Yesterday I was drilling a couple of 5mm diameter drill holes for a curtain rail
I had an hammer drill (electric)
I first tried with the hammer action off, and it made a perfect 5mm hole, but not quite long enough for the raul plug
I noticed that underneath the paster is a very hard substance, something like steel
I cant get through it, with or without hammer action on, with concrete or HSS drill bit, makes no difference
When I turned on Hammer action, it made the 5mm hole turn into a 7 or 8 mm diameter hole, because it makes the drill go all aggressive, if you know what i mean
After 2 failed holes, I gave up frustrated.
What can i do ?
