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 AVID AG640 runs on 120V AC power and delivers a 1000-watt motor at 11500 RPM, covering the typical demands of cutting, grinding metal, and surface prep at $45.99. The combination of meaningful wattage and a low price makes it a frequent choice for home workshops and occasional job-site use.
At 4.19 pounds, the AG640 is lightweight for a corded grinder with this power output, which helps reduce hand fatigue during extended use. The 341-review count and 200 monthly purchases place it among the higher-demand items in this batch, validating its position as a budget workhorse.
The 4.3-star rating is honest, sitting below the premium Milwaukee models in this batch, reflecting the trade-off between price and build quality. For buyers who will not push the grinder hard every day, it delivers well above what its price suggests.

Performance notes
The AG640 delivers 1000 watts from a 120V corded connection at 11500 RPM. The 4.19-pound weight is notably light for a 1000-watt grinder. Corded operation provides unlimited runtime, giving it a clear advantage over battery-powered tools for sustained tasks such as metal grinding and weld cleanup.
What buyers say
Owners broadly praise the AG640 for delivering strong performance at a low price. Critical reviews tend to focus on plastic component quality, suggesting the tool is best suited to moderate-frequency use rather than all-day professional workloads. The high monthly purchase rate confirms strong buyer satisfaction relative to price expectations.
