Always always, always check for any electricity cables running through the wall before you start drilling. Catching a live cable when drilling
2.Never wear loose clothing or dangling jewelry which could catch in the drill as you lean over it.
3. The drill bit will become hot with use so keep you hands off it.
4. Make sure you use the correct drill bit for the type of wall you are drilling into.
5. If you are drilling into tiles use a specialist tile drill bit and stick a little piece of masking tape over the area to stop the drill from wandering.
6. If you are drilling into plasterboard, tap the wall to find where it is not hollow as this will be where the wooden joist is - aim to drill only into this. Or to be completely accurate just use a joist detector.
7. Finally, always use a proper purpose made extension cord if you need a longer wire for your drill and never pick the drill up by its cord.
