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 Bosch 1191VSRK is a lightweight, corded hammer drill offering an exceptional power-to-weight ratio with a 7 A motor and 48,000 BPM impact rate. Its single-speed operation and keyed chuck are trade-offs for its rugged durability and compact size. It is ideal for professional contractors needing a reliable tool for high-volume concrete drilling.
