This time we are going to bring out the difference between the hammer drill and impact drill. There are a large number of peoples who are not familiar with the prime aspect that makes a hammer drill from the impact dream. So the main difference is the direction from which they each exert additional force on their twisting action. A hammer drill exerts a huge force directly into the bit as it hits the material being drilled. On the other hand, an impact driver multiplies the force being delivered perpendicular to the bit.
Therefore, what is the difference between the hammer drill and impact drill? So let us find out in this article.
You all will be amazed that in appearance-wise both hammer and impact drill look more or less the same but if you take a close look than you will find the key difference. A hammer drill is an electric power tool that is used for drilling masonry, on the other hand, an impact drill driver is a tool used for driving screws that demand high torque.
Before driving further let go through with the basic detailing of both tools.
Hammer Drill
Hammer drill fulfills a very particular role which is to pulverize holes in concrete, brick marble, granite, and other similar materials. There are two types of hammer drills, the regular hammer drill, and more powerful rotary hammers.
Impact Drill
The impact drill is also known as Impact drivers fulfill a completely different role when compared with hammer drill. The main motive of the impact driver is to loosen or drive fasteners, screws, and bolts into the material. They can also be used to drill holes, hence you can pretty well understand why this tool is named as Impact drill.
Below is a chart, it is clearly depicted the difference between these two powerful tools.

With this above information, you’ll able to understand, when you see a hammer drill or cordless impact drill you will be aware of the functionalities that are performed by these tools.
These two tools might look similar but they function differently. We all know that most of our works are commanded by electric tools so it is very important for us to know the functions of each electric tool.
Many times we get deceived by the appearance of electric tools. They might look more or less similar but their functions are not. It is very important for us to be electrically sound so that we pick the correct tool in order to fulfill any specific task.
