What is defined as the "Maximum Adjacent Cut Specification" in locksmithing?

The minimum cut allowed on any key
The maximum allowable difference between adjacent cut depths
The maximum cut allowed for a specific key profile
The specification for pin heights in a lock cylinder

The correct answer is: The maximum allowable difference between adjacent cut depths

The "Maximum Adjacent Cut Specification" in locksmithing refers to the maximum allowable difference between adjacent cut depths on a key. This specification is crucial in the key cutting process to ensure that the key will properly operate the lock it is intended for. Maintaining the appropriate depth differences between adjacent cuts helps to prevent issues such as key jamming or failure to turn within the lock mechanism. In locks, especially pin tumbler locks, the heights at which pins must be set relative to the cuts on the key directly affect the lock's functionality. If adjacent cuts on the key vary too greatly in depth, it may create excessive play when the key is inserted or possibly hinder the locking mechanism's operation. Therefore, understanding and applying the Maximum Adjacent Cut Specification is essential for locksmiths to ensure keys are cut accurately and reliably for optimal lock performance.
