Some Tips:

We don't recommend hitting rebar, as you'll end up with a toothless bit.

The set screws (small bolts) holding the centering bits tend to back out with vibration, so applying some thread locker and letting it cure overnight prior to use.

In order to the locking screw more stable on the drill and for your sefety, please as the clockwise to use it when you drill the wall holes, thank you.
