Buying a drill sounds simple — until you start comparing your options. Every DIYer and professional tradesperson quickly realizes there are many factors to weigh before shopping for an electric drill, with plenty of factors to weigh: from power output and runtime to mobility and project type. One of the first questions you may ask is: should you choose a corded drill or a cordless drill? Your answer mostly depends on how and where you plan to use it. If you only need a drill for assembling furniture, installing shelves, or completing occasional DIY projects around your home, convenience will likely be your top priority.
