I am fixing a wall mout for a flat screen TV. I was going to use wrall bolts through a drylined wall into solid brick work. I got my holes drilled to 12mm with a hammer drill (DRILLED SMALL THEN STEPPED UP). The problem is my holes in the brickwork seem to have gone slightly oversize where the wrall bolts are spinning. Any one have a quick fix or a way of fixing this (I DO FEEL REALLY SILLY BY THE WAY
). Or can some one tell me why my holes have gone oversize??? I dont want to try and drill to another size incase I oversize the new holes.
Thanks in advance
