Are you having a hard time choosing which is a better impact wrench between 3/8 and 1/2 for you? Well, I am here with a comparison between the two to help you choose a better impact wrench. Although they are used for the same purpose, they are still very different from each other in many aspects.
As we know, an impact wrench is used for tightening and loosening the bolts and lug nuts (which are used to secure a wheel on a vehicle). An impact wrench produces torque in rotational motion after a person applies sudden force. It can be either corded or cordless.
The bolts and lug nuts of different vehicles are different in size and therefore need different kinds of impact wrenches. These impact wrenches have different power, sizes, durability, etc which I will be talking about in this article. I will be differentiating between 3/8 and 1/2 impact wrench making it easier for you to find the suitable one. Let’s explore the differences between the two.
Comparison Between 3/8 And 1/2 Inch Impact Wrench
Before starting the comparison, it is essential to know what does 3/8 and 1/2 mean? The numbers 3/8 and 1/2 indicate the diameter of the wrench. It indicates the size of the driver present at the front of the impact wrench.
3/8 Impact Wrench
A 3/8 inch impact wrench is very small in size as compared to other impact wrenches. Moreover, it is lighter in weight and is not bulky like other wrenches. Because of being light in weight, it produces less pressure which is used in those spaces where a small amount of pressure can tighten or loosen the bolts or nuts. This impact wrench is very suitable for use in tighter spots.
One can use a 3/8 inch impact wrench on places where he has to apply torque on only one point. This wrench has a weaker motor than the one used in a 1/2 inch impact wrench. The 3/8 inch impact wrench is used in removing or installing those nuts and bolts which require torque less than 90 ft/lbs.
1/2 Impact Wrench
A 1/2 inch impact wrench is heavier in weight. It is used for those nuts and bolts that have a higher diameter. This wrench can tighten or loosen lug nuts, rusted nuts, and bolts. 1/2 impact wrench consists of a powerful motor because high torque is applied to the nuts and bolts. It is present in a pistol grip as well as an in-line grip design.
One of the main advantages of having a 1/2 impact wrench is that you don’t have to worry about the wrench having insufficient power. The reason behind this is that a high-power wrench avoids the risk of the tool not working in some spaces because of the lack of power.
Differences in Size
As stated above, the 3/8 impact wrench is smaller in size and lighter in weight. Because of its weight and size, a 3/8 inch impact wrench is very easy to handle. This impact wrench is more portable as compared to a 1/2 impact wrench. It can be used in a normal routine at home for the automotive.
1/2 inch impact wrench is larger in size and bulkier. This wrench is not as portable as 3/8 because of being heavier in weight. It is not easy to work with this wrench in a normal routine. This wrench is usually used for heavy automobiles that need higher torque to tighten or loosen their nuts and bolts.
Differences in Design
Many different companies manufacture impact wrenches but the designs are very slightly different from each other. The main common thing in the design of both wrenches is that they have a shape of a gun with a rubber handle. This rubber handle helps to provide a good grip and makes it easier for a person to hold the wrench for a long time.
Moreover, these wrenches consist of a trigger similar to a gun which on pressing starts working and on releasing stops working. Both the wrenches contain a LED light that focuses on the spots where the work is being done. The only thing that differs in the design of these wrenches is their impact wrench driver which is different in size for different impact wrenches. Besides that almost all of the wrenches have the same design having a gun shape look.
Differences in Power
1/2 impact wrench is more powerful than 3/8. The reason behind this is that a 1/2-inch impact wrench is made up of a high-power motor. While, on the other hand, a 3/8 inch impact wrench is made up of a weak motor. High power motor produces high power torque while a weak power motor produces less torque to some extent.
In a 1/2 inch impact wrench, one can apply the torque from 20 ft/lbs up to 150 ft/lbs. A 3/8 inch impact wrench can apply the torque from 10 ft/lbs up to 90 ft/lbs only. Using a high-power impact wrench can make your work easier. That is why a 1/2 inch impact wrench is more suitable than a 3/8 inch impact wrench in terms of power.
Differences in Functioning
Coming towards the functioning, both of the impact wrenches are slightly different. If one wants accuracy then a 3/8 inch impact wrench is suitable for use. While, on the other hand, if one wants a high-power impact wrench and minimum risks, then a 1/2-inch impact wrench is suitable.
A 3/8 inch impact wrench has low power but assures the accuracy of the work. It mostly focuses on the tighter points. A 1/2 inch impact wrench provides high power and minimizes the risks of nuts and bolts not being tightened or loosened because of the lack of power. Because of this reason, a 1/2 inch impact wrench is one of the most commonly used impact wrenches.
Differences in Precision
Being lightweight and having low power makes a 3/8 inch impact wrench more precise and accurate as compared to a 1/2 inch impact wrench. A 3/8 inch impact wrench is smaller as compared to a 1/2 inch impact wrench, so it assures more accuracy by focusing on one tighter spot.
A 1/2-inch impact wrench is less precise because it does not focus on only one point. Another reason behind the less precision of 1/2 inch impact wrench is that because of its heavy weight, it can not provide accuracy. A 1/2 inch impact wrench is best for removing bigger nuts and bolts. So a 3/8 inch impact wrench wins the race in case of providing more precision than power.
Differences in Use
As we know that 3/8 inch impact wrench is more suitable for tighter spots. This impact wrench can be used at homes for automobiles, DIYs, and many other purposes. It is more accurate and precise because it focuses on only one point. A 3/8 inch impact wrench can be used for some appliances where a high-power wrench is not required.
1/2 inch impact wrench is most often used for heavier machines. Some nuts and bolts require a high-power wrench with a high-power torque of up to 150 ft/lbs. A 1/2-inch wrench is more commonly used because it is easier to remove lug nuts and rusted bolts from this wrench because of its high power.

Which Impact Wrench Should One Use?
It is hard to choose between a 3/8 and 1/2-inch impact wrench. Both impact wrenches are equally important. A 1/2-inch impact wrench is important for use in heavy vehicles and roomy places. The 3/8-inch impact wrench is portable and handy.
Although a 3/8 inch impact wrench has low power and can work up to a certain limit of torque, It can help a person automotive in their daily routine for those nuts and bolts that do not require high power torque. Being lightweight makes them easy to use and travel-friendly. In my opinion, a person should have both impact wrenches because both of them can be used in different places.
Everyone should have impact wrenches at home for the tightening and loosening of the nuts and bolts. One should have both of these impact wrenches. You can use a 3/8-inch impact wrench for the things which require low power and a 1/2-inch impact wrench for the things that require high-power torque for their removal or installation.
Selecting one between ⅜ inches vs ½ inches impact wrench power tools is a tough decision to make. If I compare both tools in their power then ½ inches impact wrench is much better and faster than ⅜ inches impact wrench. ½ impact wrench provides more torque, which helps to level the pipes, nuts, and bolts accordingly. If I talk about weight then ⅜ impact wrench is lighter in weight and handier as compared to ½ impact wrench.
The power battery of ½ inches impact wrench provides faster fitting and loosening of nuts and bolts. If I talk about the function then both wrenches are best to use but ½ impact wrench is more powerful, bulkier, and has a bigger battery for heavy-duty work. I tested this tool and I found that it is better at removing, and tightening nuts and bolts. The design of both the wrenches is quite amazing and ergonomic with rubber handles that provide soft gripping.
A 3/8-inch impact wrench is portable and easier to use for a long time because of its size and weight. A 1/2-inch impact wrench is a little hard to use for a long time because one needs to have a strong hand to use this wrench for a long time.
I hope that this guide was helpful to you.
