There are many types of power tools, such as electric drills, angle grinders, circular saws, electric hammers, etc. 16 types, which are also divided into two categories for household or industrial use. There are many types of industrial power tools, and it is difficult to directly introduce how to choose. , And household types will be much less, it will be easier to understand, so I will talk about how to choose household power tools.

There are two main scenarios for daily household electric tools:
1. The installation of daily furniture, such as the installation of online shopping desks, mainly requires tools for screwing; 2. The installation of daily wall-mounted supplies, such as wall-mounted paintings, mainly requires tools for wall drilling. For the above two scenarios, the tools required are mainly electric hand drills and percussion drills or electric hammers. Let’s first understand the use of hand electric drills, percussion drills and electric hammers: Hand electric drills: mainly used for flat drills, suitable for the following materials Drilling: wood, metal, thin plate, glass and ceramic tiles; if it has the function of forward and reverse rotation, screws can also be screwed; not suitable for drilling walls and stone. Impact drill: It can be used for drilling holes on brick-concrete and light-concrete walls (not suitable for reinforced concrete), mainly for household use. If you need to work on concrete for a long time, you need to use an electric hammer; electric hammer: mainly used for concrete and Drilling of reinforced concrete is an essential equipment for professionals.

For the daily installation of screws, a hand electric drill is enough, but if the wall is to be drilled, a percussion drill and an electric hammer are required. The difference between the two is that the electric hammer can hit the reinforced concrete, which is the load-bearing wall, and the impact Drills mainly hit brick and concrete walls, that is, non-load-bearing walls. Some people may ask how to distinguish between load-bearing walls and non-load-bearing walls. Here is a simple way to teach you to listen to the sound by tapping. If the tapping sound is clear, it is not a load-bearing wall. If it is thick and no echo, it is a load-bearing wall. Our daily household use is still based on non-load bearing walls, so the basic impact drill is enough. In other words, for our daily home use, hand electric drills and percussion drills are enough. It is best to buy a hand electric drill and percussion drill multi-function electric drill, which is convenient and labor-saving.

Here I suggest that the broad masses of male compatriots prepare an electric toolbox at home, which will play a great role when needed.
