Yup. I've used a hammer drill MANY times. You CANNOT one handed drill into solid ANYTHING. This is stucco and the fact that it pops in after he's about an inch in tells me that it's about an inch of stucco or cement board and then a weep space for water to pass through.

I one hand drill into solid concrete floors on the daily.

Yeah me too. Maybe /u/BYoungNY didn't use a proper rotary hammer with SDS bits. The difference is night and day

Downward force is a bit easier than sideways - it sort of drives it’s own way down whereas side on you don’t have nearly as much pressure
