How to choose the tools for general family use?

(1) The electric screwdriver, as the name suggests, is simply understood as the electrification of the screwdriver, generally provides a torque range of about 0~5Nm, and the daily use environment is to play screws.

(2) Electric hand drill, torque range 0~30Nm, torque covers the electric driver, family use environment, can cover the use of the electric driver range. It intersects the electric screwdriver speed faster, thousands of RPM gives it more functions, such as drilling and other use cases.
The above two products only provide rotation, while the following two products add longitudinal motion while rotating. Axial work gives them more power in the axis, so they are generally used to open holes.

(3) Impact Drill, as the name suggests, rushing, it has a mechanical structure in the longitudinal direction, can be continuously forward in the process of bit rotation, with high-speed rotation to achieve more labor-saving opening purposes, the speed can generally reach 2 to 3 times the hand drill.

(4) Electric hammer, the name is so imaginative that when I first heard it, I thought it was Thor's sledgehammer. In fact, the electric hammer is a greater strength of the impact drill, the mechanism uses a coarser mechanical structure, when used, you can feel the obvious sense of piling. It's like a giant fascia gun, a real miracle product that can punch holes in concrete.

Combined with the use scenario of my family in the past 10 years, it is summarized as follows:
1. Home appliance maintenance; 2. Home improvement; 3. Other miscellaneous items. In terms of frequency of use, the hand drill is the main force of my home, and the electric hammer is a must.
