Technology has been rapidly improving over the years, and impact wrenches are getting more compact and powerful. Even the cordless ones are getting powerful batteries which can rival their corded counterparts. The Werktough IW03 is an ideal example. It’s also one of our budget recommendations.

This cordless wrench is powered by 18v Lithium battery. With the purchase, you’ll be getting a carrying case, a charging dock, and 4PCS CRV sockets. Additionally, you can purchase other sockets for your trailers and trucks. It is super easy to use and can be a great companion for a first-time cordless wrench owner.

Werktough is a fairly new brand and most of you probably never heard of them. But they make some really good tools. Being a lesser-known brand doesn’t mean that this impact wrench is bad. The first batch of the product started selling around July of 2017, and there are little to none info out there. However, I’ve found some short tests and the review is based on that.

It has a simple design, nothing that caught my eye. This one actually looks very similar to Harbor Freight wrenches. It has a considerable weight, and gripping feels solid and firm. Grips are adequate for light to medium use.

This one is a complete kit, and at that price, most manufacturers will only give you the bare tool. But to my surprise, Werktough is giving away a case, charger, and battery along with sockets.

Pros

  • 400ft-lbs torque which is more than any other tool in this price range.

Ultimate Battery Powered impact wrench Buying Guide

To make sure that you end up with one of the best budget cordless impact wrenches in hand you need to understand various facts such as what is it? How do they work? Why use them? These entire questions will be thoroughly answered in our guide. Also, We have covered a massive guide about Impact Wrench Buyers Guide – Everything you need to know

What is an Impact Wrench?

According to Wikipedia “An impact wrench (also known as an impactor, impact gun, air wrench, air gun, rattle gun, torque gun, windy gun) is a socket wrench power tool designed to deliver high torque output with minimal exertion by the user, by storing energy in a rotating mass, then delivering it suddenly to the output shaft.”

This machine consists of a motor which is driven by a power source such as compressed air, electricity or battery. It generates a greater amount of torque which in turn is used to rotate the socket and tightens the loose nut-bolt or remove bolts from a machine.

The direction of rotation can be reversed just with a flip of the switch such that it can work both ways. Also, these torque wrenches can generate far more torque which the human hands can produce.

How does an Impact Wrench Work?

There are two distinct shapes. One of those shaped like a pistol or those like a giant screwdriver. However, despite these completely different shapes both work exactly the same way.

Inside the device, a motor causes rotation inside which exerts the force onto an anvil at the end of the tool. These can be either air or electrically powered. This creates torque and a twisting motion that is usually applied in small bursts of force to twist whatever it’s aimed at.

Inside the motor also has a small hammer that hits an anvil connected to the drive. This force is then exerted onto the socket to break the bolt loose.

By pushing the wrench you’re also applying pressure which helps create friction so that the wrench can better grip or contact the bolt.

The most powerful wrenches are air driven and much lighter but these are not cordless and can only be used with a compressor. Check out the guide on Power Tool Maintenance

Check out this Video about – How an Impact Wrench Works

What Features Should it Have?

The physics of all impact wrenches are fairly similar, though you will see a difference in features and especially the power available. For all cordless impact wrenches, you’re going to find that they’re battery powered. This means they are better for smaller jobs and will usually require the battery to be charged as the power produced will drop as the battery drains.

The two main differences in wrenches are the pistol and screwdriver grips though this is a matter of preference rather than something that affects performance. Wrenches usually come with 5 different socket sizes based on the grip shape. A 1/4” socket can be found on either grip, 3/8”-1/2”-3/4” sockets are usually only found on pistol grips, and 1” sockets are usually only found on pistols and t shaped inline grips.

If you’re working with a bolt that is larger than an inch you’re going to need a more powerful heavy duty wrench that will not be cordless. The key feature of any wrench is the amount of torque it produces, most will tell you their maximum torque while others will have variable torque settings depending on the function. Torque is what you need to pay attention to as it can cause bolts to be over-tightened or too lose.

Why use a Battery Powered Impact Wrench?

Well, there are a large number of reasons to use this tool. I am going to mention a few of them which you cannot deny at all.

  • It can remove the bolt or fasteners very quickly that too without using a lot of muscle power or cause fatigue
  • They are more friendly and easy to use in tight working space and prevents you from the risk of busted knuckles
  • Provide you with a leverage multiple time which can be generated by the manual wrench, thus efficiently removing a stuck bolt or fastener
These can be used to install or remove bolts from a number of places such as tires, frames, engine head and much more. Practically it has unlimited application scope. You can check out our guide about 8 Reasons Why You Should Go For A Cordless Impact Wrench

What to look Before you buy

To choose the best available impact wrench is directly dependent on the type of work which you do but there are certain features which should be considered while making the purchase. Ideally, you must have a look at the below mention features.

