Tips
- Ice Cube Method
If the magnetic hollow drill bit cannot be removed, try using ice cubes. First, wrap the ice cubes in a towel and apply it to the area near the magnetic hollow drill bit for a few minutes. Then attempt to remove it again—this should make it easier to detach. - Pliers Method
If the above method doesn’t work, try using pliers. Place the pliers on the teeth of the hollow drill bit and gently twist to remove it. Be careful to handle the pliers gently to avoid damaging the drill bit’s surface. Exercise caution during disassembly, as improper handling may damage the drill bit or the drill. - Lubricant Method
If the previous methods fail, apply lubricant. Evenly coat the interface between the hollow drill bit and the socket with lubricant, wait a few minutes, and then try removing the magnetic hollow drill bit again—it should come off easily.
In summary, there are multiple ways to remove a magnetic hollow drill bit. Try different methods to find a solution. If all else fails, seek professional assistance to avoid damaging the drill bit or socket.
