Before you have chosen the right one make sure it has enough gripping materials. Most of the wrenches have a grip on the handle. if you can manage something that has grips all over the body, that will be a nice option. Rubber grips all over the body stabilize the machine at a significant amount.
Socket and anvil compatibility
We have only talked about half inches and 3/8 inches. These will be the contact points where you have to install the extra heads on. Make sure what types of heads are available in your area and choose the anvil size.
If you already own a bunch of heads, get the models right and choose the one that will match up with the sockets.
Get to know where you will have to reach to get your jobs done. If it is under cars, you will require the smallest compact ones. If the job is daunting and needs more power, you should not compromise the budget for the battery and motor power.

modern tools are now compact and yet powerful enough. Avoid the brushed motors that will raise issues in the future.
The power in a compact setup
The power and the push of the motor depending on what is the technology and battery power. The more wattage the battery can provide, the harder the impact wrench is going to hit.
Try not to use the maximum torque on your compact size impact wrench. When you start getting through a rusty nut, make sure that the power of the impact nut is set to low. Gradually raise up to power. This way you can avoid damaging the compact gears.
Don’t leave the wrench unused for years
The normal instinct of a battery is if it is left unused or uncharged, it will decay off the lifetime. When you are not working with your impact wrench, try not to leave it out of your reach.
Take it out of your toolbox once a week and run it until it discharges fully. This cycle will ensure that the battery cycle is normal. Charge it up and leave it for the next working session or a month before the practice runs.
The correct voltage and ampere should be considered
Die to the advancement of technology, you can now charge the batteries faster. The main facts of charging power are wattage. The more the wattage, the faster the battery is going to charge. With fast-charge technology, you can easily fill-up a 4Ah battery within two hours.

Lubrication is compulsory
After almost every month, it will be a duty to get everything running smoothly. If you find any issues, that might be unwanted dirt of rust. A tiny bit of lubricant will do the job just right. Use good grade lubricants which will both protect and keep the workflow smooth.
Uses and Applications of Impact Wrenches
Breaking nut corrosion and rust
The main enemy of any metal is the corrosion and deformation of the metal. In the cramped areas like in the contact points of nuts and bolts, you will obviously find a certain amount of rust or corrosion. Even stainless steels have those. If you are servicing your exhaust mechanism or the radiators, the nuts will be very tough and rough to use your normal wrench.
Several torque impacts are only able to break the rust and get out the nut you want to lose. Nuts in the wheel and inside the hood also show this kind of issue where a cordless impact wrench is the only necessary thing.
A compact yet powerful tool to reach the corners
Where your ratchet wrench hardly reaches to loosen the nuts, there is always a possibility that you might not be able to turn it because of having a shortage of space.
Impact wrenches do not need a lot of space to turn. This is why you should have an impact wrench in your toolbox.
Fast operation on the go
