Hi,
I'm trying to put up some supports for small shelves, I've got a set of screws/wallplugs (brown). I forget what size they are, but I know I need a
7mm drill bit to accommodate the wallplugs. Do I need to pilot drill the hole first, and if so, what size(s) would you recommend starting with/stepping up through? The walls are about 1 inch plaster, then brick, which means that my hammer drill chews a huge hole in the plaster, and then struggles with the brick. I'm going out tomorrow for some new masonry drill bits, any suggestions as to make/type? (My drill is a chuck-key type).Can anyone advise, or point me towards a decent guide to doing this without ending up with a hole I can stick my head through?? Thanks a lot!
