A variable speed tool is designed to operate at different speeds, allowing the user to adjust the speed according to the specific requirements of the task at hand. This is particularly useful in applications where varying levels of precision or power are needed, such as when drilling or sanding different materials.

Having the capability to change speeds enhances control and versatility, making it easier to achieve the desired results for specific projects. For example, a lower speed can be more effective for delicate or intricate tasks, while higher speeds may be more suitable for removing material quickly.

In contrast, a tool that operates at a constant speed lacks this flexibility and would not be able to adapt to the changing demands of various applications. Similarly, tools that are restricted to only high or low speeds would not provide the broad utility that variable speed tools offer.
