Thanks, I have a Ryobi hammer drill driver and seems to work perfectly with masonry. If need be I will take your advice however I have found the idea of using self-tapping screws to drill through the metal works very well. I used a #8 and #10 and pierced the metal in no time. Threw the screws away and used new ones on the next hole. No more dulling bits.
