Most electric screwdrivers are designed for professionals, so you should distinguish between general household and industrial electric screwdrivers when purchasing.
The difference between the industrial grade and the general household electric batch is mainly in power. The industrial-grade electric screwdriver power is relatively large, generally around 30V, to facilitate the professional to reduce the workload;
Generally, the electric batch for household use is relatively small, and the workload is relatively small. Therefore, the power of the electric batch does not need to be large, generally about 5V, and the electric screwdriver with a larger power is larger in volume. The straight-type electric screwdriver has a power of about 3V and is suitable for removing screws on some small items.
Household electric screwdrivers generally have low requirements for torque accuracy, and only need to meet the function of locking screws, so the price is lower;
Industrial-grade electric screwdrivers have high requirements for torque accuracy and are equipped with functions such as counting and alarming, so the cost is high.
There are also some differences in classification.
Sometimes industrial-grade electric screwdrivers can also be used for furniture assembly, torque requirement is the major factor in the selection.
