Power Tool Buying Guide for Rotary Hammer
Rotary hammers are amazing power tools. Rotary hammers usually also have a function for chiseling. Do not get confused between a rotary hammer and a hammer drill, because they are two separate power tools. Both are used for concrete work and both hammers in and out while spinning. However, the internal mechanism is much different and much more robust with a drill hammer. A rotary hammer uses a piston mechanism rather than a clutch.
