What does the term "torque" refer to in power tools?

The term "torque" specifically refers to the twisting force that causes rotation. In the context of power tools, torque is a crucial measurement because it determines how much rotational force is available to turn a fastener or tool head. The effectiveness of many power tools, such as drills or impact wrenches, is often assessed by the amount of torque they can generate. Higher torque values typically mean that the tool can drive larger fasteners or perform more demanding tasks.

Understanding torque is fundamental for selecting the right tool for a specific job. For instance, when working with harder materials or larger screws, a tool with higher torque is essential to ensure proper performance and avoid stripping screws or damaging the material. Thus, in power tools, torque is a key factor in efficiency and capability.
