This guide covers what’s needed to understand cordless impact wrenches and make the very best impact wrench selection for your situation and budget.
The information in this guide comes from both research and experience with impact wrenches and other power tools in the home and commercial settings. I have created a select field of cordless impact wrenches that will work for a wide variety of applications and budgets.
How to Choose an Impact Wrench
The most valuable use for any impact wrench is the loosening of stubborn nuts on cars, tractors, heavy equipment or other machinery. You might think that a battery-powered impact wrench might fail in busting loose a rusty, stuck lug nut almost two inches in diameter, but the best cordless impact wrench can do it. Read each cordless impact wrench review carefully to find the best impact wrench for the money for your particular tasks.

Review
If you have ever tried busting loose pulley nuts, you know how tight they can be. The W7150, the highest torque impact wrench in its class, will spin them out like soft butter.
The W7150-K2’s power is equivalent to many air impact wrenches without the air hose hassle.
Some buyers are fooled by the light weight of this top-rated impact wrench, but it is built to last both inside and out.

Review
If you work on heavy equipment such as bulldozers, backhoes, and scrapers, this is the best ½-inch impact wrench around. For the rest of us, it is probably overkill, but if it cannot remove a decades-old, solidly-rusted 1.5-inch lug nut then nothing can.
Due to the hefty brushless power plant, the weight and top-heavy design make it unwieldy for casual users.
3. DeWalt DCF880B 20-Volt Li-Ion 1/2″ Impact Wrench Tool Only

- Battery Life: 4.0Ah
- Weight: 5.75 lbs.
- Warranty: 1-year warranty on defects
Review
The extra $40 or so you pay for this upgraded C3 version is money well spent. It spins off rusty lug or chassis nuts in quick order. The Li-Ion 4Ah battery and high torque mean hours saved for car or tractor repairs. It is not quite up to commercial tasks, but for the price and power, it is ideal for home shops.
7. Makita XWT02M LXT 1/2″ Li-Ion Brushless Cordless Impact Wrench
This Makita 18V LXT ½” impact wrench features 3-speed selection, 210 foot-pounds of torque and long run times. Its compact size, lightweight, and speed/impact ranges provide fine control for any fabrication, installation or automotive work. It is powered by fast-recharge, 4Ah Li-Ion batteries.

Review
With 35 percent longer run times, 3-speeds plus reverse, separately-switched lighting, fuel gauge, etc., it has all the features to get work done efficiently. Makita has even added dust/moisture protection to the tool housing. The only complaint from buyers is the fan noise from the charger, but the cooling it provides speeds up recharges.
8. Industrial Brand CDI Torque 2503MFRPH 1/2-Inch Review
** Editor’s Choice – Torque Wrench for Finishing Touches **
This industrial-grade manual torque wrench is for heavy-duty jobs requiring high precision. The dual-direction, twin-scale shaft measures 30 to 250 foot-pounds, or Newton-meters if you prefer, of torque. The included test certificate illustrates three forward and three reverse factory test measurements, which report the actual deviation from true torque. Usually, these are less than one percent off. It is a superb measurement tool to back up non-existent or less-than-perfect calibrations on cordless impact wrenches.
Pros:
- Heavy-duty steel construction
- Made in the U.S.A.
Cons:
- Calibration settings need higher contrast
- Drive size: ½-inch
- Length: 24 inches
- Torque settings: 30 to 250 foot-pounds
- Calibration: Dual scales, laser-marked
- Accuracy: No greater than 4 percent CW and 6 percent CCW, nominally less than two percent
- Warranty: Lifetime warranty on defects
Review
The strong point of most cordless impact wrenches is in busting stuff loose, not tightening to a specific torque. When tightening critical parts such as head bolts, use a quality, manual torque wrench such as the 2503MFRPH. This one has a wide range, so it is suitable for motor and heavy equipment work. The only gripe from buyers is that under bad light the markings on the shaft are hard to read.
Why Do You Need an Impact Wrench?
If you have ever spent several minutes in an uncomfortable position turning a stubborn nut in 1/16th steps or have been unable to develop sufficient leverage to bust loose a rusted nut, then you already know why you need an impact wrench.
Almost anywhere you use your manual socket wrench, you can use an impact wrench. The only practical limitation is the bulk of the impact gun, which may preclude use in the tightest spaces.
It is not the primary purpose of an impact wrench, but it can double as an impact driver/drill. You may have to use a socket-bit adapter or buy a combo tool such as the Bosch IDH182-02L, which has a dual-ended chuck. Unless you use the dual-torque feature of the Milwaukee 2454-22 impact wrench, you have to control the increased torque when driving or drilling with an impact wrench to avoid damage.
How Does an Impact Wrench Work?
So, what is an impact wrench versus a hammer drill? Hammer drills are fundamentally drills with a pounding action on top. Most of their action is high-speed rotation with relatively low torque. They produce a counter-rotation that must be matched by the operator. Impact wrenches use a different principle to produce higher torque at all rotational speeds. Via a hammer and anvil mechanism, they produce high torque in brief spurts. Each torque spurt may have a force of hundreds of foot-pounds, which even sticky, rusty nuts find difficult to resist. Because the hammer/rotation cycles are extremely short, there is no sustained rotational torsion produced as in drills.
Impact Wrench Applications
The general rule for applying an impact wrench is to use it mostly for taking things off not for putting things on. It is a superb tool for busting loose tight bolt nuts, especially ones that have too much corrosion to break out easily with hand tools.
These include lug nuts, chassis bolts and any other nut that has been exposed to weather. Using an impact wrench in short bursts avoids shearing the bolt until the nut moves freely.
Impact wrenches can be used in combination with sockets or screwdriver adapters for driving fasteners into wood, metal or concrete. Most of the best cordless impact wrenches reviewed here double as impact drivers in this fashion. Like drivers, they can extract partially stripped screws without cam-out.
Impact Wrench vs. Impact Driver
Most impact drivers are smaller, often cordless, tools used for drilling holes or driving screws. As a class, impact wrenches are larger and more powerful. They typically produce significantly higher torque than impact drivers. The largest air-powered impact wrenches produce thousands of foot-pounds of torque. Since most impact wrenches are used in automotive or other mechanical shops, they usually have a square-ended chuck similar to a manual socket wrench in ¼-inch, 3/8-inch or ½-inch sizes.
On the other hand, impact drivers usually have a ¼-inch female hex socket for holding bits. Since they produce lower torque than impact wrenches, they are typically smaller and lighter. This makes them ideal for carrying around job sites, up ladders, in attics, and under the house. Most are compact enough to reach into small spaces.
Making the Decision
Good quality power tools are not so cheap that you can buy a new one every week. Furthermore, they should be thought of as investments that will produce dividends for years to come rather than consumable items. Thus, the decision to select and purchase the right tool for your tasks and your budget should not be taken lightly.
The main thing in making the buying decision is to feel that you have sufficient, quality information on which to base your choice.
The primary purpose of this guide is to provide you exactly that kind of information. After reading through the data and reviews here, you are ready to select a great impact wrench, impact driver or driver-drill that exactly meets your requirements.
