A Disc Tumbler Lock is a type of locking mechanism that uses rotating discs to secure a door or container. Instead of traditional pins, this lock features a series of flat, circular discs that must be aligned correctly to allow the lock to open. When the correct key is inserted, it rotates the discs to the right position, enabling the lock to turn. These locks are often found in high-security applications, such as safes and vaults, due to their resistance to picking and manipulation. The design makes them more difficult to bypass compared to standard pin tumbler locks, enhancing overall security.
