In any home DIYs or auto repair works especially changing tires, loosening and fastening nuts and bolts can be a tiring job, especially if its repeating process. Even more so, loosening a rusted bolt can be harder. Using handheld ratchet wrenches is ok if its one time or very few nuts. For anything else involving few hours of work to a frequent activity, you need an Impact Wrench. They are either Pneumatic or battery operated and deliver huge power in terms of Impacts and Torque to loosen or fasten the bolts and nuts. For a rusted tools, it gives more impact in an instance. The speed at which they rotate to loosen/tighten bolts is unparalleled. Best Impact Wrenches have a balance between Impact and Torque
The pneumatic wrenches use power from air compressors to deliver the impact and the punch while battery operated ones use power from the batteries. There is a similar tool called impact drivers that are predominantly used to drive lug nuts into place. One main difference between Impact driver and Impact Wrench is the driver comes with a Hex shaft to hold the nuts and turn them in while Wrenches come in Square shaft. Drivers are also used to drill holes and screws in. There are few tools that come with both features, hybrid that acts as driver and a wrench.
After hours of research, we have identified the best impact wrenches you can buy for your house and professional purposes. We have also got you the Buying guide that will help you understand what to look for before buying one for yourself.

In Automotive repair works, frequent use of Wrenches is a given. Impact wrenches saves you lot of time and energy when you loosen/tighten lug nuts on the tires.
If the nuts and bolts are frozen or rusted, it is nearly difficult to open them manually. Impact wrenches provide an impact or a force that will loosen them and will also remove them easily for you.
When working on construction projects, lengthy backyard projects, an impact wrench will save lot of time because fastening and loosening lug nuts will be an important part of these jobs.
When working with bigger bolts especially on larger items, impact wrenches are the go to items to fasten and loosen the bolts. They do it with such ease that you don't feel any weary at all.
Two types are there - Brushed and Brushless. Brushed motors have less efficiency then Brushless whereas the latter has more speed and power. They come at bigger price too!
Torque is the power used to turn the nuts and bolts. RPM is revolutions per minute that the motor rotates while IPM is Impact per minute that is the number of impacts exerted on the lugs per minute. Higher the torque, the powerful the wrench is, while more IPM means better for tight, frozen lug.
The wrench drive that connects to the socket which in turn connects to the nuts is important. Available sizes range from 1/4 inch to 1 inch, where larger the drive size, the more powerful it is.
Pneumatic and Battery powered are the two types here. Of course pneumatic wrenches work with great power but needs air compressor to give the power. Battery operated wrenches are easily carried around and gives decent enough power.
If it is a cordless battery operated wrench, you need to look at the "V" and the "Ah" values. Higher the voltage (V), more powerful it is, while higher the "Ah", longer the machine runs before drying out.
Other features like the Grip and Vibration can also be considered. In general, the vibration has been well tuned in most of the cordless wrenches. Sound of the motor can still be an issue.
Milwaukee M18 is the big boy of the cordless impact wrenches. It is powerful and intelligent. With a torque of 1000 ft-lbs and force of 1400 ft-lbs, any tough job is a cakewalk. There are four drive modes with one mode called "Bolt removal mode". At this mode, the speed is automatically reduced once the bolt is broken loose so that they don't fly off at high speed.
Build quality of also very good with rubber finish across the handle to keep vibrations to a minimum. High power means higher battery requirement, but you get two 5 Ah batteries and you should be well off for a whole day tire replacing job.
