These three kinds of electric hammers are not good, because the change-over switch is on them. The electric hammer equipped with the change-over switch will hit the wall when punching holes in the wall, damaging the change-over switch. Such an electric hammer is also not conducive to punching holes in the wall.
The picture below shows the electric hammer I bought.
Which is better, Shanghai electric hammer or Dongcheng electric hammer?
The pit shape of the drill is related to the chuck structure of the electric hammer!
Generally speaking, the chuck can only match the shapes of the corresponding pits and grooves. As for what shape is completely designed by the electric hammer manufacturer, each family is different and cannot be used universally. Personally, I have long felt that we should unify the standards and save trouble!
Generally, square handle four pits are the most common, and the well-known domestic brand "Dragon Brand" electric hammer is used. Later, many electric hammers imitating the dragon brand used this design, which was the most widely used and common in the market.
Two pits and two grooves are Bosch's patents, and the five pits you mentioned are also Bosch's special drills.

How about Shanghai industrial electric pickaxe?
In fact, there are many miscellaneous brands in China that are similar to this brand. It can be seen from the gears and connecting rod rotors that Shanghai workers are generally acceptable in China, at least they have not been accused. You'd better buy a genuine Dongcheng electric hammer. Dongcheng's rotor is very good, and it is made in Jiangsu. Shanghai workers say it is made in Shanghai, but it is actually made in Zhejiang. Hehe, the real Jiangsu goods are better than Zhejiang goods.

Shanghai workers play the Shanghai Workers' Card, regardless of whether Jester is Jielida or not, in fact, they don't play the Shanghai Workers' Card.
By the way, the tools in Shanghai are not so good either.
I want to buy an electric hammer and pickaxe for punching and decorating. The following three models are good: Gong Hu 688, Dongchuan 5024B, Guangzhou.

As shown below, I bought one, but I don't feel as good as Dongcheng.
