*PLEASE NOTE: Your buffer or grinder must have a 5/8” – 11 arbor shaft to properly mount buffing wheels and flanges. The arbor shaft of the polisher must be at least 3/4″ in length, as it’s possible that the buffing wheel will contact the buffer itself, or you may not have enough thread to properly tighten the nut. If the shaft is less than 1” or you have doubts about length, we recommend purchasing the 2″ extender kit which has sufficient thread and moves the buffing wheel away from the polisher.
