The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less.

Context, not marks against it, and our read of the data, not a lab test.
Overview
The Metabo G12SR4 runs at 12000 RPM on 120V corded electric power, making it the fastest corded grinder in this batch. At 4 pounds and measuring 10.15 inches long by 4.5 by 2 inches, it is also among the most compact and lightest corded options available. The $49.00 price point, 4,900 reviews, and 4.6-star average make a compelling value case that is difficult to overlook.
Three hundred units bought last month confirms ongoing strong demand. No motor wattage is published in the listing, so buyers cannot directly compare output figures to the DEWALT DWE43116 at 1700 watts or the Bosch GWS8-45 at 900 watts. The compact 10.15 by 4.5 by 2-inch dimensions suit jobs with space constraints and reduce arm fatigue during extended overhead or sustained work. At 4,900 reviews, the G12SR4 is the second most-reviewed product in this batch behind the DEWALT DCG413B.
For buyers who prioritize speed, compact size, and proven budget value, the Metabo G12SR4 is a standout pick. The 12000 RPM speed exceeds most competitors in this category, including the Bosch GWS8-45 at 11000 RPM and the DEWALT DWE43116 at 9000 RPM, making it well suited for cutting, surface prep, and fast grinding cycles.

- 4,900 reviews at 4.6 stars demonstrates broad validated demand

- 300 units bought last month confirms active ongoing buyer adoption
Cons
