Power Tool Torque Explained
Torque describes the turning effect applied to a fastener or shaft. In power tools, manufacturers may quote torque figures for drills★, drivers and wrenches, but the way the figure is measured and presented can vary, so direct comparisons require care.
What to look for when choosing it
For a drill★ or driver, consider the fastening size, material, bit type and required control. A clutch can help limit applied torque for suitable applications, while an impact tool delivers torque through repeated impacts. An impact wrench is intended for larger fasteners and should not be treated as a precision torque-setting device simply because it has a high maximum figure.
Matching the tool to the job
If a component requires a specified final torque, use the appropriate torque-control method and follow the equipment or vehicle manufacturer's procedure. Tool torque figures are useful for comparing capability, but they are not the same as a calibrated measurement at the fastener in every working condition.
Accessories, setup and working method
High torque can create sudden reaction forces and can damage fasteners or components if misapplied. Use the correct socket or bit, keep the work secure and follow the manufacturer's operating instructions. HSE guidance also supports selecting work equipment that is suitable for the intended task.
Making a practical choice
For Power Tool Torque Explained, the most useful comparison is the complete working setup rather than a single specification. Consider the material, access, frequency of use, expected finish and the accessories that will be needed. A tool that is easy to control and supported by suitable consumables can be more useful than a larger or more powerful alternative that is poorly matched to the task. Check the manufacturer's current instructions, stated capacities and accessory requirements before purchase and before use. For workplace applications, also consider the suitability, maintenance★, guarding and risk controls that apply to the equipment and task.
