Ryobi ONE+ SDS Plus Rotary Hammer
Score: 72/100
DEWALT DCD805B
Score: 88/100Rankings

The DeWalt DCD805B is a compact, high-performance cordless hammer drill featuring a brushless motor and 2,100 in-lbs of torque. Its primary trade-off is the lack of included batteries and only two speed settings, which may limit control for some users. It is best suited for professionals and DIYers needing a versatile tool for tight spaces and masonry work.

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.
