Overview
The DEWALT DWE4120 is a corded electric grinder running on 120 volts with a 1000 watt motor and a no-load speed of 12,000 RPM.
Corded power at 1000 watts paired with a 12,000 RPM top speed points to a grinder built for cutting, grinding and surface prep rather than a low-speed polishing tool. Corded operation means no battery to manage, at the cost of needing an outlet or extension cord on site.

Who it's for
Tradespeople and DIYers who want steady corded power for grinding, cutting or deburring metal and masonry, and who are not tied to a cordless battery platform.
Pros and cons

Performance notes
The 1000 watt motor at 12,000 RPM gives consistent output as long as the tool stays plugged in, since corded grinders do not lose speed as a battery drains the way cordless models can.
