Cordless tools often come in kits which can mean big savings to first-time cordless buyers. Some kits include a cordless drill and saw combination, others offer cordless lights and drills. Some slightly higher-priced kits have two types of cordless saws along with a drill kit. One important difference between cordless kits is voltage. Some are 14.4 volt kits, while others are 18 volts. Some believe the 14.4 volt kits offer a good balance between the power a tool delivers and the weight of the battery. If you need a lightweight cordless tool kit, try out the weight and heft of each tool before purchasing. You may find the 14.4 volt kits work better. You may sacrifice a bit of power or torque, but this may be a fair trade for those in need of lighter tools.
