Description
The 1/2″ wide arbor spacer is one of the most frequently used sizes in a production shaper kit. On the 3/4″ Mini-Pro spindle, this Freeborn steel spacer provides a single-piece solution for the half-inch cutter separations that appear regularly in stile-and-rail, cope-and-pattern, and panel-raising setups — replacing what would otherwise be a combination of narrower pieces. One spacer means fewer mating surfaces, simpler stack assembly, and less cumulative tolerance. Precision-ground parallel faces keep adjacent cutters and collars aligned, and Freeborn’s consistent bore tolerances ensure this spacer seats on the 3/4″ spindle identically to the rest of the Mini-Pro spacer set. When building a core selection of arbor spacers, the 1/2″ is always on the list.
