DeWALT DWE4557 - 7" 120V 15A Corded Angle Grinder

[This review was collected as part of a promotion.] As as fluid-applied flooring installer we spend most of our days shot blasting and grinding concrete, and these 7" grinders are the only ones powerful enough to handle the job consistently. While they do wear out over time like any tool, they last about five times longer than any other brand we've tested—and we've tried them all. Plus, the brushes are inexpensive and easy to replace which is the main issue we run into.
