Score: 70/100Rankings
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 Berserker 1-1/8" SDS-Plus Rotary Hammer is a corded electric tool designed for drilling and demolition in concrete and masonry. It features a robust 9 Amp motor delivering 4.5 Joules of impact energy and includes multiple operating modes with a safety clutch. While the 9.5 lb weight may cause fatigue, it is a dedicated tool for users requiring consistent high-impact performance in masonry work.
