What is an Impact Wrench

At first sight, the impact wrench looks like a usual drill. That's true, yet impact wrenches are designed merely for turning bolts, nuts, or anchor bolts. An impact wrench seems to be a weird design, as we have impact drivers that are capable of screwing and unscrewing. Still, an impact wrench has much higher torque than of impact driver. Furthermore, impact wrenches feature nut-busting torque that helps to loosen a strongly tightened or rustbound nut.

Hence, an impact wrench it's a perfect tool for handling bolted connections, for example, metalware assembly or car servicing where torque tools are must-have. So, we will analyse the main aspects to choose an impact wrench right.

If you deal with driving screws apart from bolting, an impact driver will surely be helpful, and we advise to use hearing protectors to secure your ears from motor buzzing.

What Features to Compare

Type

Fist of all, pay attention to the type of an impact wrench. These tools are electric, pneumatic, or hydraulic. Electrical impact wrenches are the most widespread and usable; there are corded and cordless models. Corded tools are lightweight and work longer, while cordless ones are more portable and handy. The corded wrenches are often used at industrial facilities or workshops where workers operate the tools in the same place. The cordless models are generally purchased by handymen as they can be used anywhere and need no power cable. Pneumatic models employ compressed air and are powered by compressors. Such wrenches are common for car service centres, as these models are dust- and waterproof and safe for use in places with high concentration of combustibles. Hydraulic wrenches are the most powerful and are more efficient, heavier, and larger than the above-mentioned kinds of tools. They are typically used at plants, factories, and service stations.

Performance

Once you decide on the impact wrench type, pay attention to its performance. Consider the speed (RPM), number of impacts (IPM), and torque (Nm). It's all simple, the higher each parameter, the better a tool. We will just explain what's behind these values. The RPM number defines the rate of bolting/unbolting, IPM stands for the tightening speed, and torque is a twisting force that helps loosen corroded nuts.

Usability

When it comes to usability of an impact wrench, the size and weight are the foremost aspects that matter. Cordless models are usually heavier than corded ones, and the battery weight directly depends on the motor power. Pneumatic impact wrenches are pretty light, yet they aren't that handy. We mean the annoying air hose, and cables of corded models are about the same problem. The cordless wrenches are weighty, but they can be used anywhere and can be even clipped to a belt, so this advantage compensates the heaviness. Also, we can mention a battery charge indicators and lights that help to work in the dark.

DEWALT DCF899P2-GB

Get Ready to Work Long

When it comes to cordless tools, competent users surely recall such brand as DeWALT, a Black & Decker subsidiary since 1960. We will review the DCF899P2-GB impact wrench powered by the Li-Ion battery. The biggest part of the tool's casing is made of heavy duty plastic, while the head is made of aluminium. The head features the reduction gear that gets fairly hot when the tool works, and the aluminium shell withdraws the heat from it and extends its service life. The tool's weight is 3.3 kg, but it is quite an acceptable result, taking the battery into account. Moreover, the weight is conditioned by the tool's length which is 224 mm, so the wrench can be freely used in cramped spaces.

Review of DEWALT DCF899P2-GB

What About Power?

The brushless 610W motor is powered by a high-capacity battery; the combo delivers a great performance of this electric impact wrench. The torque is up to 950 Nm - enough to cope with any bolt or nut in no time. Also, you will be able to set the torque to 400 or 130 Nm to handle easier connections. This is not all this tool is capable of, though. The DeWALT DCF899P2-GB has a special "breakaway" torque feature for removing the tightest bolts. This is a true breakaway, as the torque amounts to 1625 Nm on the first impulses, then this value gradually drops. Still, it is enough to undo really tough junctions. By the way, when you set the torque to either of 3 modes, the speed and impacts change accordingly to provide a coordinated performance of the entire wrench gear. So, the adjustable settings of this model make it efficient for bolted connections of different materials and sizes.

