Overview
The BLACK+DECKER BDEG400 is a 120V corded angle grinder weighing 2 kilograms with an 800-watt motor running at 10,000 RPM. At $45.99, it is the most affordable corded grinder in this batch by a significant margin, and its 7,300-review count is the largest of any product here, giving buyers an unusually large pool of real-world feedback.
The 10,000 RPM speed is below the 11,000 to 12,000 RPM range seen in mid-range and premium corded models, and the 800-watt motor is modest compared to the DEWALT DWE402 at 1,320 watts. For occasional home use, these limitations are unlikely to matter. For regular trade use, the gap in power and likely in durability becomes relevant.
The 2-kilogram body weight is among the lightest corded options in this batch, which helps with handling and fatigue. Buyers who cut and grind occasionally and want a recognizable brand at a low price will find the BDEG400 is difficult to beat on value. The 50 monthly purchases signal steady but moderate ongoing demand, consistent with a tool that occupies the budget entry segment.
Pros
- Lowest price in the corded grinder lineup at $45.99
- 7,300 reviews at 4.5 stars, the largest review pool in this entire batch
- Lightweight 2-kilogram body for comfortable handling and reduced fatigue
- 800-watt motor suitable for everyday home cutting and grinding tasks
Cons
- 10,000 RPM is the lowest speed among corded models in this batch
- 800-watt output limits capability for heavier professional grinding work
- Positioned as a home-use budget tool rather than a trades-grade daily driver

Performance notes
Corded electric on 120V, 800-watt motor, 10,000 RPM no-load speed, 2 kilograms. The combination of the lightest weight class and modest motor output makes this a tool optimized for ease of use over raw power. Best suited for light metalwork, tile cutting, paint or rust removal, and home repair tasks rather than sustained fabrication or construction grinding.
What buyers say
The massive review base reflects the BDEG400's widespread adoption as a household grinder. Owners consistently rate it as a capable, affordable tool for what it is designed to do. The most common feedback theme is that it meets expectations for occasional home use but is not a replacement for heavier professional grinders. Durability under heavy workloads is a secondary concern noted in some reviews.
