Our take on the DeWalt DWE4120 4-1/2" Paddle Switch Angle Grinder

The DeWalt DWE4120 is a corded 4-1/2 inch angle grinder with a 9 amp motor that spins at 12,000 rpm. Its slim body, low-profile jam-pot gear case and 3.9 lb weight make it easier to hold in tight spots and overhead work than bulkier grinders. The paddle switch, tool-free Quick-Change wheel release and one-touch guard speed up wheel changes on the job. It suits metalworkers, welders and contractors who want a light, tough grinder for cutting and grinding, though it lacks the variable speed and tool-free guard adjustment some rivals offer.