Top Convenience

Like the majority of similar tools, this DeWALT impact wrench has a built-in lighting. To be more accurate, it's a bright LED. Once you press the start button, the light turns on and stays illuminated for 20 seconds after you release it. So, this LED can be used as a flashlight. Also, we would like to highlight a handy rubberised handle that ensures a comfortable and reliable grip. Portability is a great advantage of any cordless tool, but when it comes with 2 powerful batteries, it's a jackpot! The batteries of this wrench allow doubling the worktime. What is more, both batteries feature special indicators that display the charge status. Finally, we should note that the package includes the rigid plastic box with the wrench, batteries, and the charger inside. Getting this kit, you'll manage to handle a variety of fasteners using the right speed and the impact rate.

Ryobi R18IW3-0

One Battery for All Ryobi Tools

Ryobi was founded in 1943 and was engaged in making offset machines. Since 1968, the company has been producing power tools. The R18IW3-0 electric impact wrench is one of such tools. It is fitted with the 18V electric motor powered by a Li-Ion battery. The body of this model has a rather typical design for such tools. The impact wrench has a rubber-coated grip, a rigid plastic shell with a metal cover on the tool's front, and a battery compartment in the bottom part. We should note that this model comes without a battery, so you should get it separately. However, there's good news for you. Thanks to the ONE+ technology, the wrench is compatible with batteries of the other Ryobi ONE+ tools. Let's say, if you have a Ryobi angle grinder, its battery will easily fit the wrench. Truly convenient!

Review of Ryobi R18IW3-0

Pick the Mode You Need

Buying an impact wrench, you need to be confident it's powerful enough to meet your requirements. The motor of this driver is able to deliver 400 Nm, which is more than enough for your domestic construction jobs. The body features a 3-mode control switch that allows varying the speed and torque. Thus, you may set the first mode and get the speed of 2100 RPM with 180 Nm of torque for rough tightening. The second mode (2500 RPM and 240 Nm) is perfect for final tightening and in the third mode Ryobi will show its best and let you loosen even the most stubborn nuts. In addition to an impact wrench, we recommend you to have a torque wrench in the arsenal which will come in handy for more precise tightening jobs.

Up to 100 Wheels

Speaking about the extra features of this cordless impact wrench, we'd like to mention the Tri-Beam LED lights around the chuck. They allow working in a pitch darkness and hold the driver at any angle, all the working area will be illuminated and you'll see no shadows from a bit or a fastener. Like most models, the lights stay illuminated for a while after the trigger switch is released, so you'll have the time to target the chuck. The wrench weighs 2 kg with the battery attached, and we believe it's fairly comfortable to work long. Our research revealed that this impact wrench is able to fix up to 100 wheels on a single charge, being fitted with an additional 4.0Ah battery, and it's great for using in a small repair shop. The kit includes the 1/4" hex adapter for handling relevant nuts. This model can be offered to those who need a medium-power tool for a car service station.

DEWALT DEWDCF813D2

It Won't Take Much Space

DeWALT offers a wide range of cordless tools for various applications. This time, we picked its DCF813D2 cordless impact wrench. This model is notable for its small size and featherweight. It is possible thanks to a miniature 3/8" chuck which is superb for household use. The tool is 158 mm long, so it won't take up much space in a trunk or toolbox. In addition, you'll be able to work in cramped places, and a weight of a bit more than 1 kg will add to your comfort. The drill's body is made of strong plastic, and the head is traditionally made of aluminium that dissipates the heat from the motor, prolonging its service life.

Review of DEWALT DEWDCF813D2

For Home Repair and Construction Jobs

Having this tool at home, you will always be able to screw or unscrew hundreds of bolts and nuts without a wrench kit. The 147W electric motor is powered by the 10.8V battery and delivers a great force for handling medium fasteners. The rotation speed reaches 2450 RPM, which is a nice performance for a power-saving motor. The impact rate is 3400 IPM, meaning the tool does the job really fast. Taking all these aspects into account, the impact wrench can be used for screwing various woodwork if a conventional drill is too weak. All in all, a wheel replacement and a tire change will be much faster with the DeWALT DCF813D2.

