A 18v impact wrench is a very handy power tool for loosening those high torque bolts and nuts. There are many different types of impact wrenches such as a pneumatic impact wrench, cordless impact wrench, battery impact driver and corded electric impact wrench. The cordless impact wrenches are the most popular types of torque drivers with some of the most common types being 12 volt, 24 volt, 28 v and 18v impact wrenches.
Impact drivers are reversible for either tightening or loosening fasteners. What makes these tools different from regular wrenches and sockets is that they have an impact mechanism that produces a shock to the nut or bolt thus freeing it easily. Many of these impact wrenches have a way to set how much torque is applied. This helps so as not to over or under torque the fastener. Let’s take a look at these different types of impact wrenches.
The 18v impact wrench is the most common of all cordless torque drivers. It has the power to handle most any fastening application but has enough torque to handle the tougher jobs that you might have in an industrial tool. For the home user this impact wrench can take care of work around the home or for automotive use. The 18 volt torque driver has enough power to break free lug nuts, loosen rusted exhaust bolts and nuts and remove highly torqued engine nuts and bolts.
For whichever use you might have the 18v impact wrench is the best multi-purpose torque wrench for the money.
