This is one of the the most powerful of the cordless impact drivers and it's a beast of a machine.

Key Features

Power

It can deliver up to 1,800 rpm and 2,200 ipm. It truly has nut busting torque, and this wrench can loosen a bolt tightened to a torque of 1,600 Nm. This is a massive amount of power and should really be enough for any job. 

This is truly enough power for anyone and one customer gave me a laugh in his review by saying ". I also received a letter from Thor himself asking if I would swap it for his hammer"

Electronic 3 Stage Impact Power Selection

These are classed as hard, medium and soft and what we like is the complete control this gives you with the choice of driving power. This lets you control exactly what amount of power you send to the variable speed trigger. 

I expect most will use it on the middle setting and move it up or down as required. 

Brushless Motor

The brushless motor gets rid of carbon brushes, and allows the motor to run cooler and more efficiently for a longer life. It is also electronically controlled to optimise battery energy and use up to 50% longer run time per charge.

Most people will tell you that brushless is much better than using carbon brushes. The tool functions much smoother and feels better, as well as the battery and tool overall life being improved.

A very quick video review

We have looked over all the video reviews and found this great short presentation on this Dewalt power tool. It gives you an instant idea of what to expect as well as telling you all the features and spec in and easy to understand format.

I hope you enjoy watching it as I always think its much better to see a tool in action rather than just reading about it or seeing pictures. This guy is particularly good at explaining the features of the impact wrench and he is well known for demonstrating Dewalt tools.

The Dewalt Brand

The Dewalt brand is a hugely popular brand with the trade professionals. If you look on any construction or building site in the UK, you will find it littered with Dewalt branded tools of all kinds.

Dewalt make the full range of power tools including drills, rotary and demolition hammers, nailers, sanders, saws grinders and many more. They have a very distinct black and yellow coloured brand.

The name itself comes from its founder Raymond E Dewalt and started back in 1922.

In the UK they sell through retailers that include Screwfix, RS Components, Travis Perkins and their own Dewalt Premier Centre.

Our Verdict on the Dewalt Impact Wrench

This is a great choice for removing wheel nuts and we have yet to come across one, where it has not been able to move it.

Not everyone has air tool options and this is about as close as you can get. Really, I think air tools are being surpassed by the quality of these battery models. It won't be long before they are a thing of the past.

For me, this is the ultimate in a high powered impact wrench.If you do a lot of heavy work and want the best, then look no further.
