Technological advancement has made much easier our lives. However, it has also made the products we are looking for available is so many options that we again, ironically, find it difficult to get what we want.
This is what many first timers go through when looking for what impact wrench to buy.
With so many brands and models of impact wrenches available in the market, making a choice on that one to buy can be a daunting task.
But, with the right information, you can get one that will not only deliver more than your expectation but also serve you for a long time.
Here are the most important considerations:

What Impact Wrench To Buy
Power Source
You can choose between three standard varieties of impact wrenches based on power source.
Many of the impact wrenches used in auto mechanic shops and home are compact air impact wrenches. They can generate a significant amount of torque, making it a great tool for heavier jobs.
Electricity powered models may also produce a lot of torque but less than that provided by air impact wrenches.
This variety of impact guns can be either corded or cordless (battery-powered) each with its advantages and disadvantages.
Weight
Weight may not be a factor in light jobs that take short times to complete.
However, you will need a lightweight model if you are a frequent and heavy user of an impact wrench. When you are fatigued, a massive machine may be harder to control and exhausting to hold.
This may result in a bad outcome and risks to your safety.
Minimum and Maximum Torque
Imagine having to remove a large rusty bolt that has been beaten by environmental elements. Obviously, removing such a bolt will require an appreciable amount of torque.
Each impact wrench model has a maximum torque it allows you to choose the right torque to operate at.
Look for a minimum of 150 feet per pound (1800 inches per pound) and the highest maximum.
Size of the Impact Wrench
We can all agree that the smaller the impact wrench, the better, but there is a very thin line between size and torque.
Small, compact models will allow you to work in tighter spaces, but that means you must be ready to sacrifice a little torque. The best impact wrench to buy is one that tries to achieve a balance between the two.
Torque Adjustment
A power wrench turns the socket as great speeds and in very little time.
This may make it difficult to know when the job is done. Torque adjustment allows you to control the output torque of the wrench. This way you can reduce the risk of over torquing (applying excess torque) or snap a bolt head. Not all impact wrench models have this feature.
No Load Speed
No load speed defines the speed at which the wrench can turn when it has no load on it.
Obviously, higher speed will mean the wrench is capable of fastening or loosening bolts and nuts faster. This more top speed is functional, but it comes with reduced torque, and so you need you need to achieve a balance between these two important features.
Impacts Per Minute (IPM)
The best impact wrench should have high impacts per minute (IPM) rating.
It because the power tool needs a lot when it comes to contact to tighten or loosen a bolt or screw and push it down. Models with high IPM are always costly.
A good way to go around that is to achieve a balance between RPM and IPM.
Socket/drive Size
Another important factor to consider is the socket or drive size. Most commonly, 1/2-inch drives will do the job for most applications.
This is closely followed by 3/8” drives. The latter size will always come in a smaller total package, but it will have less torque than a comparable 1/2-inch socket.
If possible, you should impact wrench models that are compatible with multiple drives.
Ergonomics and Balance
Besides going for a lightweight and compact sized impact wrench, you also need it to offer perfect ergonomics and to be well balanced. Try to look for an impact wrench model that fits perfectly into your hand with comfortable grip material.
The tool must also feel balanced in your hands to reduce fatigue and strain during extensive use.
Impact Wrench Shape
If you are keen, you will notice the two most common shapes of impact wrenches – inline and pistol.
An inline impact wrench may be described as resembling an oversized screwdriver with the anvil or hammer located in front of the grip.
The pistol type is similar to a pistol with the hammer or anvil located above the grip. The type to choose between the two depends on your preferences.
1. What is the right RPM and IPM for impact wrench?
Each impact wrench brand or model has its RPM and IPM ratings. Try to achieve a balance between these parameters and torque.
2. What is the difference between Inline and Pistol impact wrenches?
The difference is in the shape of these tools. Think of inline models as resembling large screwdrivers and pistol models to resemble pistols.
3. How much does an impact wrench cost?
The cost of impact wrenches depends on many factors that each plays a role. Those models with a right combination of features and specifications will be an absolute value higher than the usual quality brands.
4. Where can I buy an impact wrench?
You have two options – you can buy one from a local hardware or automotive store close to you or purchase one online from a reputable online retailer such as Amazon.
5. Is it safe to buy an impact wrench online?
Of course, the internet offers an incredibly convenient way to purchase any product. All you necessary to do is follow the required steps, make payment and expect your wrench to be delivered right at your doorstep.
Last Word
In comparison to other power tools we always use at home, impact wrenches are quite specialized.
I believe you are now well informed to make a smart choice when it comes to what impact wrench to buy. By taking your time to research, you will not only find the best-suited tool for your needs but also ensure you make a smart investment.
