Impact Wrench Buyer’s Guide
Impact wrenches are available as cordless, mains powered or air powered.
Cordless wrenches are very convenient. Their portability means they are ideal to use if you are out and about. Mains powered impact wrenches offer excellent power and continuous use but obviously are a little less versatile as they require a plug socket. If you are a mechanic and work in a garage, then an air powered wrench used in conjunction with an air compressor may be more suitable.
When choosing an impact wrench your prime consideration is torque. This is measured in Nm (Newton metres). The higher the torque the more easily the tool will be able to accomplish tough applications such as undoing seized bolts. The other specification you will see is either bpm or ipm (blows or impacts per minute). Again, the higher the number the more powerfully and quickly you will get the job done.
If you choose a cordless impact wrench you will find some come with batteries and some as bare tools. If you have other power tools that use similar batteries, you can save money by buying the bare tool.
Other things to look for in an impact wrench include a brushless motor – this type of motor is more efficient and longer lasting compared to a conventional motor. Variable speed control provides more control and is suited to more delicate tasks. Finally an LED task light is useful, particularly for work in darker areas such as under a car.
You should also consider the tool’s weight and ergonomic design to make sure it is comfortable to use and suitable for your needs.
What is an impact wrench?
An impact wrench is a tool that can be used to tighten or loosen various fixings extremely quickly even if they are rusted or otherwise immovable. If you are a fan of Formula One racing, you’ll have seen pit stop engineers use impact wrenches to change the wheels of a car in seconds.
How does an impact wrench work?
An impact wrench has a motor that is powered by electric mains, air or battery. The motor applies a sudden, intense twisting motion in short bursts. The brief but powerful bursts of force either loosen or tighten a fixing with incredible efficiency.
Impact wrenches also have a very high torque output. This is the rotational equivalent of linear force.
How do I use an air impact wrench?
An air impact wrench looks a little like an old fashioned drill. It has a metal body and a trigger. The trigger allows you to exert the right amount of air and torque pressure.
The air impact wrench is connected to a compressor. Attach the hose to the compressor before attaching the wrench.
What kind of air compressor do I need to power an impact wrench?
You can choose between a portable and stationary air compressor.
Compressors are measured in psi (pounds per square inch) and deliverable cfm (cubic feet per minute)
The wrench instructions will state the psi and cfm requirements. Choose an air compressor whose specification is a little higher than the psi and cfm required by your impact wrench to ensure that it will not be under-powered.
What can you use an impact wrench for?
An impact wrench is invaluable for loosening screws and bolts that just won’t budge by any other means. Mechanics use them a lot but they can be used for pretty much anything an impact driver can be used for too. Using an impact wrench ensures anything you build is really secure. Whether you are fixing kitchen cupboards to the wall, building a deck or gazebo, using an impact wrench for scaffolding, changing a tyre or maintaining your lawnmower, an impact wrench can make your life significantly easier!
