Impact wrenches give high torque power in short bursts, which permit them to exert a huge force in repeated movements. They come in handy for a variety of purposes including construction, mechanics and metalworking. For mechanics or metalworkers, Electric Impact Wrenches are one of the most useful, force saving power tools. While they resemble impact drivers, they put all of their force into rotation through the anvil instead of a hex chuck.
On general construction projects they, along with power drills are essential and serve multiple purposes. In remodeling projects, demolition hammers and breakers, along with impact wrenches are invaluable for dismantling structures and freeing frozen bolts. Electrical or plumbing installations can be completed quicker employing them along with heat guns, and major assembly jobs will not leave you exhausted with this hardworking tool by your side.
The square drive comes in different sizes, and smaller tools usually have a friction ring system allowing quick release and easy changing of accessories, while heavy duty models often have a larger square drive and use a detent pin for extra security. Impact wrenches are dynamic power tools with various motor sizes which offer different torque potentials and deliver differing impacts per minute, so you can choose one that matches your needs. Most have variable speed settings and all have a conveniently located rocker switch to change between forward and reverse. Rubber or cushioned handles make the tool more comfortable to use, and while smaller models are frequently of an in-line design, heavier models designed for longer periods of use often have a D-shape, and offer adjustable side handles for added grip.
All impact wrenches have a sturdy outer casing so they can take the knocks that often happen on a job site, and many have a convenient sky hook so it's always close at hand. Whether you choose an electric or pneumatic impact wrench, adding this tool to your workshop will make sure you are ready to tackle any task.
