Rotary hammers can be used for “doweling” (repetitive drilling of large rebar anchor holes), and drilling through-holes in concrete and masonry walls. The hammering action helps break up the masonry so that it can be removed by the drill bit’s flutes.
A rotary hammer, also called rotary hammer drill is a power tool that can perform heavy-duty tasks such as drilling and chiseling hard materials. It is similar to a hammer drill in that it also pounds the drill bit in and out while it is spinning.
