Hey Reddit! I’ve been doing some minor retouches on my home and one of them has been replacing air registers. On 2 out of 3 I’ve drilled pilot holes on either side and hit something metal (as noticed on the end of the drill bit) about an inch into the wall. Is this part of the vent? I’m nervous about trying to drill through anything that doesn’t want to be drilled. Thanks in advance for the advice! via /r/DIY https://ift.tt/2QZU2OM