Attention to Details

Just like other models, we have reviewed this one in terms of both performance and usability. Apart from a compact size and small weight, this model has a few more particular features. First of all, it's a backlight. The chuck is fitted with 3 LED lights that are illuminated once the trigger is depressed. The lights go off once the trigger is released, so don't expect a long backlighting. Then, we paid our attention to the trigger that causes the chuck to whirl faster and slower according to how strong you press the trigger. This feature allows a smooth running and slow tightening. As for the drill's body, we would like to highlight the rubber strips that ensure a firm grip and prevent the tool from slipping on a flat surface. Also, as we believe, these strips will protect the tool from scratching. Finally, we can't omit the DeWALT's "habit" to equip their tools with 2 batteries. Speaking more accurately, this drill has 2.0Ah batteries that suffice for domestic tasks. What is more, the kit includes the charger that indicates the remaining battery charge and the branded bag for carrying the entire set. So, as you can see, this impact wrench would be a great helper to any handyman or driver. Whether you own a bike or a car, this model will handle all the fasteners easily and quickly.

Wolf Cordless

A Solid Tool

The next tool on our shortlist is a battery impact gun by Wolf. The greater part of this impact wrench is plastic, while the body is coated with metal. It helps to withdraw heat from the motor and minimise the possibility of overheating. The tool's handle has a rubber insert on the rear panel, which seemed to be a bit strange. The tool looks imposing and is of a standard size, but it's pretty heavy. That's due to a high-capacity 24V battery that increases the overall model's weight. On the other hand, this battery delivers a great power to the motor the capabilities of which are described below. As for the chuck, it's capacity is 1/2", so it's compatible with large bits and allows handling large bolts.

Review of Wolf Cordless

More Voltage, More Power

This impact wrench is able to handle bolts with a torque reaching 200 Nm. The wheels of most cars are tightened at the torque of 120 Nm, while the wheels of buses need 190 Nm, so this impact wrench can be used at any service station. By the way, the wheel replacement requires the use of a car jack in addition to an impact wrench. As for the other features of this Wolf wrench, its impact rate is 2700 IPM, and the speed is 2000 RPM. Thus, the tool will help you quickly change the wheel or assemble other parts of your vehicle.

No Need to Wait

Examining this cordless impact wrench, we noticed that it features nothing but a push trigger and a reverse button. It means that что the tool features a single speed which changes according to how strong the trigger is pressed. Still, the wrench has some advantages. The tool, its battery, and the charger are supplied in a hard gray case for a comfortable carrying. Also, the kit includes 4 hex bits, 17 mm, 19 mm, 21 mm, and 23 mm. So,  you won't have to purchase bits; just start using the impact wrench right out of the box. Of course, the tool comes with the charger that will set the battery ready within an hour. It's really fast and you will be able to resume your work in no time. Moreover, the model can be supplemented with another optional battery. So, the Wolf impact wrench is a great pick for repair shops and car service stations for its great performance and usability. A quick charging and an additional battery allow you using the impact wrench all working day long!

Hold the Tool With Both Hands

This impact wrench is electric but corded, which means you need to plug the power cord into a power socket. Commonly for most impact wrenches, the Clarke tool has a metal hood covering the gear. The tool's handle is coated with rubber pads on the rear, though the grip could be better. The wrench is assembled with decent quality. The tool's weight is concentrated in its front part as it is all-metal, and it makes the difference from cordless models which are well-balanced thanks to their batteries attached to the handle bottom. Therefore, hold this corded impact wrench with both hands.

Review of Clarke CEW1000

Unmatched Performance That...

The performance of this electric wrench is really high! The 1000W electric motor delivers a great power, so the torque amounts to incredible 450 Nm. This is enough for home use as well as for a small workshop. Besides, the impact rate amounts to 3400 IPM, enough to cope with most bolted connections. The tool's speed is 2200 RPM, so you'll be able to perform any task in seconds.

...Never Fails

As for the usability of this impact wrench, we can definitely praise its corded design. If you're going to work in the same place, a power cord is a sheer advantage. No worries about the battery discharge and low power; just plug the tool in and work until the job is done. We particularly liked the forward/reverse trigger switch of this wrench. When the trigger is pulled down, the chuck rotates clockwise, and when the trigger is up, the wrench revolves in the opposite direction. This trigger may be somewhat clumsy at first, but soon it proves its convenience, as it serves as the ON/OFF knob and a reverse button at the same time. In all, we can say that this electric impact wrench is for those seeking an efficient tool for using at the same place for a long time.
