Difference Between Impact Wrench vs Impact Driver
Before knowing the differences between an impact driver and an impact wrench, it is important to understand what each tool can do.
Impact Wrench
An impact wrench is a power tool used for loosening or tightening various nuts and bolts. Impact wrenches have a hammering mechanism that features strong, quick blows to bolts that would otherwise require extensive manpower, making this tool suitable for even rusted or oversized bolts that are difficult to turn.
Impact Driver
An impact driver combines a drill’s rotational force with bursts of impact similar to a hammer drill. This force helps drive the fastener past points of resistance. Impact drivers are usually lighter than other types of drills, making them easier to use in some instances. They handle large screws and bolts more efficiently than compact drills and offer two to three times for torque than drills.
Despite the similar names, there are several distinct differences between an impact wrench and an impact driver. The main differences between the two tools include:
- Impact drivers are primarily used for drilling long screws into metal or wood, whereas impact wrenches loosen or tighten nuts and bolts.
- Impact drivers are commonly used by a wide range of DIYers and for many types of renovation projects. Although impact wrenches are good for several different projects, you will primarily find them used in the automation industry.
- Impact drivers are easier to use than impact wrenches, which are generally heavier and more powerful.
If you determine that you need both an impact wrench and an impact driver, there are a few tools that combine the capabilities of both tools, but it is usually best to get each tool individually.
With these differences in mind, you can begin to determine whether it is an impact wrench or an impact driver that is the tool that you have been missing from your toolbox. To help you decide, check out the suggestions on the best of each tool below.
