The DWE4011 is a 4-1/2 inch grinder with a 7 amp AC/DC motor that spins at 12,000 RPM, the highest no-load speed among the standard 4-1/2 inch models here. The higher speed is designed for faster material removal and better overload handling.
Its One-Touch guard lets you reposition the guard without a tool, which is a real safety advantage, because a guard turned to the wrong angle is the main reason people remove it. A hex wrench replaces the spanner wrench, which means the tool is easier to service with common toolbox items. Compared with the Bosch GWS8-45 at 7.5 amps and 11,000 RPM, the DeWalt has less current but a higher speed, so the choice is about feel and guard design rather than raw capability.
The tool is a standard slide-switch or paddle design, so check which version you are buying and always use the side handle. Check the wheel's rated speed against 12,000 RPM, since a wheel rated lower is dangerous. Brush wear is the main maintenance item. If you switch between cutting and grinding often, buy a spare guard so you can leave one configured for each job.
