The arbor features a 7/8-inch arbor hole and a 1.25-inch bolt hole diameter, enabling a secure mechanical interface between the brush and the drive spindle. It supports both attached spindle and flow-through spindle configurations, giving technicians flexibility across different grinder and drill setups. This arbor is intended for use with 3-inch, 4-inch, and 5-inch Weiler disc brushes, including Nylox disc brush models.
