Best Impact Wrenches 2021

This review is aimed at showing the best impact wrenches out there. While there are so many wrenches, only few can deliver a perfect job. We have taken time to research on them, if read through this review, you will discover for yourself the best impact wrenches for you.

BUYER’S GUIDE

The impact wrench you buy will depend on what your main use for it will be. Air powered options are favored by professional tradesmen and mechanics as their power supply isn’t likely to run out half way through a job.

Air powered, pneumatic impact wrenches are generally more powerful and lighter to use, with most professionals favoring them for home construction and mechanical work.

However, electric impact wrenches provide more than enough power for average DIY tasks, these tend to be the favorite choice as users prefer something a bit more mobile for home use and may not have access to an air compressor.

An impact wrench is selected based on different factors, the three main ones being the spike torque provided, the impacts per minute and the power supply.

Torque

The torque is measured in Newton-meters (Nm) and represents the twisting force that will be applied to the bolting and unbolting action. To give you an idea, a wheel bearing is tightened to about 120 Nm. Consult a torque chart to get a better understanding of the required torque. Don’t guess or you’ll look like a tool!

Impacts per minute

The impacts per minute determines the tightening speed. The higher the number, the more torque is applied to the offending screw or bolt.

Power supply

Corded

Pretty straight forward, just have to worry about the spike torque provided and the impacts per minute.

Battery

The higher the votlage (V) and the amp hour (Ah), the more the power and autonomy the impact wrench will have. Lithiumion (Li-Ion) batteries are commonly favored because of their rapid recharging and the lack of memory effect. Most drivers will be equipped with this type fo battery.

Pressurized air

It is important to verify that the air pressure and air flow required by the impact wrench and those supplied by the compressor match to obtain optimal use.

Other factors to help you make the right call include:

  • The tool’s weight is important for better maneuverability;
  • The anvil’s coating;
  • The ergonomics of the handle ;
  • A variable speed trigger ;
  • The spiking speed relative to the impacts per minute;
  • The number of batteries, when applicable;
  • The spiking torque – for maximum loosening force;

Size:

The size of an impact wrench is mainly down to the bolts it will need to undo and the torque that is required.

For example: A 1005Nm impact wrench (a large tool) will work with M12 to M30 bolts (M12 = 12mm diameter, M14 = 14mm diameter etc.). A 280Nm impact wrench (medium size) will work with M8 -M16 bolts. The smaller compact 180Nm tool will work with M8 – M16 bolts.

As such, it is very important that you choose the correct impact wrench for the size of the bolt that needs to be tightened or loosened.

Speed:

Some impact wrenches have a selection of speeds. Increasing the speed setting on an impact wrench will also typically increase the power (torque).

Having the ability to change the speed setting on an impact wrench is useful as it can help to prevent damaged caused from the use of too much force.

Chuck type:

There are only a few different chuck sizes available for impact wrenches, which are are all square. They come in 3/8″, 1/2″, 3/4″ and 1″ sizes. The chuck sizes correspond to the impact sockets you have available, or wish to use on the machine.

Application:

Steel works will usually require very heavy duty robust impact wrenches with a high torque output. Car industries typically use cordless 18v impact wrenches, which are very common among tyre companies for removing wheel nuts.

Some impact wrenches are suitable for scaffolding but these don’t require a high torque output. Most manufacturers will state whether an impact wrench can be used on scaffolding or not.

Impact wrenches can be used around the home to tighten various bolts, but make sure that you don’t use too much torque as this could result in damage.
