Hi,
I need to hang a mirror but it is a very old house so the walls are made of solid granite stones (covered by ~1cm of plaster + wall paper). My drill is a 600W Black and Dekker and I generally use it for drilling wood but I did once try drilling into concrete to screw down a saddle board but I got nowhere. I pressed down on the drill but it didn't advance into the concrete at all, the drill bit just heated up more and I was worried that if I applied more presure the bit might simply break. So I expect the granite wall will be comparable to trying to drill concrete. From some brief googling it seems my first mistake when trying to drill concrete was that I did not enable the hammer mode on the drill I was just using drill mode. So, assuming I do use the hammer mode this time, is it likely to work ? Will 600W + hammer mode drill holes in a granite wall ? If so how long should it take to make a hole of ~1.5 inches deep using a drill bit with ~0.75cm diameter ? Any other advice for drilling into granite walls ?
Thanks,
Usjes.
