Impact wrenches are among the most cost-effective tools you can buy and instantly improve your DIY life. I waited years before I bought an impact wrench and immediately regretted not having bought one earlier. Do not be me ̵
Many people refuse to buy an impact wrench when they learn that a power drill does everything an impact wrench does, and more. After all, a drill can drill holes (right there in the name) and screw in screws. For this reason, the tool is usually referred to in downtown shops as a drill / impact wrench.
Impact wrenches, on the other hand, can only drive fastening elements (such as screws, anchor bolts or anchor bolts). However, if you know what an impact wrench is and how it works, you want to own it.
What is an impact wrench?
An impact wrench is a tool specially developed for driving fasteners. At first glance, the body of an impact wrench looks like a drill, and you might mistake them. The main differences make the impact wrench better in its work than a drill.
A drill presses a motor to rotate the drill chuck holding your drill or screwdriver. It's simple and effective, but does not offer much torque.
On the other hand, an impact wrench contains additional components. If you take one apart, you will find a motor, a spring, a mortising hammer and a rod-shaped anvil. When you pull the trigger, the motor turns like a drill.
When the impact wrench encounters resistance (for example, through the wood you screw into), the spring snaps into place by pulling back. It then releases, pushing the rotating hammer forward. That strikes and turns the anvil turning the collet holding your driver bit. Here is a video showing the process in slow motion.
If you use an impact wrench, you can feel and hear the anvil beats. It is easy to imagine that the impact is a pure downward force, but it turns more than vertical. This results in a high torque without much pressure on the arm. Therefore, impact wrenches can drive better screws than drills.
When should an impact wrench be used?
If you've come along You already have a good idea of when to use an impact wrench. If you need to drill pilot holes, still use a drill. While a drill has a chuck that can accommodate either round or hex drills, an impact wrench uses a collet system that only accepts hex drills that are used to drive in bolts or draw bolts with an adapter. An impact wrench does not need drills.
However, if you want to hammer in a fastener, you must pull out the impact wrench. The higher torque and higher power make it easier to drive fasteners into the material (wood, metal, etc.). The thicker the material, the clearer the difference becomes.
Not only is the impact wrench faster, but it is also less likely to remove a screw, resulting in cleaner results. That's true, even if you forgot to drill a pilot hole.
In picture I above I had two screws screwed into a thick plate. I did not drill full pilot holes, just a start hole to keep my screws straight. I used a drill for the left screw, and I used the impact wrench for the right screw. As you can see, the drill has removed the screw on the left side while the impact wrench did not.
Impact wrenches save you extra time as they not only drive fasteners quickly and cleanly. If you have both a drill and an impact wrench, you will spend less time changing parts. With just one drill insert a drill bit, then a screwdriver, then a drill again and repeat the process. You only exchange the tools if you own both.
Inserting a screwdriver into an impact wrench is easier and faster. For a drill, you need to insert the drill, hold the chuck, then pull the trigger and try to get a tight fit. Using an impact wrench, gently pull out the collet, push the drill in and release it. That was it's.
Adding an impact wrench to your toolset will save you more than enough time to justify the cost.
