Which component of a drill controls the depth of the hole?

The depth stop is the component of a drill that is specifically designed to control how deep the drill bit will penetrate into the material being worked on. By adjusting the depth stop, an operator can set a specific depth for the hole, ensuring consistency and accuracy when drilling multiple holes or working with materials that require precise hole depths. This feature is particularly useful in construction and woodworking tasks, where the depth of the hole may be critical to the integrity and fit of components being assembled.

The chuck, while essential for holding the drill bit securely, does not influence the depth of the hole. The motor powers the drill and determines the speed and torque but does not affect the hole depth. The trigger controls the operation of the drill, allowing it to start or stop, but it also does not contribute to regulating the depth of the holes created.
