ABSTRACT:
A device for quickly and accurately determining the depth of cuts in a key, and for other depth determinations associated therewith. This device has a fixed anvil member having a flat top surface, as a reference surface, with a transverse slot to accept a second edge of doubly-cut key. A tip member having a selected configuration is biased toward this reference or "zero position" surface. Deviation of the tip member away from this reference surface is displayed in a visual manner on a dial indicator, a digital readout indicator or the like. The dimensioning of all the cuts of a key can be performed in seconds to accuracies of about 0.0005 inch. The cuts to be dimensioned can be in edges of the key or in flat side surfaces. Also, the pins of a lock tumbler can also be dimensioned with the embodiments of the invention.
