I’m drilling a hole into my outer wall and there is a random metal bit inside the wall. There are no studs or wires... what is it? In the picture it is just the most bottom part of the hole ( it’s very hard to see srry )
If its a concrete block home it could be the rebar used to tie the roof to the foundation or a tie strap. Then again I have dropped an entire saw into a wall and had to leave it because I couldn't get it out. Someone could have also run a ground or bonding strap depending on the construction. It up to you on whether or not to cut it without looking at the entire construction.
