The first thing to note in favor of this tool is it’s weight. With 3.4 pounds, the drill is quite lightweight and therefore it will be easy for you to operate. At 6.9 inches from front to back, this product is very handy and small enough to grab easily in your hand. Furthermore, you will find the center of gravity right above its grip so that it stays balanced while you are working. So gone are the days when you had to put a lot of effort on a pistol grip drill that is hard to operate and feels unbalanced. The smaller grip and good balance offer a great combination that makes it stand out compared to many other products.


Another notable feature this drill has to offer is that it has a brushless motor which makes it more power efficient. A brushless motor will run double the amount of time on a single charge, and yes will run cooler and and smoother compared to an ordinary brushed motor. The drill features two-speed transmission settings which make your drilling speed more flexible. Low speed will run up to 550 RPM whereas high speed will run up to 2000 RPM, versatile enough to get a wide range of jobs done.

General Performance

With a 0.5-inch ratcheting chuck which is all metal and very well-made, the drill bit is not only gripped firmly but also very easy to clutch tightly. Working in a dim lighted space will be a cinch, as there are three LED lights to guide your grip. With an adjustable torque setting and the great brushless motor, you will find a tool that has an outstanding performance and battery life. The DCD791D2 comes with 2.0 Ah XR Li-Ion battery packs, Charger, Kit Box, and a nice belt hook, so carrying it around will be a non – issue.
