the top of the space between the two doors.
