Powerful motor and high removal capacity: Typical DCA 9′′ grinders have motors rated around 2020 W. That kind of power gives the grinder enough torque and speed to cut, grind, or shape heavy materials — steel, concrete, stone, thick metal sheets or structural metal.
Large disc size for big jobs: With a 230 mm disc diameter (and central hole size ~22 mm) — common specs on DCA 9′′ grinders — the tool can take on big surfaces, long metal beams, thick pipes or large masonry/concrete surfaces.
