Description:

The Dongcheng DSM03-180 2200W Angle Grinder is a powerful, heavy-duty corded electric tool designed for professional metal grinding, abrasive cutting, weld preparation and industrial maintenance applications.

Equipped with a 2200W high-power motor, the DSM03-180 delivers a listed 8,300 RPM no-load speed, providing strong performance for demanding grinding operations in engineering workshops, fabrication facilities and construction environments.

The grinder supports a maximum 180mm (7-inch) wheel diameter with a 22mm wheel bore, allowing the installation of suitably rated and compatible abrasive accessories.

One of the model’s key features is Soft Start technology, which gradually increases motor speed during startup. This helps reduce the sudden starting jerk associated with high-powered angle grinders, providing smoother initial operation.

The 7-inch wheel capacity provides a larger working diameter than standard 4-inch and 5-inch angle grinders, making it suitable for applications requiring greater wheel reach and material removal capacity.

The DSM03-180 is also listed with a spindle lock mechanism, designed to assist with grinding wheel replacement when the tool is switched off and disconnected from the power supply.

A large trigger switch provides convenient operating control, while the approximately 5.0kg net weight reflects its heavy-duty tool configuration.

The Dongcheng DSM03-180 2200W 180mm Angle Grinder is suitable for metal fabrication workshops, steel construction projects, engineering maintenance, industrial repair and other applications requiring a high-powered 7-inch grinding machine.

Specification Note:

The DSM03-180 specifications are corroborated by multiple distributors and retailers. Dongcheng’s manufacturer catalogue also documents a separate DSM180A model with matching 2200W, 8,300 RPM, 180mm, 22mm and 5.0kg specifications, but those two model codes should not be treated as interchangeable without confirmation.

The exact DSM03-180 spindle thread, rated voltage, operating frequency and accessory package have not been independently confirmed from an official model-specific datasheet.
