Score: 88/100Rankings
The DEWALT DCD799B is a bare-tool, 20V MAX* ATOMIC COMPACT SERIES brushless hammer drill designed for high performance in confined spaces. Its primary limitation is the lack of included batteries and charger, requiring users to invest in the 20V MAX ecosystem. It is best suited for professionals such as electricians and plumbers who need maximum power in tight areas.
The Ryobi R18SDS-0 is a compact, cordless 18V SDS-Plus rotary hammer drill designed for light to medium-duty tasks such as drilling into masonry and light chiseling. Its key strength is its lightweight design and versatility with four operating modes, making it a practical bridge between standard drills and full-sized rotary hammers. However, its lower impact energy limits its effectiveness for heavy professional demolition or large-diameter work.
