What machine is needed to make a hole in the concrete wall
Electric shock drill. The impact drill works by rotation and shock. A single shock is very slight, but 40,000 multiple shocks per minute can produce a continuous force. It can be used for natural stone or concrete. When the drill is working, there is a adjusting knob in the drill holder, which can be used in two ways, such as ordinary hand drill and impact drill. But the percussion drill USES the internal shaft gear to beat each other to achieve the impact, but the impact is much less than the electric hammer. It is not suitable for drilling in reinforced concrete.
Two words "electric hammer". Small hand tools is only electric hammer, the other a bit more and more heavy, like a professional concrete crusher, is also belong to the category of electric hammer, vibration, commonly used in cement road surface mining. A small hand drill can't shake the dirt.
If you punch holes, you will use a power hammer drill
