A rotary hammer is a power tool that can perform heavy-duty tasks such as drilling and chiseling hard materials.[1] it is similar to a hammer drill in that it also pounds the drill bit in and out while it is spinning. however; rotary hammers use a piston mechanism instead of a special clutch. this causes them to deliver a much more powerful hammer blow; making it possible to drill bigger holes much faster.
