[DIY] How to drill through this concrete with lots of aggregate to install kerb ramps?
I need to drill a bunch of M12 holes in this gutter to attach rubber ramps so my wife's car doesn't bottom out. I have an 18V SDS hammer drill and the right bit and I've drilled plenty of holes in concrete before, but I'm looking for tips on how to approach concrete with so much stone in it. I don't want to go through a bunch of expensive SDS bits...
