For the most part, impact wrenches are engineered for loosening and fastening sockets. Impact wrenches are utilized for things you would usually use a wrench for when doing automotive work and building furniture. When a normal wrench just can’t cut it for certain reasons, obviously your only weapon is to use an impact wrench.

Impact wrenches are primarily powered by compressed air through air compressor machines, but some units utilize electricity and even hydraulic power. But the most powerful kind of impact wrenches is those air-operated pneumatic wrenches.

Now when it comes to power, the secret behind the exceptional performance of an impact wrench is its torque delivery. Electricity or air gives the wrench’s motor an abrupt burst of power, thus generating an intense rotating motion which can break seized nuts instantly. Technically, impact drivers are far inferior to impact wrenches in terms of torque.

Overall, impact wrenches are the perfect choice if you’ve got projects or tasks that require tremendous amount of torque. So if you’re still not sure what model and brand to get, then look no further because we will show you two reliable impact wrenches from Porter-Cable that will absolutely get your job done effectively and efficiently.
