Selection Method of Electric Drill

Jul 09, 2019

Take the indoor ceiling as an example. The ceiling is made of reinforced concrete. It will take a lot of effort to drill with percussion drill, but this will not happen when it is used to drill walls. Therefore, percussion drill is suitable for daily use in families, but for perforators, hammer drill should be preferred.


When drilling a wall, hammer drill will be more labor-saving than percussion drill. The key lies in the difference of structure and working principle between them. Percussion drill needs constant force to rotate in the process of using. When using hammer drill, only a little force is applied at the beginning to make the drill move forward automatically.
