Description
At 9/16″, this arbor spacer bridges the 1/2″ and 5/8″ positions in the Mini-Pro spacer range. On the 3/4″ bore spindle, using one 9/16″ piece instead of stacking a 1/2″ and a 1/16″ reduces mating surfaces in the spindle assembly, keeping tolerance stack-up lower. The machined steel body has precision-ground parallel faces that seat flat against adjacent cutters, collars, and spacers. Freeborn’s consistent bore tolerances across the full spacer lineup ensure this piece fits the 3/4″ spindle with the same close, repeatable fit as the narrower and wider sizes. A practical choice in any Mini-Pro accessory kit that aims to minimize parts count while reaching exact target stack heights.
