In the case of indoor ceilings, the ceiling is made of reinforced concrete. If drilling with a percussion drill, it will take a lot of effort, but it will not happen when it is used to hit the wall. Therefore, the impact drill is suitable for daily use in the home. But for the punching staff, the hammer drill should be preferred.
When hitting a wall, the hammer drill will be more labor-saving than the impact drill. The key is that the structure and working principle of the two are different. The impact drill needs to be constantly applied by the impact drill during the use, and when using the hammer drill Just apply a little force at the beginning to get the drill to move forward automatically.
