The steps for replacing the drill bit with an electric drill are as follows:
Prepare relevant tools, such as drill bits that need to be replaced, drill keys, etc., and unplug the power plug or turn off the power switch to ensure that there is no danger when replacing the drill bit.
Hold the hand drill tightly with one hand, and hold the gourd mouth of the hand drill or press the button at the end of the drill with the other hand. Use force or clockwise rotation to expose the hole or chuck where the drill bit is installed.

Take out the drill bit to be installed, place it on the exposed hole at the front end of the electric drill, and rotate clockwise by hand to clamp the drill bit. When pushing in the drill bit, you should hear a slight “jamming” sound.
Adjust the depth position of the stuck drill bit into the hole, and use a special key or wrench to tighten and lock it clockwise.
Insert the power cord of the hand drill, power on the plug, idle for 2 seconds, and observe whether the drill bit of the hand drill is securely installed.
Attention: When replacing the drill bit, make sure that the new drill bit matches the specifications of the electric drill to avoid damaging the electric drill or the drill bit. At the same time, be careful during operation to avoid injury. If unsure how to replace the drill bit, it is recommended to seek professional assistance in replacing it.
