While you can use a standard drill, I have done so many times but it is slow and the bit tends to wander particularly if you happen to hit a stone in the cement. It may also be that the prolonged time produces additional abrasion I don't know but the hole tends to be that bit more sloppy. This is less common in block or brick however it requires a quite precise hole for the screws to hold well. For this reason alone a hammer drill is the preferred instrument. They go into concrete much quicker and therefore form a much more precise hole.
