Types Of Wrenches
Corded Impact Wrenches
Corded impact wrenches must be plugged into an electrical socket in order to work. They feature an electric motor at the back which transfers movement to the unit’s output shaft.
Corded impact wrenches offer advanced torque regulation and speed. They’re also a portable option since you do not require an air compressor.
The drawbacks with these impact wrenches are that they are pricier than air tools, and are also susceptible to overheating due to multiple moving parts.
Cordless Impact Wrench
Cordless impact wrenches are powered with a battery, which makes them portable. This means you can easily transport them and take them wherever you need to.
Due to their cordless design, they are also ideal for working in constraint spaces because no power cable gets in the way.
The only downside to cordless impact wrenches is that rechargeable batteries drain fast when using them continuously, which means you’ll have to charge them before commencing work.
They are also the priciest option, plus they’re heavier than both pneumatic and corded models.
Pneumatic Impact Wrench
Pneumatic impact wrenches use compressed air to operate and are a common choice for automotive repair shops, plants that manufacture heavy equipment, vehicle assembly lines, etc.
These impact wrenches feature a basic design and are therefore a more affordable choice.
Since they do not have electronic parts, they do not malfunction easily. They’re also not susceptible to overheating.
The heat that is produced by the moving parts inside the unit is cooled down by the compressed air. Thus, you can use these impact wrenches for extended times without the risk of overheating.
Electric Vs Air Wrenches
Electric models are not as powerful as their compressed air counterparts, but they still pack a powerful punch.
They are incredibly useful around the house where you don’t have an air tank at your disposal.
You can choose between a corded wrench or a battery powered unit. However, keep in mind, battery powered options are heavier due to the additional weight of the battery.
Air wrenches are commonly used in vehicle repair shops and typically have an air tank attached to one end. Compressed air is incredibly powerful which makes them a good fit for an impact wrench.
These wrenches are usually lightweight since they do not need batteries or a motor to power them. Just remember you will always require a full air tank.
Features To Consider
Depending on the type of power source the wrench uses, they are usually divided into 3 categories: electricity, hydraulics, and compressed air.
Compressed air and electricity powered wrenches are commonly used among car mechanics and contractors, while hydraulic wrenches are primarily used for industrial purposes.
Shape and socket size
Impact wrenches that are cordless feature two body types – pistol grip and inline.
The inline option resembles a big screwdriver with a grip at the back of the anvil and hammer. The pistol type looks like a gun with the grip located under the motor.
Cordless impact wrenches use various socket sizes, which are engineered to fit bolts and nuts of various sizes.
An inline wrench is ideal for performing tasks in constrained spaces where a pistol type impact wrench won’t fit, for example fixing cars.
The torque is an important consideration and all impact wrenches have a particular maximum torque range. They aren’t restricted to just one amount either.
Most models permit you to pick different torque speeds to match the project. It is crucial to use the precise amount of torque for a job because if you don’t, it could have devastating results.
Always check for wrenches with design upgrades, for example, all metal construction for the housing, or plastic overmolds that protects the unit against damage when dropped.
An impact wrench with a brushless motor has fewer moving parts, meaning they typically have a longer lifespan with a reduced risk of components malfunctioning or breaking.
Maintenance is also a lot more straightforward on those.
