Which tool is referred to as a speed handle?

The term "speed handle" is often associated with tools that enable rapid rotation or adjustments, typically in a socket or wrench application. The correct answer highlights a tool designed for quick operation, which is essential for increasing efficiency during tasks that require frequent tightening or loosening of bolts and nuts.

A speed wrench, for example, is specifically designed for speed and ease of use, allowing the user to turn a socket quickly. This feature makes it beneficial in various settings, such as automotive repair or machinery maintenance, where reducing time spent on repetitive rotations is crucial.

The other choices might refer to tools with specific functions, but they do not capture the essence of speed and efficiency in handling sockets in the way the correct answer does. A hand drill focuses on drilling tasks, the concept of rapid turning socket is somewhat redundant and doesn't typically represent a distinct tool, and a swivel handle is more about movement rather than speed in function. Each of these tools serves important purposes, but in terms of the question's specific focus on a tool characterized by its rapid operational use, the choice identified is the most fitting.
