What is a dolly commonly used for in a workshop setting?

A dolly is commonly used in a workshop setting to move heavy or awkward objects. This tool is designed to provide mobility for items that are difficult to lift or carry, enabling workers to transport equipment, materials, or tools safely and efficiently. The design typically features wheels that allow it to roll, reducing the strain on workers and minimizing the risk of injury associated with lifting heavy loads.

In contrast, the other options refer to functions that do not align with the primary use of a dolly. For example, holding drill bits pertains to a specific storage or organization solution rather than mobility. Transporting cutting fluids typically requires containers designed to prevent spills, rather than a dolly. Supporting a CNC machine involves providing a stable foundation, which would not align with the moving function of a dolly. Each of these uses is vital, but they do not reflect the main purpose of a dolly in a workshop setting, which is primarily focused on movement and transport.
