A built-in LED lamp provides visibility in dark. The higher a drill’s Power Rating, or UWO, the faster it will perform on the jobsite. OVERALL SCORE RANKED 9 of 20 Drilling - 35 8.5 Driving - 35 7.6 Battery Life - 20 6.8 Convenience - 10 6.3 RELATED: Best Drills of 2023 Our Verdict Scoring in the upper portion of the group in our best drill review, the DeWalt Atomic DCD708C2 is an overall excellent cordless drill. This cordless drill driver has 20 torque clutch settings to handle drilling tasks around the home and shop. The drill’s Power Rating is measured by its Units Watts Out (UWO), the point where the drill’s speed and torque output are the highest. It is not until now that it will be used as new way of evaluating a drill’s performance level, and is a direct indication of how fast it will complete an application. Measures drill speed and torque with multiple data pointsĪ drill’s Power Rating has been used for many years as a tool to design products.Measures drill torque level at 0 rpm (does not measure speed) DeWalt Cordless Drill / Driver Kit DCD771C2 Specs Battery, Maximum initial battery voltage (measured without a workload) is 20 volts.LED foot light for superior visibility View more features Product Overview Unlock powerful performance in a compact size with the ATOMIC 20V MAX 1/2 in. front to back designed to fit in tight spaces Lightweight at only 2.4 lbs. Power is the amount of work completed in a given period of time Buy Now Add to Wishlist Compact at only 6.3 in.Torque is the force the drill produces to turn an object.Speed is how fast the drill turns (revolutions/minute).K is constant and varies depending on the units used to measure torque.Power is measured by the formula: Speed X’s Torque/K = Power.Power can be measured by the ability of a device to produce work. ![]() A new way to measure the performance of a drill is to combine speed and torque, a measurement called Power. The DeWalt DCD985M2 features an all-metal transmission system that gives users 3 variable speed settings. In recent years torque ratings have been steadily increasing to levels beyond what is actually needed to complete applications. Torque is the force the drill produces to turn an object, not how fast an object will turn. A common misconception is: the higher the torque rating, the faster the drill will complete an application. The key to drill performance is being able to deliver the required torque at the highest speed.
