Hi,
I'm trying to drill my concrete floor to enable me to screw down some plywood.
I am trying to drill to a depth of 60mm, with a 8mm masonary drill bit. I've been using the hammer action, medium to fast setting and had no real problems with the 5mm pilot. However, I've now burnt out a couple of drill pits. The floor is pretty tough in places, perhaps I am pressing too hard or trying to drill a too big a hole, but any advice from somebody who has experience in this area would be very much appreciated.
Many thanks - I'm getting desperate...
