Score: 78/100
DeWalt DWE4012 2-inch
Score: 78/100Rankings
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 DWE4012 is a reliable 4.5-inch angle grinder featuring a powerful 850W motor and high 12,000 RPM speed. It stands out with user-friendly features like overload protection and quick-change wheels, though the paddle switch may cause fatigue during long sessions. It is best suited for general-purpose cutting and grinding tasks where speed and convenience are prioritized.
