(Last Updated On: July 4, 2018 )

Many people need an impact wrench in their toolbox, but only a few have a durable one. That’s a fact many people only realize after getting a new impact wrench and use it for some time. When it comes to buying impact wrenches, there are lots of variables to consider. These variables come in forms like torque, IPM, BPM, RPM, and lots of other acronyms. While these numbers may sound more confusing to a novice, we won’t confuse you with them. On this review are ten of the best impact wrenches from different manufacturers. But just before we write on best cordless impact wrench for automotive, we are going to educate you on factors that make them the best. Also, we are going to give you an insight into how these products made our list. Therefore, you are going to understand what we did behind the scenes by reading this review. Furthermore, we are going to reveal to you some factors to consider before buying the best cordless impact wrench for automotive. The products in this review have gained traction in several marketplaces (offline and online). Therefore by reading this review, you will save some time and money you would’ve spent on the wrong wrench.

How we came up with the best cordless impact wrench for automotive

Getting the best cordless impact wrench for automotive is quite dicey for lots of people, but for us, it is not. In our search for the best cordless impact wrench for automotive, there are some factors we considered. One of which is the Torque generated by the wrench. Yes, torque matters a lot if you want to have an easy work done. Also, the ability to control the amount of torque generated also matters. Since every application needs a certain amount of force on it, having one with just one torque setting is not ideal. Also, adjusting your wrench to the minimum required torque saves some battery life for more work. Other than torque, the battery life also matters (since we are considering cordless impact wrench). More battery life means more work time. The shapes and socket size is another factor we considered before writing this review. Nevertheless, the importance of this factor depends more on the user. Some people prefer to go with an inline design instead of pistol grip, but that depends on what they are comfortable with. We also considered durability when searching for the best cordless wrenches. We did this by considering the changes in design and the material used in making the wrenches. The materials used in making these wrenches helps in preventing damage due to drops or heat. Price is another factor we considered though most products are in the same price range. The last factor we considered is the perception of previous users of the product. The more positive the user perception is, the better impact it has on our ranking.

Things to consider before buying a cordless impact wrench for automotive

Torque:

The amount of torque generated by the wrench is a measurement of the power of the wrench. The more torque it has, the faster the motor rotates, and the faster it screws up nuts.

Torque control settings: 

If the kind of work you do involves a specific amount of torque, having a torque-adjustable wrench is important. Another reason why you should consider torque setting is the battery life. If you’re considering having long working time with a battery powered wrench, you should get one with variable torque setting.

Durability: 

Before buying a wrench, you should consider the kind of material it is made of. Sometimes when working with a wrench, accidental drops may happen. If you don’t have a tough wrench, there may be damages due to accidental drops. These damages may add to your maintenance costs in the long run. Therefore, it pays off to get a wrench with great build quality.

Comfort:

The kind of handle a wrench can determine the level of comfort you’ll get during its operation. Also, the anti-vibration mechanisms on the wrench determine how comfortable it is to use it. As a result, you should be considering these factors before getting the next wrench for your toolkit. Getting a wrench with exactly the right level of torque to perform the job can improve comfort. However, getting one with an adjustable torque level is a great bargain and is more useful for different tasks.

    How to use a cordless impact wrench

    Just had an impact wrench and you can’t figure out when to use an impact driver and how to use an impact wrench? Well, this section will address those issues. In addition, you are going to understand how an impact wrench works. Also in this section, we are going to throw some light on impact driver vs. impact wrench. So let’s start impact driver vs. impact wrench.

    An impact wrench is used to tighten and loosen nuts and bolts by reducing the effort required by the user. While an impact driver/drill is made for drilling holes into a surface and drive screws into it. An impact wrench is used to drive screws into already threaded holes. It does that faster than any other tool you would have used for such purposes. On the other hand, an impact driver is only used when you what to drive holes into thick surfaces. Such surfaces could be metals, concrete, wood, etc. The impact driver uses rotation and blows to drive screws into dense surfaces.

    Impact drivers normally have great force when compared to impact wrenches. Of course, it has to be so because they do different tasks and that of the driver is much harder. Therefore you should consider getting an impact driver if the project involves driving a ton of screws. Impact drivers aid in the building of decks, installing tile backer board and screwing plywood subfloors. You should only use a cordless driver if your project involves loosening and tightening of nuts and bolts. 

    An impact wrench works by applying a force which causes rotation (alias torque) in short bursts (alias impacts). This force is caused by a rotating motor inside the casing. The rotating motor may be powered by compressed air, electricity from batteries or a power outlet. The ones powered by air or batteries are known as a cordless impact wrench. While the ones powered by electricity from a mains outlet are referred to as corded impact wrench.

    So how can you use an impact wrench? Well, you should know that there are different types of wrenches and each has the own specific system of operation. So let’s talk about how to use an air impact wrench.

    • First and foremost you should assemble the air impact gun by following the instructions that come with it. You should attach the hose to the pressure unit first before attaching the other end to the wrench. By so doing you are free of using the hose at any time through the use of quick release clip.
    • Test your set up: You should check your set up for the correct pressure levels of your air pressure wrench. Set your PSI level to something between 90 and 100. Also, check the hose line for any bends or twists and straighten it if you found any. Check for the direction of the air impact wrench by tapping the trigger lightly and notice how it turns.
    • Next, adjust the speed to the correct speed setting by making use of the dial or switch. Once you are satisfied with the level of speed and torque, you can attach the right sockets size to the bit at the tip of the wrench. Fit in the socket bit onto the nut of the wheel and press the trigger on the wrench. When this is done correctly, the nut should easily loosen or tighten as you want it to.

    That’s it for air powered wrenches. If you have an electric wrench, then you should follow these simple steps

    Step 1:

    Look for the appropriate socket: Changing the socket is the first and most important step to take when you’re using an electric wrench. If you’ve connected the wrench to the mains power supply, you will have to disconnect it before changing sockets. After choosing the appropriate socket, keep it tight onto the square drive of the torque gun.

    Step 2:

    Hold the wrench firmly in your hands, and pull the rocker switch. Next, put the socket at the tip of the fastener. Leave if for some time and allow the wrench to build more torque as you retain the wrench on the nut. The wrench will loosen the nut gradually.

    Step:3

    Dislodging the nut: Change the wrench motion mode to the reverse mode. Next hold the wrench firmly with both hands in order to be more stable as you work. Hold the trigger to the greatest extent and place the socket on the nut head. Keep your fingers on the trigger while the wrench is still on the socket head. The torque action will loosen the nut. After the nut is dislodged, release the trigger. Continued hold on the trigger after dislodging the nut may damage it. You can repeat these steps if you have several nuts in your work-piece.

    Step 4:

    Tightening of nuts: Place the nuts into the threaded hole using your hands (make sure it isn’t cross threaded). Choose the appropriate socket to be used on the wrench. Place the socket firmly onto the wrench.  Next, adjust the switch to the forward mode. Place the socket over the nut head and hold the switch firmly and pull the trigger. Carefully regulate the spindle speed by controlling your fingers on the trigger. Keep doing this until the nut is nipped in the hole. Do not tighten the nut yet until you’ve place other nuts on the workpiece in a similar manner.

    Step 5

    Turning off the machine: Once you are done with your work make sure to put off the machine. Unplug it from the power socket (if you are using a corded wrench). Remove the sockets and keep in a cool, dry place. Make sure your pets and children never get to where these tools are. It may injure them if not handled properly.
