The electric hand drill is a commonly used drilling electric tool powered by an AC power source or a DC battery. 

If you don’t use the electric hand drill correctly, you may hurt others alive.

 So what should you pay attention to when using the electric hand drill correctly?

First: Ensure the safety of the circuit: Before and during use, ensure that the circuit is normal, the power supply connected to the power supply is free of faults, and the leakage of the skin is broken. It can be used only if it is wrapped with bare insulating tape.


If you are using a cordless drill, you can avoid this.

Second: to ensure the safety of the switch device: turn off the switch when the hand drill is not in use to prevent the next use of the power hand drill from turning suddenly and hurting people.

Third: Check before use: Before using the electric drill, turn it on for 0.5 to 1 second after turning on the switch. Check whether the transmission part is flexible, whether there is abnormal noise, whether the screws are loose, and whether the commutator sparks are normal.

Fourth: the control method should be correct: hold both hands tightly when drilling holes with the electric drill, try not to operate with one hand.

Fifth: Choose the correct drill bit: The drill bit of the electric hand drill cannot be used with a notched drill bit, and the downward force should not be too large when drilling to prevent the drill bit from being interrupted.

Sixth: The drilling force should be moderate: When the electric hand drill is drilling the object, the drilling force should not be too strong, and no strong force can be used to prevent the drill or wire from flying out and hurting people.

Seventh: Troubleshooting in time: If you find large sparks on the commutator and overheating of the electric drill during use of the electric drill, you must stop using it and perform inspections, such as removing dirt, replacing worn-out brushes, adjusting the spring pressure of the brush holder, etc. use.
