Metabo's SE 12-115 burnisher basically is a slow, variable-speed angle grinder with an extended spindle that fits accessory wheels up to 4-inches wide and 4 1/2-inches in diameter. A key on the spindle fits a groove in the wheels to provide a positive mechanical drive, and spacers of different widths are supplied for fitting wheels shorter than the spindle length. The tool body is held perpendicular to the direction of an angle grinder, and a large guard and handle assembly clamps to the head of the tool.
