I live in a mid-50s ex council house and it seems that every time I try to do what should be a simple job I run into a problem.
Today I started to hang Venetian blinds in a window recess. However I can only drill through a centimetre or so of plaster before I hit something too hard for my drill. I'm using a masonry bit but it's having zero effect. How can I determine whether it's masonry and I should switch to the impact drill, or whether it's steel and I should either give up or buy a different kind of drill bit?
