Hi, this is my first post. really need some help as the walls in my house are driving me crazy. When ever I need to drill them I have nothing but problems. They are made from what I can only describe as pebbles and concrete. Once I have drilled through the layer of plaster, the problems start. trying to drill any further is impossible, or at least it has been so far. Most times I hit one of the pebbles and the drill skips like crazy. If I can get a straight hole, I can never get it deep enough. I've lost count if the number of drill bits I have ruined. Anyone advice on this would be appreciated.
