For this post, I have put together a collection of the best impact wrenches currently available.
Similar in size to a cordless drill, these powerful tools will help you save time and effort removing stubborn bolts and wheel lug nuts.
Impact wrenches work by spinning a mass within the unit either by air or electricity (corded or cordless) then quickly connecting it to the anvil, which is the portion connected to the socket. Since this “hammering” weight does not stay fixed to the shaft you don’t have to feel the high twisting power of the tool, instead this force is transferred to the nut. If you want an exact torque, you may also want to look at getting a torque wrench.
I have included a range of options below including air-powered (requires an air compressor), electric (corded) and cordless so you can find the right one for you.
The following impact wrenches use the latest innovative components to meet your needs and help to ensure you do your best work.
