What does torque refer to in electric drills?

Torque in electric drills refers to the power to maintain rotation under pressure. This is a crucial characteristic, especially when drilling into tougher materials where resistance may require the drill to exert more force to continue turning the bit. Higher torque ensures that the drill can handle such resistance without stalling, allowing for consistent and effective drilling performance.

The amount of torque available in a drill can significantly affect its functionality, determining how well it can operate under various conditions, including different materials or when applying pressure during use. This makes understanding torque essential for users who need to select drills based on the tasks they are performing.

In contrast, speed, heat generation, and size of the drill bit are separate aspects of drill operation and functionality. While speed can influence how quickly a task is completed, it does not directly relate to the drill's ability to maintain rotation when faced with resistance. Similarly, heat generation can occur as a result of friction but is not related to the torque itself, and the size of the drill bit pertains to the diameter of the hole being drilled rather than the power or effectiveness of the drill's motor under load. Therefore, understanding torque allows users to choose the appropriate drill for their specific needs.
