An air impact wrench, also known as a pneumatic impact wrench, is a tool that uses air pressure with the help of an air compressor and air hose to create a rotational force. This force is used to tighten or loosen bolts and nuts. An air impact wrench can be very helpful in automotive repair, construction, and other industrial applications.
However, finding an appropriate air impact wrench in the market with more features and less cost is an incredibly exhilarating experience. This situation becomes more problematic when you are buying a mechanical item like an air impact wrench, and you don’t know which features are more likely to be considered before buying.
Chances are that you will end up buying an expensive wrench that will not only going to charge a lot but will also end up proving itself a purchase in vain. Therefore, looking for a cheap air impact wrench is a good choice. But what if you can get a list of the best air impact wrench under $100. Isn’t it an amazing and exciting thing?
Well, for DIY users, professional mechanics, and other workers, this list won’t make much of a dent in their wallets. Therefore, if you are one of them, make sure to get your hand on this list. Let’s check out some of the best pneumatic wrenches that you can purchase for under 100 bucks.
Shopping Tips – Best Air Impact Wrench under $100 and $50
Before buying a tool or a device, there are certain factors about that particular tool that you should look at before, purchasing. If you have bought a wrench before, you know how many factors or features vary from wrench to wrench.
But, if you haven’t bought one before, then you will need to consider these features before buying a new wrench. Therefore, I am going to discuss some features of a wrench here, so check them out before you purchase:
Torque Value of the Wrench: Air impact wrenches are often required for removing or driving large, rusty, or heavy lugs and bolts. Therefore, they should have a high value of maximum torque. Otherwise, your job will become difficult and you will have to buy another powerful tool for your job.
Furthermore, if a wrench has high torque, then it will probably have high power and flexibility for the job.
However, impact wrenches with less torque also work well for many tasks. But still, certain circumstances require wrenches with high torque.
Hence, before you purchase a wrench, make sure that you choose the wrench with the right value of torque according to your work. Among the above wrenches that I reviewed before, the TZTOOL 1/2″ Diesel air impact wrench offers the maximum torque.
Speed Settings of the Wrench: Impact wrenches with air-powered technology usually have more than 2 or 3 built-in speed settings in them. This feature is quite feasible when you are doing multiple jobs at a time. It provides you with the opportunity to perform multiple tasks.
Furthermore, different types of nuts or screws require different speeds and pressure. Hence, possessing a wrench that has multiple speed settings is just like getting icing on a cake.
Regarding wrenches, there are two kinds of speeds, i.e., heap speed and free speed (also known as impacts per minute). For better performance, free speed should be high. Therefore, selecting an impact wrench with multiple speed settings and an easy speed module is a good idea.
Rather than, choosing an expensive wrench with complex speed customization. Astro pneumatic tool 1822 ONYX 3/8″ nano impact wrench comprises up to 6-speed settings for forward and reverses functioning.
The size of the tool: Impact wrenches are mechanical tools that are specifically designed for use in tight spaces that other mechanical tools cannot reach. Therefore, you should select only the wrench that is small in size.
Otherwise, there is no use in buying a wrench that is the same size as that of another tool. For instance, if you are purchasing an impact wrench that is the same size as an impact driver, then your purchase is going to be in vain.
However, when we choose a small-sized tool, we usually get to know that, along with size, some other features also get shorter just because of the small size. Therefore, first, you have to visualize and analyze all the features of the tool along with its size. Then, you can make your purchase.
One of the smallest wrenches under $100 is the ACDelco ANI308 heavy-duty 3/8″ 150 ft-lbs free speed pneumatic impact wrench.
Weight: Mechanical tools are usually handheld tools. Working with them requires high control and strength, especially when you are handling a tool that offers a high value of torque and power.
Therefore, weight should be an important factor that you should consider before buying a wrench. This is because if you are going to work for long hours, then you will probably be holding the wrench for a continuous duration. Imagine yourself, after hours of this work.
You won’t probably want your hands to get fatigued. Therefore, choose a lightweight and handy wrench composed of light materials to make your working experience comfortable and enhance the efficiency of the tool. The ACDelco ANI308 heavy-duty 3/8″ 150 ft-lbs free-speed pneumatic impact wrench is exceptionally light.
Durability: The durability of an impact wrench is highly significant. After buying expensive wrenches, people often find out that they are not durable, regardless of other high-quality features in them. Therefore, you should buy a wrench that combines good quality materials and has a high warranty.
You can purchase a wrench that has a good, thick casing, or one that is used for heavy-duty jobs. This will help you get a good quality wrench. Furthermore, the construction of a tool also matters, so choose the one with the best build.
