We talked about the torque power earlier in our key features section, and the voltage is also a significant consideration when it comes to the types of jobs your drill will be better at performing. For light indoor DIY work such as putting up curtain poles or constructing the always popular but frequently frustrating flat pack furniture, then a low-power drill will be perfectly adequate. If the projects you intend working on extending to the garden and might include materials such as concrete and paving slabs then the higher the voltage, the better to handle these heavy materials.\r
