How to choose a good electric screwdriver? Professional sharing of the most detailed selection guide

2023-03-08

Electric screwdriver, also known as electric screwdriver, is an electric tool used for tightening and loosening screws. It is equipped with a mechanism for adjusting and limiting torque, and is mainly used in assembly lines. It is one of the essential tools for most production enterprises, especially in the assembly industry. But due to the high market demand, more and more brands of electric screwdrivers have emerged, and the quality of electric screwdrivers varies. How to choose electric screwdrivers? Here is a detailed selection guide to share with everyone!



1. Determine the purpose

Electric drivers are divided into household and industrial use, with the main difference being the power size. Household electric drivers have relatively low power and are relatively less used, and the input power is indeed not as large. The power setting for professional use is relatively large, so that professionals can reduce workload and not feel so tired during long-term use. Therefore, before purchasing, the first step is to determine the purpose of purchasing an electric screwdriver, whether it is for household or industrial use.

2. Pay attention to torque setting

Compared with ordinary electric drills, electric drills have added a "fixed torque" function, which means that if the torque exceeds a certain level, it will jump out of the air and will not blindly twist and burst the screw hole. In addition, there are also forward and reverse gear positions to loosen and tighten, and adding a low speed gear is more suitable for tightening screws. After all, the torque is not suitable, and work efficiency cannot be improved. For example, if the torque is too small, it cannot be twisted down, and if the torque is too large, it is easy to damage the product and cause serious slipping. Therefore, it is best to choose an electric screwdriver with precise torque setting, moderate maximum torque, and multiple gear adjustment.

3. There are multiple speeds for better performance

Generally, better electric drivers have several different speed options, including high, medium, and low speeds. You can choose different speeds according to different needs, as low speeds can easily affect efficiency. So try to choose an electric screwdriver with multiple speed options. Generally speaking, big brands do a great job in this area, such as quick acting intelligent tightening. Their family has been focusing on the tightening field for more than a decade. The electronic drivers they produce not only have a variety of styles, but also are precise and durable, which are loved and recognized by users. Currently, their service points are spread across multiple cities across the country. It is understood that their brushless intelligent electric screwdrivers are exported to more than 200 countries and regions worldwide, with a cumulative global sales volume exceeding 1 million units.


4. Check the appearance of the machine

The appearance of a good electric screwdriver should be uniform in color, with no obvious shadows or dents on the surface of plastic parts, no scratches or collision marks, assembly misalignment between shell parts ≤ 0.5mm, smooth and beautiful aluminum casting coating without defects, and the surface of the entire machine should be free of oil stains and stains. When held by hand, the handle of the switch should be flat, and the length of the cable should generally not be less than 2 meters.

5. Check the authenticity of nameplate parameters

The nameplate parameters of the electric screwdriver should be consistent with those on the CCC certificate. The manual should include detailed addresses and contact information of the manufacturer and manufacturing plant. There should be a traceable batch number for the product on the nameplate or certificate of conformity.

6. Observe if the function is normal

Hold the electric screwdriver with your hand, connect the power, frequently operate the switch to start the tool frequently, and observe whether the on/off function of the electric screwdriver switch is reliable. You can pay attention to whether there are any abnormalities in the TV and fluorescent lights on site to confirm whether the electric screwdriver is equipped with an effective radio interference suppressor.

Additionally, you can try powering on the electric screwdriver and running it for one minute, holding it with your hand during operation. If there is no obvious abnormal vibration in your hand, then there is no problem. At the same time, there should be no abnormal noise during operation.

7. Look at brand qualifications

With the widespread application of electric screwdrivers in the industrial assembly field, various manufacturers of electric screwdrivers have sprung up like mushrooms after rain. Consumers are faced with a mix of good and bad brands, and it is often difficult to choose. At this point, it is particularly important to identify the brand qualifications of manufacturers. It is recommended that everyone choose manufacturers with brand qualifications.

The above is how to choose a good electric screwdriver. You can refer to the above points in the selection process. At present, compared to other brands producing electric screwdrivers on the market, the electric screwdrivers with quick action intelligent tightening have a better reputation both inside and outside the industry, and their quality is also more guaranteed. If you need it, you can go and learn more on your own.
