Description:
The Dongcheng DSJ02-10 105W Die Grinder is a compact, high-speed corded power tool designed for precision grinding, polishing, deburring and detailed surface finishing applications.
Equipped with a 105W electric motor, the DSJ02-10 delivers a 30,000 RPM no-load speed, making it suitable for fine grinding operations on small metal components, moulds, jigs and intricate workpieces.
The grinder features a 3mm (1/8-inch) maximum collet size, allowing the use of compatible small-shank grinding points and finishing accessories.
With a maximum 10mm grinding wheel diameter, the DSJ02-10 is designed for controlled detail work rather than heavy-duty material removal.
One of its key advantages is the small and compact body with a short half-structure design, which helps users handle the tool conveniently when working on narrow or difficult-to-access areas.
Weighing just 0.8kg, the grinder offers lightweight handling for precision workshop operations.
The manufacturer-listed accessory package includes a wrench and carbon brush, with colour box packaging.
The Dongcheng DSJ02-10 105W Mini Die Grinder is suitable for mould-making workshops, metal fabrication, tool maintenance, small-part finishing and engineering applications requiring a compact, high-speed grinding tool.
