Score: 78/100
DeWalt DWE402W 2-inch, black
Score: 65/100Rankings
The DEWALT DW840 is a powerful 7-inch angle grinder designed for heavy-duty grinding and cutting tasks. Its 13-amp motor delivers substantial performance, making it a favorite for professional use. However, its significant weight and lack of modern electronic safety features are notable trade-offs.
The DEWALT DWE402W is a compact, entry-level 4.5-inch angle grinder suitable for light-duty tasks. Its primary advantage is its manageable weight and brand reliability, though it lacks the advanced features of higher-end models. It is best suited for users who need a basic, reliable tool for occasional use.
