Steel Arbor Spacer, 1-1/4″ Bore, 1/2″ Wide

The 1/2″ wide arbor spacer is one of the most frequently used sizes on the Pro-Line spindle. On the 1-1/4″ bore, this Freeborn steel spacer provides a single-piece solution for half-inch cutter separations that appear regularly in heavy-duty stile-and-rail, cope-and-pattern, and raised panel setups — replacing what would otherwise be a combination of narrower pieces. One spacer means fewer mating surfaces, simpler assembly, and less cumulative tolerance in a stack that Pro-Line tooling already puts under higher loads. Precision-ground parallel faces keep adjacent cutters and collars aligned. Freeborn’s consistent bore tolerances ensure this spacer seats on the 1-1/4″ spindle identically to every other size in the Pro-Line set. Stock multiples.
