Strongest Cordless Impact Wrench Review

There are some jobs which need serious power to finish them off, and these jobs simply can’t be done by hand. Power tools are an important part of your home maintenance kit, but what do you do when you need some heavy duty power behind you? Twisting big bolts, changing tires on large vehicles, and other harder to finish jobs all need something a little more than your regular manual tool. Thankfully, this is where heavy duty tools come into the fore, and a cordless impact wrench with some serious power behind it, is certainly worth having in your tool collection.

Cordless impact wrenches are ideal for many jobs around the house, but they are also used commonly in the automotive business, for heavier jobs. There are many cordless impact wrenches that can serve both purposes, meaning you can be working under the sink one minute, and out in the garage the next. 

What is an Impact Wrench?

Impact Wrenches

We eluded to the fact that an impact wrench is a power tool, and it comes in various different strengths and speeds. If you’ve ever tried to undo an extremely tight bolt or screw and found your knuckles having taken the brunt of it in a tight space, you’ll understand why an impact wrench is the best option to go for. Once your wrist gets into a certain position or angle, it can be nearly impossible to get any sort of rotation in. This tool basically applies rotational power (torque) to the object, and it either loosens it, or fastens it, depending on what you’re trying to do. Hard to reach places are a thing of the past with new and improves cordless compact wrenches. 

Cordless Impact Wrenches

There are several different types of impact wrenches on the market, which we will discuss little more shortly, but for this particular review we are looking at the cordless variety. A cordless impact wrench is powered by battery, and it is recharged as and when necessary, usually after a heavy duty job. Many shops and garages use this particular tool on a very regular basis, but even if you only use it for the odd household job, or perhaps to change a car tyre, it is certainly a very useful item to have. There is nothing more annoying than trying to get into a hard to reach place, only to be yanked back by a cord, or lose power all together. 

Types Of Impact Wrenches​

We mentioned that there are different types of impact wrench you can purchase, and aside from the portable version, these are usually pneumatic or electric. The pneumatic version is usually used in businesses, such as garages or repair shops, and it is powered by an air compressor. The electric version is powered, as the name suggests, by the mains power supply, and is plugged in, with a long cord connecting the tool to the mains plug. However, do not be afraid of the electric wrench running out on you mid-project. These wrenches have some heavy duty batteries that can last for hours before even showing any signs of running low on juice.

How To Choose the Right Impact Wrench

What do you need to look at when choosing the correct cordless impact wrench for your needs?

  • Price – Shop around for the best price within your budget range.
  • Weight – Lightweight models are going to cost you a little more, but this is perhaps worth it if you’re going to be using the tool for working overhead a lot, or for long periods of time. Holding this particular tool can be cumbersome, so a lightweight version would work best for regular users.
  • Power – What are you going to be using the tool for? If you’re just looking to use it for the odd household job here and there then you can probably save cash and downsize your choice to a smaller version; if however you are going to be using it regularly, for bigger jobs, then you need to look at the horse power and output of the model you go for.
  • Ft-lbs torque amount – The amount of torque basically tells you how strong the impact wrench is, and again, you need to look at what you’re going to be using it for. Torque is rotational power, and the higher the amount, the stronger the machine.
  • Warranty – Check the warranty and what is included in the original purchase. This will save you money in the long run.

People can spend hours in a hardware store looking at wrenches and reading the fine print by the price tag. However, you can see all that information, and more, here with our reviews of the wrench. We break each wrench down into categories, such as Torque, Weight, and Voltage. On top of that, we look at key features each wrench has, and how it is different from others. Hopefully you can leave here with a better idea of what you are looking for, and with a plan of what wrench to get. Without further ado, here are some heavy duty wrenches that are sure to get the job, whatever job it is, done with ease.
