Score: 70/100Rankings

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.

This DEWALT model is a versatile corded angle grinder capable of using both 4.5-inch and 5-inch wheels. It offers a comfortable trigger switch and moderate weight. It is best suited for users who need flexibility in wheel size for various grinding and cutting applications.
