Score: 78/100
Ryobi ONE+ SDS Plus Rotary Hammer
Score: 72/100Rankings
The DeWalt DW511 is a reliable corded hammer drill featuring a powerful 7.8 Amp motor and ergonomic design for heavy-duty masonry and construction tasks. Its main drawback is the corded design, which limits mobility and requires access to power outlets. It is best suited for professional contractors and DIYers working in areas with easy access to electricity.
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.
