![]() ![]() There are also smaller ⅜- and larger ¾-inch drive models, with the latter being for heavy vehicle maintenance, agricultural equipment, or other industrial uses.Īmong half-inch impact wrenches, there are also tool body sizes-generally, full, compact, and sub-compact. What are we talking about when we say size? The most common size impact wrenches are ½-inch drive models-those with a square anvil measuring ½ x ½-inch, that accepts ½-inch sockets. And high RPM help drive nuts or bolts faster, while IPM kick in harder as the resistance increases. Impacts per minute (IPM) increase as revolutions per minute (RPM) increase. Think of amp hours like the volume of a gas tank-a bigger number equals more gas. Generally, 18-volt tools with advanced features and capabilities make them more versatile and easier to use.Īmp hours (Ah) equals the number of amps that the battery will discharge, continuously, for an hour. ![]() Tools with 18 and 20 volts have less difference between them. This makes them good for smaller jobs, working overhead, or getting into tight spaces. With smaller batteries, 12-volt impact wrenches are more compact. Batteries: Volts and Amp Hours (Ah)Īll things being equal, higher voltage will give you more power-but there are cases for lower voltage. As a result, the twisting motion-known as reactionary torque-that you feel when using an electric drill is virtually eliminated. Fortunately, impact wrenches are extremely comfortable to use because the concussive blows smoothly transfer most of that high-energy torque directly to the fastener, not to your hand, wrist, or arm. However, all that brute strength isn’t very useful if you can’t control the tool. By comparison, cordless impact wrenches can easily produce torque outputs of over 250 foot-pounds, which is more than enough muscle to power-drive the fattest lags and bust loose rusty, corroded nuts. For example, most cordless drill/drivers produce about 50 foot-pounds of torque, and the average impact driver delivers about 125 foot-pounds. It employs both rotational force (torque) and short-burst concussive blows (impacts) to deliver an unparalleled amount of power. Unlike cordless drill/drivers and impact drivers, which excel at drilling holes and driving screws, the impact wrench is specially designed for tightening and loosening various hex-head bolts, nuts, and lag screws. ![]() But for more-production-oriented work, such as putting down decking or building a garden shed, they make a noticeable difference.What You Need to Know About Impact Wrenches How They Work For around-the-house tasks, the added speed and power are often unnecessary. The well-positioned LED can also be switched on independently of the drill, a unique feature that makes it a rudimentary flashlight (which could come in handy in nearly any crawl space). Compared with our 12-volt pick, this larger drill completes tougher jobs much faster, doing the same work in less than half the time, with a battery that lasts longer. This is a larger, 20-volt drill, but it shares all of the most important characteristics of the smaller, 12-volt DeWalt: It’s very powerful and extremely comfortable to hold and use, and the little convenience features, such as the belt hook and the case, are spot-on. If you take on projects that have you drilling lots of holes and sinking long screws, we recommend stepping up to the DeWalt DCD791D2 20V Max XR Li-Ion Brushless Compact Drill/Driver Kit. The DCD701F2 also comes with a nice belt hook, and the battery gauge is located on each battery rather than on the tool, so you can check batteries without having to insert them into the drill. And the LED is positioned so that it illuminates the drill front better than most. The battery is designed so that the drill can stand upright when not in use (other drills, like the runner-up Bosch, need to be placed on their side). The molded handle seems to account for every curve and bulge of the hand, making this drill the most comfortable we’ve ever held. The DeWalt drill’s power is on a par with that of some other models we looked at, but it particularly excels in ergonomics and convenience features. These results show the drill can handle just about anything within the four walls of a home, and even the occasional foray into more aggressive work, like a small decking repair. In our tests, it bored 30 1-inch holes through a 2-by-10 on a single battery charge. The DeWalt DCD701F2 Xtreme 12-volt drill combines power, comfort, and convenience in a way that none of the other tested drills do. ![]()
