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 DongCheng DSM17-115P is a corded electric angle grinder running on 120 volts AC. Its 1100-watt motor spins at 11800 RPM, which is competitive with corded grinders priced well above it. At 4.2 pounds the DSM17-115P stays manageable during overhead work and extended grinding sessions without unusual fatigue.
Based on specs and verified owner reviews, 472 buyers have rated it 4.7 stars, an unusually high score for a sub-$35 corded tool. Owners report the power output feels proportionate to tasks like weld grinding, rebar cutting, and surface prep. The corded design means runtime is unlimited as long as a 120V outlet is available, which suits workshop and garage use well.
The principal caveat is DongCheng's limited service and parts network in North America. Owners who are comfortable with basic maintenance and do not depend on local service centers will get the best experience from this grinder. Published specs do not include disc size confirmation or guard details, so verify those before purchasing accessories.
Pros
- 1100-watt motor at 11800 RPM matches or beats corded grinders costing significantly more
- 4.7-star rating from 472 owners is strong evidence of consistent real-world satisfaction
- 4.2-pound weight reduces fatigue during extended or overhead grinding
- Corded design provides unlimited runtime from any standard 120V outlet
- At $33.91 it is one of the most affordable entry points for a 1100W corded grinder
Cons
- DongCheng has minimal service center and parts availability in North America
- Key specs such as disc diameter and guard adjustability are not confirmed in the listing
- Limited brand recognition may reduce resale value and warranty confidence

Performance notes
Drawing from a 120V AC source at 1100 watts, the DSM17-115P sustains 11800 RPM under load, placing it firmly in the same speed range as mainstream corded grinders. The 4.2-pound body suggests a standard-duty chassis suited to grinding welds, cutting sheet metal or rebar, and surface prep rather than continuous heavy stock removal. No battery dependency is a practical advantage for stationary workshop tasks.
What buyers say
Owners consistently describe the DSM17-115P as more powerful than its price implies. Common praise centers on smooth disc spin-up and adequate torque for everyday grinding and cutting jobs. A smaller segment raises concerns about long-term durability and limited brand support, but short-term owner satisfaction is high given the 4.7-star average.
