Personally, lithium batteries are the future trend, especially for home use. The first choice is to choose the lithium battery tool, which is the charging tool. But the trend belongs to the trend, and we must also understand the advantages and disadvantages.
Charging tools: convenient, not limited by nearby power supply, and can be used outdoors, but generally the power is slightly weak, and the endurance is limited, and the price is expensive.
At the same time, there is a long-term advantage. Each brand has its own battery platform. After buying a charging tool, you can buy other tools on the same platform and use the same battery, which also saves money in disguise. Plug-in tools: cheap and powerful, and can work continuously for a long time, but they should be used near the socket.
Extended data
When using a hand drill, please pay attention to the following items:
1, hand electric drill with metal shell, its power cord generally adopts moisture-proof three-core rubber cord, in which the black or yellow-green core wire is the grounding wire, which should be connected to the electric drill shell; The plug adopts single-phase three-column plug, the largest copper column is the grounding column, and the pile head of the corresponding socket hole must be firmly connected with the grounding system (or the zero connection system).
2. For the hand drill that has been put on hold for a long time, the insulation resistance of the winding to the ground must be measured with a 500-volt megohmmeter before use (generally, it should be greater than 0.5 megohmmeter); If the insulation resistance is less than the allowable value, it should be dried.
3. When using a hand electric drill with a metal shell, you must wear insulating gloves, insulating boots or stand on an insulating platform (mat).
4, the power cord shall not pass through the driveway or sidewalk; Two electric drills are not allowed to share a pin or switch.
5, mobile electric drill, should hold the electric drill handle and rubber insulated wire at the same time, in order to prevent the electric drill and wire joint loose.
6, drilling, don't be too hard; When the rotation speed of the electric drill is very low, the pressure should be relaxed to avoid overloading and heating of the electric drill and damaging the insulation.
