I recently bought a Dewalt 4.5" grinder and bought a masonry cut off disc. I tried to use it to cut some slits in a cement slab so it can make some easy break points once I get out the jackhammer. It was barely making a dent in it, and the blade would just start getting loose in the tool and turning freely. Is there a proper way of doing this? I was expecting to go in like an inch or so, and I did not do any more damage to the slab than if I took a rock and scraped it against it. Could I have been doing something wrong? Or is this just a very long process?