  • Torque: 

The higher the torque, the more capable the wrench will be. Having enough torque give you the power to remove and install fasteners very quickly. Look for a wrench with a minimum of 150 ft-lbs or 1800 in-lbs. There are impact wrenches which generate torque in excess of 700 ft-lbs, making them much suitable for professional use.

  • Weight: 

A wrench with lower weight must be given priority. As for small jobs, it doesn’t matter. But when you are working for longer hours a lighter machine is easier to control and handle.

  • Price: 

According to me, it’s the most important aspect of purchasing anything, first identify how much you want to spend and then accordingly select the reasonable features which you can get in your budget.

  • Size: 

The general consideration for size is the smaller, the better as a smaller device would enable you to work in tight spaces. But smaller size will lead to a loss of torque, so I advise you to get a medium sized device.

  • Portability:

If your work demands you to carry your tool at various sites then selecting a model which is light and moderate in size will suit you the best. As they are easy to move around while working and can easily fit in tight spaces.

  • Drive size: 

The most famous drive among users is the 1/2″ size which is capable for most of the application, besides 1/3” is also popular but it has lesser torque and comes in a small package when compared to 1/2″.

  • Torque adjustment: 

This is the feature which I love the most because it enables me to control the torque and thus reduces the chance of over torquing or snapping the bolt head.

  • IPM: 

IPM stands for impact per minute and represents the number of times hammer strikes anvil whereas. Higher these number quickly and tightly the bolt will be fastened.

  • No load speed: 

No load speed is the speed at which the wrench turns without load, choose a lower speed as, and torque is inversely proportional.

  • Ergonomics: 

Look for a wrench that fits your hands perfectly and has a good & comfortable grip material. As it will provide better balance and reduce strain and fatigue while working.

  • Warranty:

Perhaps the most important point when you are looking to invest your hard earned money, most manufacturers offer 1 to 2-year warranty, but occasionally some may give a lifetime The extra warranty comes at an increased price so look what you wish for. There are companies that give different warranty for tool and a separate warranty for the battery, so choose accordingly.

Frequently Asked Question

  1. What is the ideal use of a cordless impact gun?

The reason why some people burn out their tool is that they don’t properly use them for what these tools were meant to do. Don’t expect to remove large truck wheel nuts with a small tool that’s only capable of removing car bolts. You can use them in mechanics garage or in a construction site. The ideal usage scenario would be for car repair.

  1. Which drill voltage should I pick?

As you can see from the list, some tools are powered by an 18v lithium battery, and some are powered by 20v batteries. The higher the voltage, the more powerful the gun is. It will also depend on the type of work that you want to accomplish. For light to medium jobs, any tool that’s powered by a 20v battery should get the job done.

  1. What is the meaning of “Ah” in batteries?

Ah stands for Amperage hours. Normally, the more the Ah in a battery, the longer it will be able to keep its charge. Go for at least a 4Ah battery for longer work time. There are models that lose power more than others, and in the case of rechargeable batteries, they’ll lose charge even if not in use. Pick a reputable brand if you want a longer lasting battery.

Final Verdict

Impact wrenches are specialized pieces of equipment and large bolts may require more than a cordless wrench can handle. Find out the Best one is not an easy task. Although, most of these wrenches are fairly similar the Milwaukee and the Ingersoll are clear winners in power, if not for the prohibitively expensive price!

If you need the power through this extra $70-100 is noticeable as you’re talking almost 3-6 times the power of some of the other drills. If you need to work on the outside and need more power you need air impact wrench For a compact wrench, the Dewalt scrapes through since the Bosch just hasn’t quite got enough power despite its motor.

If you’re looking for a bargain then the Goodyear is a workhorse at barely over $100 it’s well above in specifications for those under the same price. For an all-around tool that has power and is cost effective the Goodyear again is on top, though if you’ve got a system from either Makita or Ryobi you might consider those too since you won’t be worrying about the battery.

None of these are as powerful as air wrenches, but you’ll still get decent days to work out of most of them. Once you get over $150 price really makes a difference in power so deciding whether you really need that extra few hundred ft. lb of torque is important if that’s your selling point.
