　　What should I do if the small electric drill bit cannot be pulled out?

If the small electric drill bit cannot be pulled out, it may be due to rust or damage to the locking mechanism. Here are some workarounds:

Lubricant: Try spraying some lubricant between the drill bit and chuck to work it into areas that may be rusty. Wait a few minutes and then try to pull out the drill bit.

Tap: Lightly tapping the side of the drill bit with a rubber mallet can sometimes help, as tapping can help the lubricant penetrate better and can also release some of the locks.

Heating: Use a hair dryer or a match to heat the chuck of the electric drill bit, and then try to pull it out. Heat expands the metal and helps loosen the rusted parts.

Pull out harder: If all else fails, you may need to use a little more force. Using a suitable tool, such as pliers or a wrench, carefully try to pull the drill bit out. But be careful not to use too much force to avoid damaging the drill bit or chuck.

Professional Repair: If you still can’t get the drill bit out, it’s best to seek the advice of a professional repairman. They may have more professional tools and methods to solve the problem while also avoiding unnecessary damage.

Remember, make sure the drill is powered off and the batteries are removed before trying any method. Safety first!
