Tool Test: Rotary Hammers
A seasoned remodeler looks for the perfect concrete drill
A rotary hammer is the right tool for drilling concrete and masonry. It’s also great for chipping tile and breaking up concrete. Knowing which model to buy is difficult because you can’t test them in the store. Longtime remodeler Mark Clement makes choosing the right rotary hammer easy. He and three other professional remodelers tested seven 1-in. rotary hammers head-to-head. They compared the performance and features of tools from Bosch, DeWalt, Hitachi, Hilti, Makita, Metabo, and Milwaukee. A comprehensive sidebar discusses the differences between SDS-plus, SDS-max, and spline-style rotary hammers.
