The primary function of the key bitting array is to display cut possibilities for key creation. This array serves as a systematic way to record and visualize the specific cuts or depths needed on a key blade to correspond with the pin tumblers within a lock. By utilizing the key bitting array, locksmiths can determine the exact measurements required for each cut, ensuring that the resulting key will properly align with the lock mechanism.

This visualization is critical in the key-making process, as it helps locksmiths to create keys that will effectively operate specific locks based on their unique configurations. It also aids in organizing the cuts needed for both original keys and duplicates, making it an essential tool for both precision and efficiency in locksmithing.
