What’s an electric impact wrench? No matter whether you call it an impact wrench, air wrench, rattle gun or even a torque gun, it’s the same piece of power tool excellence that’s used to obtain difficult jobs completed real fast. The electric impact wrench is obtainable in different sizes, from ¼ inch through ½ inch and 3/8 inches right up to the 1 inch impact wrench, the 1/4 and also the 3/8 impact wrenches. The impact wrench also comes in different varieties, be it air powered or electrical. The primary arena of use for the rattle gun is principally within the automotive manufacturing and servicing industries, where the electric impact wrench is used to insert the and tighten lug nuts when putting tires in place. It truly is also used within the opposite capacity when loosening stubborn nuts and removing wheels. Apart from car industry, it has varied applications at the construction web site, where structural steel frameworks are assembled and utilizing the electric impact wrench.
To make sure your air compressor will work, you need to know the “air consumption” of the wrench (this will be measured in CFM, or cubic feet per minute). So long as your compressor can provide air at 90 psi (the minimum pressure required for proper use of your impact wrench) faster than the wrench will consume that air, your air compressor will be good. Any less, and you very quickly lose torque as your impact wrench uses up air pressure faster than your compressor supplies it. Another important thing to determine is what size drive your impact wrench should be. A lot of people immediately think that bigger is better, but that’s not necessarily the case. You really don’t need a 1″ impact wrench to loosen a 10mm bolt! And you definitely don’t want to try to loosen a 2″ bolt with a 3/8″ wrench. The best thing to do is to figure out what sized nuts & bolts you’ll be using your impact wrench on most frequently. Then find the impact sockets in that size, see what size drive they’re available in, and get the drive size that will work best with the size of sockets you’ll be using.
A pneumatic impact wrench has several competitors in the form of different drive mechanisms. Hydraulic impact wrenches are used in some industrial applications where pressured hydraulics are available, but electric impact wrenches are more popular among home users. It is even possible to get cordless electric variants, although these are typically down on power compared to their more heavy-duty brethren. The type chosen will depend on the context and circumstances; a hobbyist who needs a portable powered wrench will likely prefer a cordless electric version, while more serious professional use will likely require the more powerful pneumatic option.
A pneumatic impact wrench is a great choice for removing difficult nuts or bolts. There are some alternatives, such as the cordless electric variant, which may work better for some people, but for sheer power and performance, it is hard to beat compressed air. Look to the torque and weight of the air gun to determine its suitability. There is no sense in buying a wrench with either much less or vastly greater torque than you require, and a heavy model will cause you some discomfort when used for long periods.
While I really enjoy cordless impact wrenches because of their surprising power and portability, a lot of times it’s not enough. I don’t think I’ll ever take the air powered gun out of my box because of its superior power and durability. Actually I wouldn’t take either out of my box because they both have their places in and out of the shop. It really just comes down to knowing what you will need your impact wrench for. The portable cordless is great for small to medium torque projects while the compressor powered air impact is good for low, medium, and high ranges of torque.
