Rotary Drill vs. Hammer Drill: What's the Difference?
Hammer Drill vs. Rotary Hammer. Hammer drills and rotary hammers (also called rotary hammer drills) both produce a pounding force that makes them extremely efficient at blasting through masonry. As the hammer drill spins, the bit chisels away at the masonry. The mechanical process that delivers this pounding action is what separates the two ...
