These characteristics are important as they determine how easy the drill is to handle and how tight a space it can fit into. Size and WeightĭeWalt drills vary in size and weight. UWO is a value created by DeWalt, so one won’t find it being used to rate any other brand of tool. Instead, the manufacturer rates its drills by a value it calls unit watts out (UWO), which is a calculation that combines torque and speed to rate the overall power of the drill. A drill with high torque can drive larger bolts and other fasteners into the wood, while a drill with low torque might struggle to attach two 2x4s together with a 2.5-inch screw.ĭeWalt does not list the torque for its power drills, as the company believes it is not a good indication of performance. Torque is a measure of the maximum amount of turning force the drill can produce when turning at low speeds.Speed determines how quickly the drill will drive screws in, which can be crucial for a project that requires one to drive in dozens or even hundreds of screws. Speed is measured in rpm and delineates the maximum speed at which the drill chuck can spin.The two values that describe the cordless drill’s power are speed and torque. Hence, DeWalt’s brushless corded drills are significantly more expensive than its brushed models. Brushless motors are also more expensive to make. And, since it produces less friction, brushless motors have a longer lifespan than their brushed brethren. By producing less friction, a brushless motor can handle more current without overheating, allowing it to reach a higher rpm and greater torque than a brushed motor.Ī brushless motor is more energy efficient, allowing it to run up to 50 percent longer on a single battery charge than a brushed motor. Brushless motors produce less friction than their brushed counterparts, and this has several advantages. MotorĪs with many tool manufacturers, DeWalt’s drills come in both brushed and brushless motors. DeWalt’s line of cordless drills includes conventional 12-volt and 20-volt drills and specialty angle and hammer drills. However, the battery adds weight, so cordless models typically weigh more than corded drills. Whereas a corded drill is tethered to a 120-volt outlet, one can take a cordless drill virtually anywhere. The advantage of a cordless drill is its portability. DeWalt makes ⅜-inch and ½-inch corded drills. Corded models also have access to a constant supply of electricity, so there’s no need to worry about battery life and recharging needs. Corded models must be plugged into a 120-volt power outlet, while cordless models take their power from lithium-ion batteries.Ī corded drill, with its access to a 110-volt power supply, can produce greater torque and speed than a corded model, which is limited to a 20-volt power supply. Power SourceĭeWalt offers two types of drills-corded and cordless. Ahead, learn more about how DeWalt rates its drills and other characteristics that are important to keep in mind when shopping for the best DeWalt drill.
