Overview
The DongCheng DSM17-115P is a corded electric angle grinder rated at 120 volts AC with a 1100 watt motor. It spins at 11800 RPM and weighs 4.2 pounds.
The 115 in the model number lines up with a 4.5 inch disc size, the standard for compact angle grinders used on metal cutting, grinding and light fabrication work. At 4.2 pounds it sits in the lighter end of corded grinders, which matters for one handed control on overhead or vertical cuts.

Who it's for

Performance notes
The 1100 watt motor and 11800 RPM disc speed give this grinder enough power for metal cutting, deburring and weld cleanup with a 4.5 inch disc. Corded power means no runtime limit or battery swap, at the cost of needing an outlet or extension cord nearby.
