1. Milwaukee 2763-22 M18
This is our number one choice because it provides so much torque. When used on a fastening setting, you get up to 700 pounds per foot, but you can increase that torque up to 1,100 pounds per foot on other settings. It comes with a brushless motor that runs smoothly and won’t overheat and a friction ring for quick socket changes.

2. Milwaukee 2763-20 M18

Another benefit of this product is that it can run for up to twice as long as that same high torque output as other models can, though you will need to purchase a battery to use with it. It also comes with a five-year warranty from Milwaukee.
The ½-inch anvil that it comes with works with its friction ring to make changing bits and sockets easier, though you may find it hard to turn this ring. This model also features a drive control setting for using it as a fastener.

4. DEWALT DWMT70773L
When changing tires and doing other projects at home, this DEWALT model is a good choice, but it won’t meet up with the daily demands of an auto repair shop.

One feature we like about this Kawasaki model is that it comes with a simple trigger that has a forward button on the bottom and a reverse button on the top for fastening and loosening.

8. Campbell Hausfeld TL140200AV

It also has a brushless motor that provides the power that you need without the risk of the motor overheating. The 700 pounds per foot of torque it provides for fastening works just as well as the 1,100 pounds per foot or torque it offers for driving.
A fraction ring makes it easier to change out sockets for future jobs. It also features a drive control setting for faster and more efficient driving.
How to Choose the Perfect One
What is the Maximum Torque Produced?
Even if you just want to change a flat tire without visiting the mechanic, you still need to know how much torque the tool produces. Some manufacturers use a pound per inch rating because this makes the tool sound more powerful, but you can determine the amount per foot based on that rating. For most jobs, you will need a rating of at least 150 pounds per foot, which is around 1,800 pounds per inch.
What Type of Power Does it Use?
Auto repair and mechanic shops use models designed to work with an air compressor, which means that you’ll need an air compressor of your own to use one of these models in your own garage. Many have a power cord that works with an outlet and uses electricity to power the motor. You’ll also find some that you can plug right into an outlet in your car for taking care of repairs while away from home.
Does it Have a Standard Socket Size?
Most of the models that you see designed for home use have a standard socket size of ½ inch, but there are others that have a ¼ inch or 3/8 inch socket size. This tells you the size of the sockets that you can use with it. You may want to look for a model that actually comes with a set of compatible sockets.
Are There Any Included Accessories?
While you shouldn’t base your final decision on any accessories that come with a power tool, those accessories can come in handy when handling some of the jobs around your home. Some companies provide you with a socket set that works with the chuck on the tool. Others may give you a carrying case made from a hard or soft material for storing the tool and accessories.
Does it Perform Other Functions?
When you need to save space and want tools that you can use in multiple ways, you should consider one that you can use in multiple ways. One example is a tool that functions as both an impact driver and wrench. Some models will also work as an impact hammer.
How Many Rotations Does it Make in a Minute?
The rotations per minute than a tool makes is its RPM rating, which many manufacturers refer to as its revolutions per minute rating. Look for one that produces between 1,000 and 2,000 revolutions or more per minute. In general, the faster it spins, the faster you can complete your work.
You should keep in mind that a higher rating may increase the overall weight of the tool and make it harder to hold. Find one that combines a low weight with a high RPM rating.
