Impact wrenches are handheld power tools that are commonly used for tightening or loosening bolts and lug nuts. A more powerful alternative to other types of wrenches, the best impact wrenches have extremely high rotational torque that allows you to loosen stubborn bolts, nuts, and fasteners that have rusted or frozen in place, and drive large coach screws into the timber.
We all know about bolts or nuts that won’t loosen despite our best efforts. Seasoned workers know that when all other tools fail, an impact wrench will probably get the job done.
The ideal solution for tightly wound lug nuts or stripped screws, an impact wrench provides the grip and force needed to loosen even the most stubborn fasteners.
Impact wrenches have electric or air-driven motors that produce powerful twisting motions, in short, intense bursts. These bursts are delivered once every few seconds, eventually loosening even the tightest nuts and bolts.
Impact wrenches are useful for almost anyone, from home builders and carpenters to heavy machinists to automotive specialists. Builders, DIYers, and car owners will especially find these tools useful. Without an impact wrench, you are much more likely to strip a screw or square out a bolt head by hand.
Cordless impact wrenches are especially useful to have around, especially when working in tight spots and corners–which is pretty much always the case when working on a car engine or chassis.
Without an impact wrench, you may have to cut through the bolt or surrounding metal, which is often a more expensive and difficult option.
Don’t confuse impact wrenches with impact drivers. While impact wrenches are used to loosen or tighten bolts nuts, impact drivers are used for driving screws into different materials. Sometimes you can use an impact driver with a socket set attachment for small bolts, but the available power is not even close to an impact wrench when you need to remove and drive large coach screws and bolts.
Reasons to buy a cordless impact wrench
The best cordless impact wrenches are portable, powerful, and surprisingly versatile. Whether you are a builder, a mechanic, or a DIYer, you will likely find many uses for an impact wrench. They are quite handy to have around and can easily be stowed away in your tool bag or the trunk of your car.
Here are some reasons why you should consider buying a cordless impact wrench:
Things to look out for a cordless impact wrench
The tools durability.
Impact wrenches typically undergo tremendous strain and pressure, so you will want one that will hold up to heavy-duty work. The components should fit snugly together without rattling or shaking, and there shouldn’t be an excessive vibration during operation.
And if you will be working with cars a lot, look for a wrench that has a nylon body that can withstand repeated exposure to automotive fluids.
The shape and design.
Loosening bolts often require you to work in tight or confined spaces, with very little room to maneuver.
Consider looking into impact wrenches with small diameter heads and right-angle drives that allow you to work in hard-to-reach spots such as engine compartments. Extended paddle switches also let you operate the wrench from different grip points.
Impact size compadablity.
Bigger wrenches allow you to work with bigger bolts and generally provide more torque as well. However, you will want to go for a wrench that is small enough to be easily manageable and isn’t too bulky to carry around.
The best cordless impact wrenches strike a good balance between power and portability.
The rated and observed power (Torque)
The power of an impact wrench is determined by “torque”, which refers to the tool’s twisting force. This is measured in feet-pound (ft-lb), which refers to the amount of force necessary to move a one-pound weight a distance of one foot around an axis at a one-foot radius.
The best impact wrenches for changing tires can have as much as 1,295 ft-lb of torque. Most models intended for less demanding building and metalwork may have from 500 to 700 ft.-lb. of torque.
Max speed (IPM and RPM)
Impact wrenches are also rated according to impact per minute (IPM) and revolutions per minute (RPM). IPM refers to the number of blows the tool delivers to the bolt to tighten or loosen it. RPM refers to the number of turns the driver makes per minute.
Impact wrenches used for demanding applications may be capable of 1,200 to 1,400 IPM. Most have a range of settings that allow you to adjust the IPM according to the demands of the job.
Its Jobsite appearance
How your impact wrench looks may or may not be an issue depending on your preferences and what other tools you have in your arsenal. I have to admit that a color-coordinated set of tools is nice to have, and tends to give your workshop a more professional look.
An impact wrench in a distinctive color and design also makes it easier to differentiate from an impact driver or similar-looking power tools.
The expected price for power.
Like all power tools, the best impact wrenches can cost a considerable amount of money. But this is something you won’t want to skimp on given the heavy-duty demands placed on these tools.
If you are dead-set on owning an impact wrench and you know that you will be using it a lot, it makes more sense to pay for a reliable model from a reputable manufacturer than to settle for a budget model.
The tools warranty.
A warranty will cover you from damage caused by poor workmanship and substandard parts.
Although you can generally count on models from reputable manufacturers to provide excellent performance, a warranty will still go a long way in easing any concerns you may have about the reliability of a particular impact wrench
Cordless vs. Corded: What should you get?
Choosing between a cordless and corded wrench is often a pretty straightforward decision. The choice often comes down to whether you prioritize power and runtime over portability and convenience.
That being said, many cordless models offer comparable power to the best impact wrenches. A good cordless impact wrench should let you loosen bolts and tighten nuts just as effectively as any corded model.
And with a spare set of batteries, you can get quite a lot of work done before you have to hunt for a power outlet.
Here are the relative advantages of cordless impact wrenches:
