Overview
The DongCheng DSM14-115 is a corded electric angle grinder built around an 800 watt motor spinning at 11,800 RPM. At 3.3 pounds it stays light for one handed grinding, cutting and surface work on metal or masonry.
DongCheng builds mostly for trade and industrial buyers rather than casual DIY shelves, and the DSM14-115 reflects that: a corded design with no battery to manage, a straightforward trigger, and a motor sized for repeated use rather than occasional touch-ups. Disc diameter is not listed in the available specs, so confirm it matches your accessories before ordering.
- 800 watt corded motor
- 11,800 RPM no-load speed
- 3.3 pound weight
- 120V AC power source
Who it's for
Fits users who want a dependable corded grinder for metal fabrication, weld cleanup or masonry cutting without battery downtime. Less suited to anyone who needs cordless portability on a job site with no nearby outlet.
Strengths and trade-offs
Drawn from this product's published specifications.
- Corded power means no battery to charge or replace
- Light at 3.3 pounds for extended handheld use
- High 11,800 RPM suited to grinding and cutting
- Disc diameter isn't listed in the specs
- Cord limits reach away from an outlet
- No accessories or case mentioned in the listing
Performance notes
The 800 watt motor drives the wheel to 11,800 RPM, a speed range built for material removal on metal and masonry rather than fine finishing work. Being corded, output stays constant regardless of battery charge, which matters for longer grinding or cutting sessions.
