Is there a difference between these two types and if so what is the difference? Thanks
They are both used for concrete. A hammer drill has a clutch that makes the drill jab up and down, while a rotary hammer has a piston and has a more powerful punch into the concrete than a hammer drill. Its like a yugo and a Porche. They will both get you to point be, but the porche while do it quicker.
