How to choose a electric screwdriver1. Choose by power source: Screwdrivers can be roughly classified into electric screwdrivers and non-electric screwdrivers. Electric screwdrivers are mainly divided into two types, one is the rechargeable type, and the other is the cordless type. The electric screwdriver is easy to use because the power is supplied by the rechargeable battery, and there is no need to worry about the length of the power cord. Also, it can be used in situations where the power cord is difficult to attach. If you have the power cord, it is convenient to use the cordless electric screwdriver that can be used with the power cord. In addition, it can be used in a wider range of places, so it is recommended to choose a model that can be used in both ways. 2. Choose by screw drive type: There are two types of screw drives, one is the spindle type and the other is the piston type. The spindle type has a larger diameter and is suitable for driving screws with a large head diameter, and the piston type has a small diameter and is suitable for driving screws with a small head diameter. When choosing a screwdriver, check the type of screw to be driven and choose the one that matches the screwdriver. 3. Choose by functionality: There are screwdrivers with only one screwdriver and screwdrivers that come with a wide variety of attachments such as bits and drills. It is convenient to use the type with one screwdriver because it can drive screws and bolts with one screwdriver. In addition, there are some models that come with a drill, so you can drill holes and tighten bolts all in one. There are also models that can be used by changing the screwdriver type and size, so please choose a model that suits your purpose.
