Power drills are more suitable for drilling metal, wood, and screwing, but not for drilling concrete.
Hand electric drill is a common electric drill in daily life.
It can be used for screwing screws and drilling holes. It is shaped like a pistol and can be operated with one hand. It is very convenient and small in size.
Girls can operate it with one hand. It does not take up space at home. Generally, the electric hand drill is rechargeable. It can be charged once every three months. It is very convenient to use. However, it should be noted that the temperature of the electric hand drill should not be too high or too low, because once the temperature is not right, it will be dangerous, and the battery should not be discarded at will to avoid explosion.
Because the size of the hand drill is relatively small, it can only do some simple screwing, drilling and other work.
In addition to the function of a hand electric drill, the impact drill can also drill holes in some walls and ordinary concrete.
The impact drill is a little bigger than the hand electric drill, and its shape is similar to that of the hand electric drill. The impact drill can drill holes on concrete. It is a little harder than the hand electric drill. Whether there are quality problems, so as to avoid accidents, if the impact drill is abnormal, it must stop working immediately.
Electric hammers are specially used to drill concrete.
The installation of major electrical appliances requires drilling holes on the wall, and electric hammers can be used. Electric hammers require two hands to operate, and the weight is relatively heavy.
