Cordless models have not taken over the rotary hammer market, but drilling performance of some cordless SDS-plus hammer brands is nearly the same as its corded brother. With the rapidly improving battery amp hours, battery run time is now increasing in leaps and bounds, even in heavy-duty applications, with little or no increase in battery size or weight. What’s left is price. Battery technology continues to be expensive.

However, for personnel who work mainly on lifts, swing stages or in the remote corner of large job sites, the continued improvement in battery tools makes the cost for this tool mobility insignificant or in some cases, completely irrelevant. The cost to set up corded power includes additional equipment, including generators, fuel to power the generators and power cords.
