The greatest advantage of using a battery-powered ratchet wrench vs manual is the great speed that the electric motor provides. With a maximum speed of 300 RPM, the DeWalt DCF510B will vastly improve your productivity.

The downside of any battery wrench is that it tends to be a bit chunky, limiting your ability to work in tight spaces. DeWalt has done a pretty good job of keeping this this wrench compact. Including the ultra-slim Power Stack battery in the DCF510B kit is great. This battery hardly increases the size of the wrench. It’s most certainly one of the easiest electric ratchet wrenches to use.

The weight balance when using the Power Stack battery is also great. The bare tool weighs around 2.6 pounds. With the battery, it is increased to a little over 3 pounds. Not at all bad. Best of all, the weight is perfectly distributed. You don’t feel the weight of the battery at the back of the tool. Of course, using a conventional, heavier battery won’t be as good.

The sealed, sophisticated glass-filled nylon head, greatly improves durability. It prevents grease and solvents from damaging the ratchet. A grease point is provided to keep the head lubricated, further improving longevity.

The interchangeable anvil system is simple, yet wonderfully effective. You can change between the ³̷₈” and ½” anvils by pressing on the back of the anvil to release it, then easily inserting the other one. The anvils are perfectly locked into position by two detents. When you press the button at the back of the anvil, it simply drops out in an instant. Another great time-saver.

The anvils can slot into either side of the wrench, which may not seem all that significant until you find yourself in a tricky situation. If, for example, you want to remove a fan housing between the radiator and engine, you don’t have much space to fit your hand in to press the trigger. By inserting the anvil into the opposite end of the wrench, the trigger will face away from the engine, giving a more practical position to press the trigger. As always, the guys at DeWalt have thought of everything.

The trigger switch is quite large, wider than two fingers which also gives you more versatility. It has a lock preventing the tool from staring in your toolbox and depleting your battery. The variable speed is incredibly accurate, allowing you to work anywhere between 0 and 300 RPM with only the slightest force from your finger.

The DeWalt DCF510B has a great handle and an LED light. Making this one of the easiest and most comfortable battery-powered wrenches to use.

Power is quite insatiable at 75 FT-LBS nut-busting maximum torque and around 60 FT-LBS for tightening bolts. Okay, when compared to the brutish DeWalt DCF900 impact wrench, this doesn’t seem like much. Rated as the most powerful impact wrench, the DCF900 provides 1,400 Ft-LBS of breakaway torque.

This comparison isn’t exactly realistic. If you need to loosen really tough bolts, an impact wrench is the right tool for the job. If you want to loosen many bolts in the least amount of time, an electric ratchet wrench is better. Placed into the correct context, the power provided by the DeWalt XR ratchet wrench is mighty impressive.

Weighing up the pros and cons, the DeWalt DFC510B comes up mostly pros. In true DeWalt style, this is a tough tool with incredible power. It is well-designed and easy to use. You really couldn’t ask for more. In the form of the DeWalt DCF510B set you get a lot of extra value, thanks to the inclusion of a Power Stack battery, charger, and contractors’ bag at a great price.
