The fundamental design of a hammer drill or hammer driver is the same as that of drills. The only difference is the way in which the hammer mechanism vibrates the bit to cut concrete.
A rotary hammer or the combination hammer (combihammer) is the hammer drill's big sister.
Core drills are among the most rare kinds of drill. It's essentially a big motor, sometimes attached to a frame that holds it steady as it drills.
Ground augers, often referred as earth augers, use either AC or natural gas to make their motors powerful.
