For my air con install, I need to drill a 60mm hole in masonry using my 1500w Titan TTB278SDS drill. They are drywall skinned concrete blocks. Very tough, very heavy. The drill says that it can do up to 32mm in masonry. I have a good diamond core bit.Do you think I need to get hold of a more powerful drill or do you think I will be ok? via /r/DIY https://ift.tt/2sQOtro
