The DeWalt DWE4120N is a corded 4-1/2 inch angle grinder with a 9.0 amp motor spinning at 12,000 RPM. That combination puts it among the more powerful small grinders, so it holds speed through heavy cuts better than lower-amp 4-1/2 inch models. It suits metalworkers, welders and fabricators who cut and grind steel all day and want a light one-hand tool. Against premium grinders it gives up some refinement and dust protection, but it delivers the power and speed most shop work needs.
