Rotary hammer "difference"
A hammer-drill uses 2 grooved plates that rotate opposite of each other. When they slip and the grooves connect, a bang is heard. This bang "hammers" the chuck, which in turn, drives the bit into the masonry material.
A rotary hammer is extremely more efficient than a hammer drill, because it drives a piston that pounds the chuck with measurable impact energy.
There's really no question which is better. Hammer drills are loud and cheaper. rotary hammers are bigger, quieter, more expensive, and do the job in 95% less time, with less effort.
