The electric hand drill is the smallest power drill among all electric drills, and it can be said that it is more than enough to meet the daily needs of the family. It is generally small in size, occupies a small area, and is quite convenient for storage and use. Moreover, it is light and easy to exert force when in use, and it will not cause too much noise pollution to disturb the surrounding neighbors. It can be said to be a very considerate tool. So how to choose a hand drill? We can start from the following aspects:
Check the power supply
Hand drills have different power supply methods and battery types. We need to first look at its power supply when choosing. Regardless of the power supply method or the battery type, the one that suits our usage habits is the best.
1.1 Power supply mode
The power supply methods of the hand drill are mainly divided into two types: wired and wireless, of which the wired type is the most common. It can be used normally as long as the cable plug at the end of the electric drill is plugged into the power supply. Its advantage is that it will not stop working due to insufficient power, and its disadvantage is that it has a very limited range of motion due to the limitation of the length of the wire. The wireless power supply uses a rechargeable type. Its advantage is that it is not bound by wires. The disadvantage is that the power is easily used up.
1.2 Battery Type
The rechargeable hand drill needs to be installed with a battery before it can be used, because it is often charged repeatedly, so the choice of battery type also determines the feeling when using it. There are generally two types of batteries for rechargeable hand drills: "lithium batteries and nickel-chromium batteries". Lithium batteries are lighter in weight, smaller in size and lower in power consumption, but nickel-chromium batteries are relatively cheaper.
Look at the details of the design
In the selection of hand drills, we also need to pay attention to details. The detail design is so small that it affects the beauty of its appearance, and it is so large that it determines its function, safety in use, and so on. Specifically, in the details of the hand drill, we can pay attention to the following points:
2.1 Speed regulation
The hand drill is best equipped with a speed control design. The speed control is divided into multi-speed speed control and stepless speed control. Multi-speed speed control is more suitable for novices who have rarely done manual work before, and it is easy to control the effect of use. The stepless speed regulation is more suitable for professionals, because they will know more about what kind of material should choose what kind of speed.
2.2 Lighting
When the environment is dark, our vision is not very clear, so it is best to choose a hand drill with LED lights, which will make our operation safer and see more clearly during operation.
2.3 Heat dissipation design
During the high-speed operation of the electric hand drill, a large amount of heat will be generated. If the electric hand drill is overheated without a corresponding heat dissipation design, the machine will crash. Only with the heat dissipation design, the hand drill can better ensure the safety of your use.
