For bench motors with shafts smaller than 1 inch, a 3M™ Telescoping Wheel Flange Adapter (Part No. 5) can be inserted into the center hole to fit 1/2 inch, 5/8 inch, 3/4 inch or 7/8 inch shafts. When a greater thickness of bristle discs is needed, 3M™ Spindle Extender Adapters (Part No. 30134) can be added to increase the disc capacity of the flange adapter. These additional adapters are sold separately.
