Cordless Impact Wrench Guide For Power Tool Users

One of the first things that usually comes to mind as an ideal power tool is a cordless impact wrench. There are plenty of good reasons why most men would like to own one. It looks great and the torque it brings to bear is amazing, but it's also popular because it actually happens to be very useful for a wide range of applications. Let's take a look at how it's used, and also find out why the battery-operated portable version is such a big hit. Considering the way they work, these wrenches are also known as impactors. Rotational motion generated using electricity, hydraulic power or compressed air is transferred to an output shaft that makes the impact. The high degree of torque that gets applied in this manner in both directions using forward and reverse drives turns screws, bolts and nuts with no additional human effort required. No doubt it covers a vast range of applications, but its most prominent use is for automotive repair. These wrenches also come in handy in factory assembly lines and construction sites where workers use a lot of screws, nuts and bolts. Assembly or construction work as a repetitive function using manual tools is not impossible, but it's extremely hard work and reduces productivity. It's a whole lot easier with power wrenches, since they generate a huge amount of torque and the person holding the tool doesn't have to put in any effort. Even a puny battery-powered half-inch drive can easily roll lug nuts that need 100 pound-feet of torque. It even makes light work of a one-inch bolt that needs to go in or out of a steel beam on a construction site. The most famous application of this tool is by pit crews in car racing events such as Formula One. Racers coming in for a pit stop have to be out again after a few seconds. Refueling is obviously one of the primary tasks, but the pit crew also takes the opportunity to put in fresh tires. Opening wheel nuts and studs and putting them back in within a few seconds would be impossible without power tools. Traditionally, power tool users have preferred their wrenches to be powered by compressed air. But the cordless era has triggered a shift towards electricity. The corded ones hooked up to wall outlets obviously run on AC power. But the battery-powered cordless wrenches typically require DC power with 12V, 18V or 24V output. The buyer has an array of options to choose from, including different styles and sizes available in different makes and models from all the major power tool brands. The small one-fourth inch drives used as automotive wrenches are inline tools which work like screwdrivers. The larger heavy-duty square drives used on construction sites may be 3.5 inches or more, and have pistol grips. The use of a cordless impact wrench is not just about saving time and reducing fatigue so that workers are more productive. It's also better from a health aspect because it minimizes the damage caused to the human body when using such tools. The vibration impact of power wrenches is relatively nothing as compared to the pain of using manual wrenches, screwdrivers and hammers all day long.
